EXECUTIVE SUMMARY

Vascular plant surveys were initiated during fiscal year 1992 by the environmentally sensitive areas program to determine the baseline condition of threatened and endangered (T&E) vascular plant species on the Oak Ridge Reservation (ORR). T&E species receive protection under federal and state regulations. In addition, the National Environmental Policy Act (NEPA) requires that federally-funded projects avoid or mitigate impacts to listed species.

T&E plant species found on or near the U. S. Department of Energy's (DOE) Oak Ridge Reservation (ORR) are identified. Twenty-eight species identified on the ORR are listed by the Tennessee Department of Environment and Conservation as either endangered, threatened, or of special concern. Four of these have been under review by the U.S. Fish and Wildlife Service for possible listing (listed in the formerly-used C2 candidate category). Additional species listed by the state occur near and may be present on the ORR. A range of habitats support the rare taxa on the ORR: river bluffs, sinkholes, calcareous barrens, wetlands, utility corridors, and forests. The list of T&E plant species and their locations on the ORR should be considered provisional because the entire ORR has not been surveyed, and state and federal status of all species continues to be updated.

The purpose of this document is to present information on the listed T&E plant species currently known to occur on the ORR as well as listed species potentially occurring on the ORR based on geographic range and habitat availability. For the purpose of this report, "T&E species" include all federal- and state-listed species, including candidates for listing, and species of special concern. For project planning purposes, this report is most useful in alerting planners and site managers that T&E species are known to exist in certain areas. Consideration of T&E plant habitats is an important component of resource management and land-use planning; protection of rare species in their natural habitat is the best method of ensuring their long-term survival.

1. INTRODUCTION

The U.S. Department of Energy's (DOE's) Oak Ridge Reservation (ORR) encompasses approximately 15,000 ha in the Ridge and Valley physiographic province of Tennessee. Threatened and endangered (T&E) plant species on the ORR may receive protection under federal and state laws.

The federal Endangered Species Act of 1973 (ESA), as amended, provides for the listing and protection of species in danger of becoming extinct and conservation of the habitats on which such species depend. ESA makes it illegal to kill, collect, remove, harass, import, or export an endangered or threatened species without a permit from the Secretary of the Interior. Federal regulations that implement Sect. 7, "Interagency Cooperation," of the ESA (16 U.S.C. 1531 et seq.) require federal agencies to assess the impacts of their actions on plant and animal species listed by theU. S. Fish and Wildlife Service (FWS) as threatened or endangered and on areas designated or proposed for designation as critical habitat. FWS recommends that federal agencies also consider species that are candidates for listing during environmental planning since candidate species may eventually be listed.

The National Environmental Policy Act (NEPA) requires that federally-funded projects avoid or mitigate impacts to listed species. DOE NEPA implementing regulations (10 CFR 1021) require consideration of adverse affects to "environmentally sensitive resources" including "federally listed threatened or endangered species or their habitat (including critical habitat), federally proposed or candidate species or their habitat, or state-listed endangered or threatened species or their habitat."

Plant species listed by the Tennessee Department of Environment and Conservation (TDEC) are also provided limited protection by the Tennessee Rare Plant Protection and Conservation Act of 1985 (Tennessee Code Annotated Title 11-26, Sects. 201-214). This act protects listed plant species from removal or destruction without the consent of the landowner. DOE supports the protection of state-listed species on the ORR.

The DOE Environmental Restoration and Waste Management Program (EM) has supported a program to survey the ORR for species listed as T&E. Vascular plant surveys were initiated during fiscal year 1992 by the Environmentally Sensitive Areas Program to determine the baseline condition of T&E vascular plant species on the ORR. The primary concern of the T&E plant survey project is the identification of vascular plant species occurring on the ORR that are federally listed as endangered or threatened, candidate species for federal listing, listed by the State of Tennessee, or are of special concern (considered at risk) based on other sources. Additionally, the surveys allow the identification of potential habitat for such species on the ORR and the identification of potential threats to such species on the ORR.

Data collected during these surveys aids in Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) remedial investigations on the ORR. The surveys also provide data for EM decision documents, ensure that remedial decisions have legal defensibility, provide a baseline for ensuring compliance with principal legal requirements [including ESA, NEPA, CERCLA, National Resource Damage Assessments (NRDA), and the Clean Water Act (CWA)] and will increase public confidence in DOE's adherence to all related environmental resources rules, laws, regulations, and instructions.

1 2 2. METHODS

The ORR T&E plant survey project can be broken down into three primary tasks: compilation of existing data, field surveys, and documentation.

2.1. COMPILATION OF PRE-EXISTING DATA

Data existing prior to the initiation of this project was compiled and published during Fall 1993 (Cunningham et al. 1993; Pounds, Parr, and Ryan 1993). Updated state and federal rare plant lists were obtained from TDEC and the Federal Register. Data from previous plant surveys on the ORR were reviewed and evaluated for completeness. A preliminary map of areas for which rare plant data was available and was prepared using geographic information systems (GIS); this coverage was then overlaid onto the EM waste areas map to determine the availability of rare plant data for the waste areas. The following data sets were compiled:

• Vascular plants documented to occur on the ORR

• T&E vascular plant species not documented fromth e ORR but known to exist in areas near the ORR

• T&E vascular plant species occurring in the Ridge and Valley Physiographic Province of Tennessee which potentially occur in habitat types found on the ORR

• Characterization data for T&E vascular plant species occurring on the ORR, near the ORR, or potentially within habitats present on the ORR (i.e., range information; habitat requirements; life cycle characteristics such as dates of emergence, flowering, and setting of fruit or seed; and distinguishing morphologic features)

• Descriptions of environmentally sensitive areas on the ORR known to contain rare plants or rare communities

• Landscape elements frequentlyassociate d with rare species on the ORR (landscape elements are land types and formations which provide the underlying structure for the development of biological habitats and communities; many T&E species are associated with or restricted to certain land types/formations)

2.2. FIELD SURVEYS

Field surveys were conducted to locate and identify T&E plant species and sensitive habitats on the ground. Areas of the ORR lacking sufficient information concerning rare plants and sensitive habitats were ranked for urgency of fieldsurvey s and selected for site visits in a roughly descending order based on the following priorities: (1) EM waste areas, (2) areas where projects have been proposed, (3) areas most likely to be impacted in the near future, (4) areas containing landscape elements and natural communities associated with T&E species, (5) remaining areas of the ORR. In addition, selected areas with known rare plant populations were visited to collect baseline data on those populations. 3

Field surveys were conducted by trained biologists familiar with the regional flora who have familiarized themselves with the distinguishing morphologic characteristics, life cycles, and habitats of the rare plant species occurring or potentially occurring in the area investigated. Field surveys sometimes required multiple site visits when taxonomic identifications required plant parts available during other seasons ("seasonal identification") when environmental conditions were unfavorable for the growth and/or observation of a species during the initial visit or when population monitoring efforts were undertaken. Types of records produced in the course of field surveys included species lists, data sheets, maps, photos, herbarium specimens, and written reports. The following types of methods were applied in the course of field surveys and are presented in order of decreasing areal scale and increasing level of detail of data provided: exploration, systematic search, and population monitoring.

2.2.1 Exploration

Exploration is the least costly and labor intensive survey method, and is generally applied over areas on a scale of 10-1000 acres. In an exploration, landscape features frequently associated with T&E species present on the ORR are sought out and identified during the site visit, and ground coverage is skewed towards those areas most likely to yield important results. Sensitive landscape elements potentially associated with T&E species on the ORR include wetlands, springs and seeps, barrens, steep slopes, rock outcrops, sinkholes, cliffs, streams, and large unfragmented native forest tracts. In addition, some artificial habitats may be associated with T&E species: in particular, unusual disturbances, anthropogenic impoundments, and areas where woody growth is suppressed but natural vegetation dominates, such as under power lines.

2.2.2 Systematic Search

A systematic search is the method of choice when intensive disturbance is planned for a specific site, and increased documentation is required for legal purposes. A systematic search is generally applied over a scale of 1-10 acres. During a systematic search, the entire area is walked and searched for T&E plant species in a pattern of transects. This allows a more complete visual coverage of the site, taking into account topographic features (such as hills and obstacles) and existing sight range limiting conditions (such as light level, fog, and vegetation density). The surveyor develops and maintains mental search images of the potential T&E species occurring on the ORR by visiting sites where they have been found and by viewing photographs prior to the search. The surveyor also must maintain an alertness to unusual conditions or features which may signal the presence of a T&E species.

2.2.3 Population Monitoring

Population monitoring is used to provide detailed baseline population data for selected rare species. Monitoring is generally applied on a scale of less than 1 acre to 2 acres. The level of detail involved in a monitoring effort ranges from simply checking for the continued existence and reproduction of a species at a site to population estimates, direct population counts, or determination of age, size, and /or sexual structure of the population. In addition, ancillary information about the site, such as topographic position, slope, aspect, light conditions, moisture levels, disturbances, and presence of pollinators, may also be collected. 4

2.3 DOCUMENTATION

Documentation of vascular plant species occurring on the ORR was accomplished by combining specimens, photography, and the ORR vascular flora data base. Taxonomic identification of vascular plant species was performed using appropriate regional guides (Radford etal. 1968, Wofford 1989, Croriquist 1980,Krai 1983, Massey et al. 1983, Gleason 1952, Gleason and Cronquist 1991). Difficult to identify specimens and specimens which potentially represented T&E species were then referred to appropriate taxonomic experts at the University of Tennessee (UT), the Tennessee State Heritage Program, and other universities, herbaria, and museums for identification. Voucher specimens were collected as physical documentation for vascular plant species when removal of the specimen was not deemed to jeopardize the population.When collection of a voucher specimen was deemed unacceptable, a photograph was taken in its place. Voucher specimens were collected for both listed and nonlisted vascular plant species occurring on the ORR. Baseline documentation for currently non-T&E species as well as T&E species were provided, since species may be added to federal and state lists in the future. Voucher specimens were mounted on nonacidic herbarium paper, labeled with the location found, the collector's name, and the collection date, and then filed in the ORR herbarium. Species which were not vouchered through removal of a physical specimen were instead vouchered by mounting and filing a photograph of the specimen taken on-location. In addition, all T&E species were photographed on location. Photographs were supplied with ORNL Photography Department numbers, and the negatives are maintained by the ORNL Photography Department. All vascular plant species identified from the ORR were entered into the ORR vascular flora data base, along with supporting information. An explanation of the data contained in the ORR vascular flora data base, along with a printout of the data base, is provided in Appendix A.

Documentation of surveys and field sample sites for T&E species, their habitats, and associated sensitive landscape elements was accomplished through mapping using a GIS. Environmentally sensitive areas on the ORR are delineated by combining data from multiple sources to identify the extents of sensitive species, their habitats, and necessary buffer zones. Spatial data is input into the GIS through digitizing and/or use of global positioning systems. Mapped coverages of T&E plant species and sensitive habitat locations are being provided to the Oak Ridge Environmental Information System (OREIS). Access to some kinds of information (e.g., actual locations of T&E species) will be restricted. 5 3. RESULTS

3.1 SURVEY COVERAGE

During 1991-1994, approximately 12,000 acres of the ORR were surveyed for T&E vascular plants (Figure 1); summary data for 1992-1994 is presented in Table 1. During 1995 and 1996, field surveys for T&E vascular plants were conducted on approximately 2,000 acres of the ORR (Figs. 1,2). Field survey data for 1995-1996 is presented in Table 2. Approximately 14,000 acres of the ORR have been surveyed for T&E vascular plants as of May 1996. Approximately 21,000 acres of the ORR have not been surveyed for T&E vascular plant species; survey coverage gaps are shown in fig. 3.

3.2 T&E SPECIES ON THE ORR

Of the 28 listed vascular plant species identified on the ORR to date (Table 3), 18 were reported prior to 1993 (Cunningham et al. 1993, Pounds 1993), and an additional 10 were reported between 1993 and 1996. Fig. 4 shows identified point occurrences for T&E vascular plant species on the ORR based on field survey sample sites (this data should not be interpreted as indicating the areal extent of these species). T&E vascular plant species have been identified from a total of 267 sites on the ORR to date. T&E vascular plant sites identified at existing sources and field surveys prior to 1995 total 82. An additional 185 T&E vascular plant sites were identified as a result of field surveys conducted during 1995 through May 1996.

Specific locations of rare plants on the ORR are kept on file by the Oak Ridge National Laboratory (ORNL) area manager. The occurrence of T&E species within operable units (OUs) and waste area groupings (WAGs), environmentally sensitive areas, and other areas on the ORR, is presented in Table 4. Environmentally sensitive areas, including the extent of T&E plant species as currently known, their habitats, and necessary buffer zones, are shown in Fig. 5. Occurrence sites (Fig. 4) and ranges, associated rare natural communities (TNC 1995, Grossman et al. 1994), environmentally sensitive landscape elements, and appropriate buffer zones based on local topography were used to delineate environmentally sensitive areas.

3.2.1 Federal T&E Species

No federally listed vascular plant species have been found on the ORR during this survey. Four vascular plant species reported from the ORR are of "special concern" at the federal level because not enough information is currently available to determine their status; these four species were listed on the formerly used C2 federal candidate list [Aureolaria patula, Cimicifuga rubifolia, Delphinium exaltatum, Juglans cinerea (Table 3)]. Juglans cinerea has been attacked by butternut canker throughout its range; identifiable (mature) growth oi Juglans cinerea was not found on the ORR during this survey although rootstocks and sprouts which may represent this species are present.

3.2.2 Tennessee T&E Species

Twenty-eight vascular plant species that have been listed by the state of Tennessee have been reported as occurring within the current ORR boundaries to date; these species are listed in Table 3 along with their status. Two of the species, Lilium michiganense and Carex oxylepis var. 6 pubescens have been identified from the ORR in the past but were not found during this survey. Lilium michiganense may have been extirpated from the ORR by the impoundment at Melton Hill dam. Also included in Table 3 is a nonlisted vascular plant species found on the ORR, Collinsonia verticillata, which is ranked highly by The Nature Conservancy (TNC) and may be a potential candidate for listing in Tennessee.

3.2.3 Other T&E Species Which May Be Present on the ORR

The following vascular plant species listed by the state of Tennessee were reported from sites which are no longer part of the ORR: Agalinis auriculata (also listed under the formerly used federal C2 candidate designation), Gnaphalium helleri, Liatris cylindracea, and Solidago ptarmicoides. These species may be present within the current ORR boundaries but were not found during this survey. Other listed vascular plant species deemed as potentially occurring on the ORR (occurring near the ORR and/or occurring in habitat found on the ORR) which may be present on the ORR but were not found during this survey are listed in Table 5.

3.3 VOUCHERS

Over 1,100 species of vascular plants have been identified on the ORR to date (Appendix A). Approximately 983 of these species were recorded prior to 1993 (Cunningham et al. 1993). An additional 144 species were recorded and vouchered (specimens placed in the ORRherbarium)as a result of field surveys during 1992-1996 (Table 6). Other institutional herbariums (in addition to the ORNL herbarium) that maintain vascular plant voucher specimens from the ORR are listed in Appendix A. Voucher photographs of Tennessee state-listed and federal "special concern" vascular plant species and their habitats on the ORR are filed with the ORNL Photography Department. A list of voucher photographs and their ORNL Photography Department numbers is provided in Table 7.

3.4 CHARACTERIZATION ABSTRACTS

Information for the following species characterization abstracts was taken from the following sources: Radford et al. 1968, Wofford 1989, Cronquist 1980, Krai 1983, Massey et al. 1983, Gleason 1952, Gleason and Cronquist 1991, Pyne and Shea 1994a,b,c. Range information was compiled from these sources and Chester et al. (1993). A discussion by TNC (1995) of the conservation significance of ORR populations of rare plants has been quoted in the abstracts when available. Table 8 provides abbreviations for U.S. states used in these abstracts.

3.4.1 T&E Vascular Plant Species Found on the ORR

3.4.1.1 Aureolaria patula (Chapm.) Pennell

Common name: Spreading false-foxglove

Family: Scrophulariaceae

Federal status: Special Concern (listed under the formerly used C2 candidate designation) 7

Tennessee status: Threatened

Location on ORR: Bethel Valley groundwater operable unit (GWOU), K-25 GWOU, Melton Valley GWOU, NA1, NA3, NA6, NAM, NA16, NA17, NA19, NA20, NA30, NA32, NA33, NA37,NA45

Habitat: Wooded, calcareous, river and creek bluffs (Krai 1983)

Habitat on ORR: In shade on calcareous bluffs and talus slopes along the Clinch River and several tributaries (often at the edge of a lake or large stream)

Range: Central KY to north GA and AL

Tennessee counties: Anderson, Coffee, Knox, Morgan, and Roane

Description: Erect to decumbent perennial herb with stems up to 12 dm in length. Stem not glaucus somewhat hairy. Lower leaves lobed. Corolla yellow, pedicels 15 to 25 mm long, capsule glabrous

Similar species: 1. Aureolaria virginica has short pedicels (1-3 mm) 2. Aureolaria laevigata and A. flava lack hairs

Flowering date: Late July through early October

Fruiting date: October-November

Comments: Other rare or uncommon species co-occurring with A. patula on the ORR are Cimicifuga rubifolia, Diervilla lonicera, Thuja occidentalis, and a mat-forming variant of Blephilia ciliata

Threats on ORR: Habitat destruction, excessive reservoir water level fluctuations, recreational activity on river banks, and tree canopy removal. Overgrowth by kudzu, an aggressive exotic vine, threatens at least one population.

TNC ORR conservation significance: "A number of populations of this species occur on ORR. Many of these sites adjoin the Clinch River, and often occur near the water's edge. It is possible that it is being dispersed by water. Spreading false-foxglove has a small range, and is rare and scattered within it. All remaining viable populations are important to its survival."

3.4.1.2 Carex gravida Bailey

Common name: Heavy sedge

Family: Cyperaceae

Federal status: None

Tennessee status: Special Concern 8

Location on ORR: Bethel Valley GWOU, K-25 GWOU, Melton Valley GWOU, NA 32, NA 42, NA51

Habitat: Dry, open areas

Habitat on ORR: Wooded, rocky slopes

Range: Southeast ML south IA, and KS; south to TX and fiirthereas t (TN, NC) perhaps as a recent introduction

Tennessee counties: Knox, Meigs, Montgomery, and Roane

Description: An inconspicuous sedge. Difficult to identify in the field below genus level. Expert consultation is required for positive identification. May sometimes be detected in the field by noting that the fruiting culms are leaning over close to the ground and thus the common name but other Carex species may do this also.

Fruiting date: Summer

Comments: C. gravida is growing in surprisingly shady and undisturbed locations on the ORR. Radford et al. (1968) describe the species habitat in the Carolinas as waste places.

Threats on ORR: Habitat destruction

TNC ORR conservation significance: "The populations on the ORR are at the eastern limit of this primarily midwestern species. Populations peripheral to the main range of a species often indicate unusual habitats and represent unique genetic material."

Similar species: l.Astilbe biternatum is vegatatively very similar and grows in the same habitat. It is useful to look for old flowering stalks to aid the identification. 2. Other Cimicifuga have 15 or more leaflets per leaf while C. rubifolia normally has 3-9.

Flowering date: July-October

Fruiting date: September-October

Comments: Other rare species co-occurring with C. rubifolia on the ORR are Saxifraga careyana, Diervilla lonicera, andAureolaria pa tula.

Threats on ORR: Habitat destruction, tree canopy removal, invasion of habitat by competing exotic species (which may result from forest fragmentation)

TNC ORR conservation significance: "This species is scarce throughout its narrow range. 11 Important populations of this species occur on ORR."

3.4.1.6 Collinsonia verticillata Baldwin ex Elliot

Common name: Whorled horse-balm

Family: Lamiaceae

Federal status: None

Tennessee status: None

Location on ORR: BCOU4, K-25 GWOU, Melton Valley GWOU, NA39, NA41, NA44, NA45, NA52.NA54

Description: Perennial herb (2-8 dm) with upper leaves appearing whorled. Flowers are lavender, light pink, or white.

Similar species: 1. Collinsonia canadensis might be confused with C. verticillata when flowers are absent, but usually the leaves do not appear whorled on Collinsonia canadensis.

Flowering date: Late April through early June

Fruiting date: June-July

Comments: Highly ranked by TNC

Threats on ORR: Habitat loss

TNC ORR conservation significance: Not described in the ORR report

3.4.1.7 Cypripedium acaule Ait.

Common name: Pink lady-slipper

Family: Orchidaceae

Federal status: None

Tennessee status: Endangered (due to commercial exploitation) 12

Location on ORR: BCOU4, Bethel Valley GWOU, Melton Valley GWOU, HA2, HA4, HA7, NA4, NA6, NA14, NA20, NA24, NA25, NA42, NA46, NA47, RA 6, RA9

Habitat: Bogs and dry, acid pine woods (Radford et al. 1968)

Habitat on ORR: Moist to dry acid woods with pine trees

Range: East US; south to SC and AL

Tennessee counties: Perhaps in all counties of East Tennessee, but not found west of the eastern Highland Rim

Description: Two large, ribbed ovate leaves are at the base of a single flowered scape. Flower pink, fissured in front

Similar species: Cypripedium acaule is rarely white flowered, possibly leading to confusion, but the pair of large basal leaves is unique among our Cypripedium.

Flowering date: April-July

Comments: C. acaule is a showy species much prized in the wildflower trade. Evidence to date indicates that not only is the species being removed from its habitat in large numbers across the state, but also, no propagation techniques are known to be successful. For this reason, TDEC lists the species as endangered in Tennessee.

Threats on ORR: Habitat loss, tree canopy removal, and illegal digging

TNC ORR conservation significance: "The significance of ORR populations of this widespread and common species is minor. It grows in several ORR locations, mostly in moist to dry acidic woods, especially in successional pine forests. Occurrences on ORR are more protected from collection (one of the main threats to the species) than populations on private or unrestricted public land."

3.4.1.8 Delphinium exaltatum Ait.

Common name: Tall larkspur

Family: Ranunculaceae

Federal status: Special Concern (listed under the formerly used C2 candidate designation)

Tennessee status: Endangered

Tennessee counties: Anderson, Hamilton, and Roane

Description: Erect, solitary stems to 15 dm in height. Branched racemes with blue flowers late in season

Similar species: l.Aconitum uncinatum in the early stages (basal leaves) before the stem develops is very similar and should be differentiated at a later stage. 2. Other species of Delphinium which might be confused with D. exaltatum are hairy on the stem below the inflorescence.

Flowering date: August-September

Fruiting date: September-October

Threats on ORR: Habitat destruction, invasion of habitat by woody species, shade, fire suppression

TNC ORR conservation significance: "One of the largest range-wide populations of this species occurs on ORR. Several additional populations are also important to this species' survival."

Range: MA to VA; west to MN, MO, and OR; now known from TN and NC

Tennessee counties: Lake, Montgomery, Obion, and Roane

Description: Submerged aquatic with whorls of three leaves. Leaves are linear, acute, and densely imbricate at growing tips. The miniscule staminate flowers are free floating, sometimes appearing as a white powder on the surface of the water.

Similar species: 1. Elodea canadensis does not have the free floating flowers

Flowering date: July-September

Comments: No other rare species are known to co-occur with E. nuttallii on the ORR. Probably a recent introduction

Threats on ORR: Habitat destruction, draining of ponds, water temperature change, water pollution

TNC ORR conservation signiflcance: "Nuttall's waterweed has established itself at ORR in artificial ponds or embayments of the Clinch River. It may be dispersed by waterfowl. The ORR lies at the edge of the range of this species. Populations peripheral to the main range of a species often indicate unusual habitats and represent unique genetic material."

3.4.1.12 Fothergilla major (Sims) Lodd.

Common name: Mountain witch-alder

Family: Hamamelidaceae

Description: Erect, perennial herb with thick yellow rhizomes. Stems 1.5-5 dm tall. Solitary, greenish-white, epetalate flowers with numerous stamens

Similar species: None

Flowering date: April to May

Fruiting date: June-July

Comments: Hydrastis canadensis is a valued medicinal herb on both national and international markets. Like ginseng, its rarity is primarily the result of herb collectors digging the plants. Other rare species that cc—occur with H. canadensis on the ORR are Spiranthes ovalis and Lilium canadense.

Threats on ORR: Habitat destruction, unauthorized digging to remove plants, tree canopy removal, invasion of habitat by competing exotic species following forest fragmentation, erosion and siltation related to upslope timber salvage activities

TNC ORR conservation significance: "ORR populations are more protected from collection pressures (one of the main threats to the species) than populations on private or unrestricted public land. The importance of these populations needs further assessment."

3.4.1.14 Juglans cinerea L.

Common name: Butternut, white walnut

Family: Juglandaceae

Federal status: Special Concern (was listed under formerly used C2 candidate designation)

Tennessee status: Threatened

Location on ORR: Melton Valley GWOU, WAG 2, NA32 (These specimens are most likely Juglans cinerea L., but they cannot be confirmed because of immature specimen growth.)

Habitat: Rich woods

Habitat on ORR: Slopes near major streams

Range: New Brunswick to Ontario; south to MI and ND; south to VA, GA, AR, and KS

Tennessee counties: Anderson, Blount, Campbell, Carter, Chester, Cooke, Cumberland, Franklin, Hamilton, Hawkins, Hickman, Houston, Lewis, Monroe, Polk, Roane, Sevier, Stewart, Sumner, Tipton, Van Buren, Wayne, and Williamson

Description: A walnut tree that can be distinguished from the common black walnut by its 18 elongated fruit (ellipsoidal vs. spherical) and smoother bark. Pith color and hairiness above the leaf scar characteristics appear to be difficult to apply.

Similar species: see "Description" and "Comments"

Flowering date: April-May

Fruiting date: October

Comments: Butternut was previously listed under formerly used C2 candidate designation by the U. S. Fish and Wildlife Service (USFWS) because of the threat of a fatal disease— butternut canker. We have observed no nut production in butternut on the ORR. The identification of walnut species at two locations is in question. The identification of these young trees was based on pith color, which may not be reliable. The ORRherbarium has a specimen from 1965. M. W. Bierner verified the identification in 1974. There is a possibility that Manchurian walnut has been introduced on the ORR. It could be confused with the other two species of walnut.

Threats on ORR: Habitat destruction, cutting

TNC ORR conservation significance: "The importance and health of these populations needs additional assessment. Reproducing populations are extremely rare."

3.4.1.15 Juncus brachycephalus (Engelm.) Buchenau

Habitat: Fens

Habitat on ORR: Open wetlands

Range: ME to northern Ontario and WI, south to PA, OH, and IN. Disjunct in TN.

Tennessee counties: Cheatham, Claiborne, Humphrey, Lewis, Maury, Roane, Warren, Wayne

Description: Rushes are grass-like plants. This species bears mature fruits after the other rushes on the ORR

Fruiting date: Late July, Aug., possibly Sept.

Threats on ORR: Habitat destruction fromprojec t development, hydrologic regime change, and at one site, possible disturbance related to the adjacent highway 19 TNC ORR conservation significance: "This species is very rare in Tennessee. The ORR population is one of very few known in the Ridge and Valley Province of Tennessee. Populations peripheral to the main range of a species often indicate unusual habitats and represent unique genetic material."

3.4.1.16 Lilium canadense L.

Common name: Canada lily

Family: Liliaceae

Tennessee counties: Anderson, Campbell, Claiborne, Cumberland, Davidson, DeKalb, Johnson, Montgomery, Morgan, Overton, Putnam, Roane, Rutherford, Scott, Sevier, and Stewart

Description: Stems to 20 dm tall with whorls of 5-11 leaves. Flower segments are yellow-orange to red, spotted, and slightly recurred to spreading. Petals and sepals more than 6 cm long

Similar species: 1. Lilium michiganense is very similar but can be distinguished when in bloom. Lilium canadense has anthers held close together, barely, or not at all exerted from the only slightly or moderately recurved tepals rather than anthers well separated on strongly divergent filaments with the tepals strongly recurved-reflexed. 2. Lilium superbum has smooth leaf margins rather than spiculate-scabrous.

Flowering date: June-July

Fruiting date: July-September

Comments: This species is very similar vegetatively to and may be confused with Lilium michiganense, which is also a Tennessee state-listed threatened species. These native lilies rarely bloom on the ORR. It is possible that the populations which have not been seen to flower include Lilium michiganense.

Threats on ORR: Digging up for transplanting, habitat destruction, indiscriminate use of herbicides, fire supression 20

TNC ORR conservation signiflcance: "Occurrences on ORR are more protected from collection (one of the main threats to the species) than populations on private or unrestricted public land. Wetlands in the Ridge and Valley Province are rare and often in poor condition, while those on the ORR are in better condition. Populations peripheral to the main range of a species often indicate unusual habitats and represent unique genetic material."

Tennessee counties: Virtually all counties

Description: Glabrous, perennial herb arising from tuberous roots. Stems erect, 1.5-6 dm tall. Petiolate, palmately compound leaves in a whorl at apex of the solitary stem

Flowering date: May-June

Fruiting date: August-October

Comments: Ginseng is prized in this country and abroad for its reputed medicinal properties and is highly sought by herb collectors. Its rarity in Tennessee is the result of commercial exploitation. Tennessee state law specifies a harvest season (August 15-December 31) and landowner permission to dig ginseng (ginseng berries should be replanted on site).

Harvesting of ginseng in Tennessee:

According to the "Ginseng Harvest Season Act of 1985" (Acts 1985, Ch. 177,1; Tennessee Code Annotated 11-26-101) it is unlawful in Tennessee for any person to dig, harvest, collect or remove wild ginseng from any land for the purpose of sale or export under the following circumstances:

(a) On any date not within the ginseng harvest season (harvest season is Aug. 15-Dec. 31) (b) Plants with green berries or less than three prongs (c) To remove the berries of wild ginseng from the approximate location harvested (d) Plants that were harvested from any state other than Tennessee unless such ginseng has been approved for export by the state from which it was harvested (e) Without permission of the landowner

Penalties for violation of this law, upon conviction, are a fineno t to exceed $250 and forfeiture of all ginseng harvested, collected, removed, or sold in violation of the law.

Ginseng dealers must be registered and obtain a permit from the Department of Environment and Conservation, 701 Broadway, Nashville, Tennessee 37243. Monthly records and an annual report must be filed with this department. Dealers exporting ginseng from Tennessee must attach a Tennessee ginseng export certificate with each sale of roots.

Threats on ORR: Digging to remove plants, habitat destruction, and tree canopy removal. There has been a recent (1995) increase in the price of ginseng; this may increase the demand and the frequency of poaching.

TNC ORR conservation significance: "Ginseng occurs sporadically across ORR lands. ORR populations are more protected from collection pressures (one of the main threats to the species) than populations on private or unrestricted public land. The importance of these populations needs further assessment. Populations on ORR are probably able to maintain a normal age structure." 23 3.4.1.20 Platantheraflava var. herbiola (R.Br.) Luer

Common name: Tubercled rein-orchid

Family: Orchidaceae

Federal status: None

Tennessee status: Threatened location on ORR: BCOU4, Melton Valley GWOU, NA4, NA13, NA28, NA48, NA50, NA52 Habitat: Alluvial woods, wet meadows, and marshes (Radford et al. 1968)

Habitat on ORR: Forested wetlands and wet meadow site

Range: Nova Scotia to southern Ontario; central MN; south to MO; east to mountains of NC, VA, andTN

Tennessee counties: Anderson, Campbell, Cocke, and Roane

Description: Erect, glabrous plant with lanceolate leaves sheathing the stem, reduced to bracts on upper stem. A spike of yellow-green flowers on stems to 5 dm in height. Floral bracts much exceed the flowers

Similar species: 1. Platantheraflava var. flava (also state listed) is not as leafy in the inflorescence.

Flowering date: May-August

Comments: Variety herbiola is the northern variety of P. flava and is more rare in Tennessee than the southern variety, flava. It is noteworthy that the Bear Creek wetland and Hembree Cemetery marsh both support typically northern taxa that are rare in Tennessee. Liparis loeselii, the northern counterpart of'Liparis lilifolia, occurs in the forested wetland adjoining Hembree Cemetery marsh.

Threats on ORR: Habitat destruction, change in hydrologic regime (draining or flooding), and tree canopy removal

TNC ORR conservation significance: "This variety grows in several ORR wetlands; these occurrences are the largest known in Tennessee. ORR occurrences are at the southern range periphery and may represent unique genetic material. Wetlands in the Ridge and Valley province are rare and often in poor condition, while those on the ORR are in better condition."

Flowering date: July-September

Fruiting date: August-October

Comments: This confusing species cluster includes three rare and difficult to separate species of Pycnanthemum: P. verticillatum, P. virginiana, and P. torrei. Expert consultation is required for positive identification. Pycnanthemum verticillatum has not been identified recently in Tennessee and was listed as possibly extirpated. Pycnanthemum torrei has been identified in Tennessee only from a recent collection at one site in Oak Ridge. Both P. verticillatum (in the broad or narrow sense) and P. torrei are very rare in Tennessee. Pycnanthemum virginianum is not currently listed by the state but is also considered rare in Tennessee (personal communication, Paul Somers, TDEC, to L. Pounds, ORR Research Park, 1989).

TNC ORR Conservation significance: This species was not described in the ORR report.

Similar species: 1. R. strepens has wider calyx lobes (2mm or more). 2. R. humilis has shorter petioles (3mm or less). 3. R. Carolina has two sides of the stem hairier than the other two.

Flowering date: June-August

Comments: Taxonomic problems may exist within this genus (Ruellia) 27

Threats on ORR: Habitat destruction

TNC ORR conservation significance: This species was identified on the ORR after the ORR report

3.4.1.25 Saxifraga careyana A. Gray

Common name: Carey saxifrage

Family: Saxifragaceae

Federal status: None (was listed under the formerly used 3C candidate category)

Tennessee status: Special Concern

Location on ORR: NA1, NA3, NA5, NA11, NA15, NA16, NA17, NA18, NA21, NA23

Habitat: Moist rocks and seepage slopes (Radford et al. 1968)

Habitat on ORR: Rocky, calcareous bluffs and sinks along the Clinch River

Range: GA, MA, NC, PA, TN, and VA

Tennessee counties: Anderson, Bledsoe, Blount, Carter, Cocke, Franklin, Grainger, Hamilton, Hancock, Knox, Loudon, Marion, Monroe, Pickett, Polk, Rhea, Roane, Sevier, Sullivan, Unicoi, and Van Buren

Description: Small, perennial herb forming rather fleshy rosettes and short offsets from the crown. Hairy leaves are slightly concave on the upper surface, rounded and frequently reddish on the underside. White to pale-pink flowers with scapes up to 3 dm tall

Similar species: 1. S. caroliniana is similar but it has clavalate filaments

Flowering date: April-June

Fruiting date: May-June

Comments: The taxonomy of S. car ey ana and S. caroliniana is confusing, so much so that the species have been called "the careyana-caroliniana complex." S. caroliniana is a federal "Species of Concern" (listed under the formerly used C2 candidate category) and is listed as endangered in Tennessee. Some of the populations on the ORR have not been surveyed in the flowering stage, a stage necessary to distinguish the two species. Saxifraga caroliniana is not reported to occur in the Ridge and Valley Province in eastern Tennessee, so these populations are most likely S. careyana. Rare species that co-occur with S. careyana on the ORR are Aureolaria patula, Cimicifuga rubifolia, and Diervilla lonicera.

Threats on ORR: Habitat destruction, tree canopy removal, erosion and siltation related to upslope timber removal or development 28

TNC ORR conservation significance: "ORR represents an important concentration of populations of this narrowly distributed endemic."

4.1 FOLLOW-UP SURVEYS

4.1.1 Future Surveys at Environmental Restoration Remediation Sites

Systematic T&E vascular plant surveys are necessary prior to initiation of remediation or other project activities at a site when any of the following conditions apply:

• The area has never been surveyed using systematic ground coverage. • The area has not been surveyed in multiple seasons. • The area has not been surveyed within 5 years prior to the commencement of activities at the site.

( 4.1.2 Additional Surveys

Follow-up surveys maybe required in the future. Follow-up surveys for T&E vascular plants are recommended for the following reasons:

• Detailed T&E vascular plant surveys (which include systematic ground coverage and multiple season site visits) have not been performed for large areas of the ORR. The existence of additional sites for T&E vascular plant species, which were not detected during this survey, is likely. • Additional species (not investigated in this survey) may be added to state and federal lists in the future. • Under certain environmental conditions, some rare plants, including T&E species that have been found on the ORR, may undergo prolonged periods of dormancy in which the individual or population exists for many years either as rhizomes (underground) or as propagules in soil seedbanks. Such species may not have been detected during this survey and may "re-appear" after extended intervals. • Plants, including T&E species, will sometimes occur in atypical habitats. An example of a rare taxon occurring in an atypical habitat on the ORR is heavy sedge (Carex gravida), a prairie species typical of open sites, which has been found at two forested sites on the ORR. Rare taxa in atypical habitats may be less likely to be discovered because (1) the habitat is not identified during the initial survey as potential habitat for the taxon, (2) the field botanist might not be using that particular search image if the taxon is not expected to occur in the habitat, or (3) the taxon might have an unusual growth form because of habitat location and thus differ from the botanist's search image.

4.2 MAINTENANCE AND UPDATE OF DATABASES AND VOUCHER COLLECTION

The following data generated during this project will be submitted to OREIS:

• Sample point locations for T&E vascular plant species (GIS coverage) • ORR environmentally sensitive areas (GIS coverage) 38

• T&E vascular plant survey coverage data (GIS coverage) • ORR vascular flora data base (spreadsheet data) Data bases and collections documenting T&E species on the ORR that are not submitted to OREIS (because they do not fit OREIS data requirements) are also valuable resources. Readily available access to updated T&E data sources would facilitate future compliance with environmental regulations. Specifically, the following resources should be maintained:

• Voucher specimen collection (ORNL herbarium) • T&E photographic collection (negatives maintained by ORNL Photography Department) • ORR. Heritage data base (maintained by ORNL area manager)

4.3 AVOIDANCE OF ORR ENVIRONMENTALLY SENSITIVE AREAS

Protection of T&E species in their natural habitats is the most effective method of ensuring their long-term survival. ORR environmentally sensitive areas include T&E species and their habitats, sensitive landscape elements and rare natural communities associated with T&E species, as well as necessary buffers. Project planners should seriously consider avoiding altogether or taking extra precautions in areas designated as ORR environmentally sensitive areas (Fig. 5).

4.4 IMPACT ASSESSMENT 4.4.1 Scale of Concern

Impacts to T&E species on the ORR should be considered at both local and regional scales. Impacts to sensitive species and natural communities on the ORR may have regional consequences. Although the original forests had been cleared, and the land was in agriculture at the time the ORR was purchased by the U.S. government in 1942, much of the ORR has been relatively undisturbed since 1942, and many areas have been allowed to undergo natural succession. In contrast, the land surrounding the ORR has either remained in agriculture or been developed for commercial, industrial, and residential purposes. As a result, the natural vegetation on the ORR has become increasingly significant in relation to regional biodiversity. TNC reports that ORR natural habitats "provide a refuge for many plants, animals and natural communities that are disappearing from surrounding lands..." (TNC 1995). This significance is evident in the significant number of T&E vascular plant species (Table 3) and rare natural communities (TNC 1995; Grossman, Goodin, and Reuss 1994) found on the ORR. One T&E plant species on the ORR (Rhynchospora colorata) is currently known from no other location in the state of Tennessee.

4.4.2 Threats to T&E Vascular Plant Species

Project activities on the ORR may have the potential to adversely impact T&E species both directly and indirectly. Adverse impacts to T&E plants, both to T&E plants on site (direct) and to T&E plants off site (indirect) may occur on the ORR as a result of:

• predevelopment site monitoring and characterization activities; • installation of equipment (for monitoring or infrastructure); 39 use of earth-moving equipment; road building; site preparation, grading, and landscaping; construction of facilities; disposal of waste materials; alteration of hydrologic regime (drainage of water or flooding); timber removal; mowing; and pesticide application.

Direct threats to T&E plants include removal, burial, poisoning, or otherwise physically damaging the plants themselves, and direct disturbance or destruction of their habitats. Indirect impacts to T&E species occur as a result of project activities but do not involve direct contact or interference with the plants themselves. Indirect threats to T&E plants include the following.

• Habitat fragmentation: loss of landscape connectivity between areas of natural habitat. Habitat connectivity may be necessary to allow genetic exchange between populations or to support or allow access to the habitat by animals which carry the seeds. • Creation of disturbed openings and additional forest edges: these openings provide an entry route for the invasion of T&E species habitats by competing weedy species. • Planting of aggressive or persistent exotic (also known as "non-native" or "introduced") species (for erosion control, site stabilization, reforestation, landscaping, etc.): exotic species may subsequently migrate from the target site and compete with T&E species. Over 190 species of vascular plants that are not native to this region have been found growing wild on the ORR to date. Exotic plant species currently associated with adverse impact to T&E species or have a high potential to adversely impact T&E species are listed in Table 9. • Exposure of T&E plants to damaging agents (including insect pests, diseases, grazing by deer, and picking or digging of plants by humans) as a result of increasing access to the site. • Reduction of pollinators (through loss of supporting habitat or poisoning): loss of pollinators may result in reproductive failure in the plant species. Many types of insects, and some birds and mammals (such as bats) may act as plant pollinators. • Creation or loss of shade: plant species are adapted to growth under particular light levels, and within particular microclimates. Changes in light level directly affect a plant's ability to photosynthesize and grow and drive other changes in the site microclimate such as increasing dryness or humidity. Such changes may allow competing weedy species to invade the site. • Fire suppression: some T&E plant species, particularly those associated with calcareous barrens, may require fire to maintain their habitat open. • Changes in maintenance activities in T&E plant zones (such as those within utility corridors and hay fields): timing of mowing and/or other maintenance activities to avoid blooming and fruiting periods may be critical to the survival of populations of T&E plants in maintained areas. 40

Erosion and/or siltation resulting from up-slope activities (including facility maintenance, timber removal, and excavations): adverse impacts of site runoff and sediment movement to nearby T&E plant may include burial, drowning, root exposure, scouring, or up-rooting. Chemical changes: input or diversion of nutrients may adversely affect sensitive species. 41 REFERENCES

ration (May 1996) Appendix C ORR VASCULAR FLORA DATA BASE

C-3

THE ORR VASCULAR FLORA DATA BASE

This species list is a revision of List 1 in Appendix E of the Resource Management Plan for the Oak Ridge Reservation, Volume 29: Rare Plants on the Oak Ridge Reservation (Cunningham et al 1993). More than 100 additional species have been found on the ORR since 1985. Some species listed man unpublished report by the Tennessee Valley Authority (TVA) (1950-1953), An Ecological Survey of White Oak Creek on the White Oak Creek, do not appear on the current ORR list because research park staff were unable to locate the corresponding herbarium specimens for verification. These specimens are presumed to have been refiled since they were not found under the species names used in the report Refiling normalry indicates a change in identification. No attempt was made to find the new location of a specimen, i.e., its new identification.

Data base field descriptions:

FAMILY, GENUS, SPECIES, VARIETY

The scientific names (genus, species, variety and family), are primarily taken from Wofford and Krai (1993). A few taxa are not referenced in this source; other sources were used for these scientific names, and these taxa are indicated in the COMMENTS field. The other sources are Gleason and Cronquist (1991) and Radford, Ahles, and Bell (1986).

Some taxa do not meet criteria for inclusion in the ORR flora but have been included in the data base to clarify their status; these ineligible SPECIES are marked with an asterisk (*). The ELIGIBILITY field indicates why these taxa are not included in the ORR flora.

SYNONYM

In some cases synonyms for scientific names are given which might be more familiar to the user than those chosen by our sources. If the synonyms differ only as to genus, then only genus is given in the synonym column.

COMMON NAME

The principle sources used for common names were Great Smoky Mountain Natural History Association and Gleason and Cronquist (1991). A standard list of common names is expected to be published soon by John T. Kartesz and Rosemarie Kartesz. This list may be used in future versions of this data base.

ELIGIBILITY (ORR FLORA)

The data base contains some taxa which are not eligible for inclusion in the ORR vascular flora but have been retained in the data base to clarify their status; these SPECIES are marked with an asterisk (*). The column headed ELIGIBILITY indicates why these taxa are not included in the ORR flora:

• el = meets criteria for membership in ORR flora (see note below) • ne (not established) = exotic taxon fromhorticultur e which has not yet shown that it can survive without horticulture C-4

• qr (questionable report) = questionable report of the taxon hy (hybrid) = a hybrid that does not seem to be established independently of parent species • id (identification) = the identification is questionable • tax (taxonomy) = there may be confusion in the taxonomy • pi (previous list) = on Mann, Patrick, and De Slem. (1985) {A Checklist of the Vascular plants of the Department of Energy Oak Ridge Reservation), but currently we do not have evidence in the form of a specimens or a confident report from a botanist for the occurrence of the taxon on the ORR • ot (ownership transferred) = the location where the taxon was found is outside the current ORR boundary (the ORR boundary has changed due to the transfer of "surplus" land) • nt (new taxon)=the taxon has recently been described, and is likely to occur on the ORR, but there has not yet been a search for it

Note: The following criteria must be met for inclusion in the ORR vascular flora:

1. The taxon is a vascular plant. 2. Verification exists (see PROOF) that the taxon occurs within the ORR boundaries as of October. 1995. Verification includes herbarium specimens, photographs, and confident reports of botanists. We are in the process of obtaining specimens in cases where the only verification is a confident report. 3. The taxon appears capable of maintaining itself indefinitely without horticultural support (a natural occurrence). The list does not include many of the taxa currently used for plantings around buildings, or taxa which were planted originally at homesteads but are gradually dying out as the homestead sites return to natural vegetation. 4. The taxonomic identification of the specimen is accepted. The identification of a specimen may be tentative in several ways: (1) the quality of the available specimen is inadequate, (2) a botanist with expertise in the taxa and able to confirm the identification has not yet been located; (3) the material cannot be clearly identified because it may represent plants unidentifiable by available taxonomic literature, e.g., the material is from a hybrid, diseased, or undescribed plant. 5. The taxon is valid; for example, a taxon may be invalid if it is distinguished from other taxa based on environmentally determined (rather than genetically) determined characters. We try to follow expert opinion as to validity, but the experts do not always agree.

PROOF

This column lists the verification for the occurrence of each taxon on the ORR:

• ORRH=specimen in the ORR herbarium • ORRHv = only specimen stored in the ORR herbarium vault ORRHs=specimen in a special collection at the ORR herbarium (not filed with general specimens) • UTK = specimen in the UTK herbarium • US = specimen in the Smithsonian Institute herbarium C-5

• DU=specimen in the Duke University herbarium • P = photographs in the ORR Environmental Research Park office and in the herbarium • r (report) = reported with confidence by a botanist

CONTAMINATED

This column indicates taxa that have a specimen sequestered in a vault adjacent to the ORR herbarium at Bldg. 0907. These specimens are contaminated with radioactive material. c = contaminated

COMMENTS

This field indicates species which are not included in Wofford and Krai (1993), a source which attempts to list all species naturally occurring in Tennessee. The source used for these species is given in this field. This field also indicates species which are rare in Tennessee and/or East Tennessee (east of the central basin) based on range maps in Chester et al. (1993) and unpublished range maps kept in the University of Tennessee herbarium.

TN NATIVE, VS. EXOTIC

This column indicates whether the taxon is considered to be native or exotic in Tennessee according to Wofford and Krai (1993). Wofford and Krai do not define native in this 1993 work. Native to Tennessee might be defined as occurring naturally in Tennessee previous to the influence of European culture and not solely in Native American cultivation. Taxa may be native to Tennessee but not to East Tennessee, e.g., bald cypress; such taxa are not differentiated in the data base. In many cases direct evidence of pre-European occurrence is lacking, and the conclusion is a best guess. Exotic is taken to mean not native. Aggressive vs. passive was determined based on the field experience of ORR Research Park botanical staff.

• nat = native to TN (may not be native to the ORR) • ea = (exotic aggressive), observed to exclude native species on the ORR • ea? = (exotic aggressive questionable), not yet observed to exclude native species but has characteristics that make it likely to become a problem in the future • ep = (exotic passive), not observed to exclude nor expected to exclude native species • ep? = (exotic passive questionable), not observed to threaten native species, but information is lacking • e = (exotic), no information on the threat to native species

FREQUENCY (ORR)

This field indicates the approximate frequency of occurrence of each taxon on the ORR as estimated by research park staff based on field experience. Except for rare species, frequencies for taxa are subjective. Question marks are used with the codes to indicate a higher degree of uncertainty. The frequency codes are a modification of those used by the Great Smoky Mountains Natural History Association (no publication date) in Flowering Plants of the Great Smoky Mountains National Park. C-6

• c = (common) found regularly in common habitats • f = (frequent) found somewhat irregularly in common habitats • o = (occasional) found at 14-20 sites • i = (infrequent) found at 9-13 sites • s = (scarce) found at 4-8 sites • r=(rare) found at 2-3 sites or at one site with more than 20 individuals • vr=(very rare) found at 1 site with less than 20 individuals • ? = (status uncertain) higher than normal level of uncertainty

TN STATUS

This column lists the status assigned to the taxon by TDEC. Codes and code assignment to species are taken from an unpublished TDEC list (1994).

TNcode:

• S = special concern • T = threatened • E = endangered • E* = endangered due to commercial exploitation • P = possibly extirpated from Tennessee [records are historical (not current)]

U.S. STATUS

This column lists the status assigned to these taxa by the FWS (1993).

• C2 = a second priority level candidate for federal listing under the Endangered Species Act (currently called species of concern) • 3C = a species which was a candidate for listing but did not achieve listing and is no longer considered a candidate for listing

R2IND (WETLAND INDICATOR STATUS)

The FWS (Reed 1988) has developed a classification system that assigns species to wetland indicator classes according to the frequency with which these species occur in a wetland. These indicators are used to establish the hydrophytic vegetation criterion for identification and delineation of jurisdictional wetlands (U.S. Army Corps of Engineers 1987). "R2IND" refers to the indicator (IND) that has been assigned to the species in EPA Region 2 (R2), which includes most of the southeastern U.S. A species which is considered to be an upland species in all regions of the U.S. is not included on mis list This creates a problem in interpreting mis list because species found on the ORR and not found in Reed (1988) may be upland or not treated by Reed and thus may have a status other than upland. In these cases, a judgment was made by research park staff. If the species appeared to be an upland species, it was given that code in the column. If not, a question mark (?) was placed in that column, and in some cases a wetland indicator code was given by the staff for the species as seen on the ORR in another C-7 column (ORRIND). In a few cases observations on the ORR did not agree with the indicator code assigned by Reed. These disagreements are indicated by an alternative indicator codes in the ORRIND column.

ORRIND (ORR alternative wetland indicator)

If a species is not listed in Reed (1988), it is generally assumed to be an upland species. If the species appears to exist in only xeric, upland situations on the ORR, the UPL indicator was placed in the R2IND column. However, some of these species have routinely been found in wetland conditions on the ORR. In this case a question mark has been placed in the R2IND column, and in the ORRIND column has been placed an unoffical indicator status for the species based on the professional judgment of the research park staff The ORRIND column also includes alternative indicators for some species for which field observations were not in agreement with the indicator listed by Reed. The ORRIND column should be considered preliminary and should not be used in conducting wetland determinations.

These codes and their assignment are taken from Reed (1988) except for ? and in some cases for UPL (see previous paragraph). Percents indicate the probability that the species will occur in a wetland (wetland fidelity or frequency).

• UPL(upland) = < 1% wetland fidelity. • FACU (facultative upland)=wetland fidelity in the range 1-33% • FACU- (facultative upland -) = wetland fidelity in the lower part of the range 1-33% • FACU+ (facultative upland +) = wetland fidelity in the upper part of the range 1-33% • FAC (facultative) = wetland fidelity in the range 34- 66% • FAC- (facultative -) = wetland fidelity in the lower part of the range 34-66% • FAC+ (facultative +) = wetland fidelity in the upper part of the range 34-66% FACW (facultative wetland) = wetland fidelityi n the range 67-99% • FACW- (facultative wetland -) = wetland fidelityi n the lower part of the range 67-99% • FACW+ (facultative wetland +) = wetland fidelity in the upper part of the range 67-99% OBL (obligate)=>99% wetland fidelity • NI (no indicator) = no indicator was assigned because of insufficient information NO = not believed to be found in Region 2 by Reed • NA = no indicator status assigned because of lack of agreement among those polled • ? - the taxon was not found in Reed (1988), but it does not appear to be an upland species (UPL) C-8

ADDITIONAL DATA FIELDS

The following data fields are not included in this appendix but are available in the complete data baseonOREIS.

TAXONOMC GROUPING

Taxa are broken down into the following general groups:

• fern ally • fern • gymnosperm • monocot • dicot LIFESPAN

This field indicates whether a species is an annual, biennial, perennial, or a combination of these. Information was compiled fromth e Soil Conservation Service, Gleason and Cronquist (1991), and the national PLANTS data base (USDA, NRCS 1995). Where the Soil Conservation Service (1982) and Gleason and Cronquist (1991) disagreed, information from Gleason and Cronquist was used with a question mark. In a few cases no information was available from these sources, and only a question mark was used for the code. Reproductive schedule within a species may vary with variety, seasonal weather conditions, and/or geographical region.

• annual = a plant that reproduces and dies after 1 year (one reproductive period) • biennial = a plant that reproduces and dies after 2 years (one reproductive period) • perennial = a plant that lives more than 2 years (usually more than one reproductive period)

STRATA

This column separates herbaceous (coded as grasslike or forb) plants from woody plants and divides the woody plants by growth form. The classification of woody plants used in Trees of the Great Smoky Mountains (Great Smoky Mountains Natural History Association, no publication date) has been followed with an additional code (h, hemishrub) taken fromUSD A (1982).The decision as to which code to use for a species was influenced by observations on the ORR.

• ct = canopy tree • ut=understory or small tree • sh = shrub • ss (sub-shrub) = very small shrub (normally less than 30 cm high and often not of typical shrub form) • wv = woody vine C-9

• hs (hemishrub) = some woodiness at the base of the plant (suffrutescent) • gr (grasslike) = a grass, sedge, or rush • fo (forb) = an herbaceous plant that is not grasslike (G) nor a vine (V) • vi = an herbaceous vine

SYMBIOSIS

This column indicates plants with special features. Information was compiled from the Soil Conservation Service (1982), Gleason and Cronquist (1991), and the national PLANTS data base (USDA, NRCS 1995). Where the Soil Conservation Service and Gleason and Cronquist disagreed, information from Gleason and Cronquist was used with a question mark.

• epiphyte=a plant growing on a tree which does not have roots in the ground nor in the living part of the tree (e.g. mistletoe is not considered to be an epiphyte but rather a parasite) • parasite=a plant that gains all or a significant amount of its nutrition from another vascular plant by root penetration • mycotroph=a plant that gains most of its nutrition from association with a fungus (in certain cases loosely called saprophytic)

AQUATIC HABIT

This column indicates plants with special features. Information was compiled from the Soil Conservation Service (1982), Gleason and Cronquist (1991), and the national PLANTS data base (USDA, NRCS 1995). Where the Soil Conservation Service and Gleason and Cronquist disagreed, information from Gleason and Cronquist was used with a question mark.

• submersed = a plant that is normally entirely, under water • emergent = a plant normally growing in water with part of the plant above the water • floating = a plant normally-growing in water with part or all of the plant floating at the water surface (some are rooted in soil below the water) C-10
