INTRODUCTION

The goal of the project was to produce verified inventories of vascular plant species (including ferns and fern allies) by unit in the Big Thicket National Preserve (BTNP), a part of the National Park System located in southeastern Texas in Hardin, Tyler, Polk, Liberty, Jefferson, Orange and Jasper counties. Collection efforts focused on the major units (Big Sandy, Hickory Creek, Turkey Creek, Beech Creek, Lance Rosier, Neches Bottom/Jack Gore Baygall, Beaumont). Owing to time constraints collecting in Loblolly Unit and Menard Creek was minimal, and no new collecting was done in the other corridor units (Pine Island Bayou, Upper Neches, and Lower Neches). Between June 2001 and December 2006, a database of 8095 specimen records was compiled. The database contains 1384 valid names representing 1264 distinct taxa in 536 genera and 146 families . From the database, final species and specimen tables were generated. A total of 7198 specimens were delivered to Dale Kruse, Curator, Tracey Herbarium at Texas A&M University (TAES) on April 6, 2007. In this report we describe methods used in constructing the database, the collectors, and the unit-level collection efforts. A species-by-unit table is presented; collection results are compared with Watson (1982), and there is an examination of variation in species richness among units.

METHODS Presence of species in units of the Big Thicket National Preserve was verified by collecting new specimens or by creating records from some existing specimens deposited at SBSC and TEX-LL or stored at Rice University. Information on collectors and collecting effort is given following the descriptions of database and table construction.

Database construction All records for new and existing specimens were managed in a taxonomic database (BIOTA ). We also entered a list of species of probable occurrence in Big Thicket National Preserve (Watson 1982, hereafter referred to as GW) . We used the list as a collecting guide, recognizing that since it was not documented by actual herbarium specimens, not all taxa on the list would necessarily be found because of possible mis- identifications or mis-attributions . In the data entry process, each specimen record was given a unique specimen code that consisted of the initials of the collector and the collector’s specimen number. Additional information entered included species code (first four letters of genus and species names), full species name, collector, collection date, habitat, location, and GPS location (where available). Species nomenclature was standardized to Kartesz and Meacham (1999), and a list was made of cases in which many authorities prefer alternative names (Appendix Table 3). To maintain taxonomic consistency, all newly- collected specimens and all but a few specimens deposited at TEX-LL were determined and annotated by Larry Brown, the authority on flora of southeast Texas. Determination history was retained by BIOTA. For specimens collected as part of this project, the depository field was coded as TAES (Tracey Herbarium at Texas A&M University, College Station, TX). For specimens that already existed in other collections, the depository field was coded as follows: SBSC Spring Branch Science Center Herbarium, Spring Branch ISD, Houston, TX. RICE Rice University, Houston, TX. TEX University of Texas Herbarium, Austin, TX LL Lundell Herbarium at University of Texas ATSC Stephen F. Austin State University Herbarium, Nacogdoches, TX

All of the above except RICE are registered herbaria.

Specimen table. For this report, records of specimens in BTNP were exported from BIOTA into a specimen table in EXCEL format containing 8095 records. From this, a new EXCEL workbook was created by adding fields for many of the variables required for input into

- 2 -

NPSpecies and breaking up the dataset into three parts, each as a separate spreadsheet in the workbook, as follows:

name number description TAES 7198 specimens delivered to TAES vrecords 55 records of specimens in other herbaria that are the only record of that species in that unit Other 730 records of specimens in other herbaria that duplicate TAES or vrecords

Subsequently, a fourth spreadsheet was added:

GWX 84 GW specimens delivered to TAES that were collected outside NPS boundaries. ____ Total records 8067

Some specimens in the Rice University Reference Collection that duplicated other collections were retained at Rice. All other specimens were delivered to TAES for subsequent selection of specimens to be given NPS accession numbers. Specimens not accessioned will either be retained as part of the TAES collection or deposited at the Big Thicket National Preserve Field Research Station, Saratoga, TX

Species table For this report, a list of all taxa known to exist within the boundaries of BTNP was exported from BIOTA. Residency status (native vs non-native) was obtained from Kartesz & Meacham (1999). Abundance by unit was calculated by converting the abundance-by-unit scores in Watson (1982) using eight abundance classes (-4 to +4), which she determined "arbitrarily by personal observation and experience." The abundance classes were converted to NPS abundance classes as follows: NPS abundance class GW abundance value Abundant +4 +3 Common +2 +1 Occasional -1 -2 Rare -3 -4

Fields were also added for many of the variables required for input into NPSpecies, including nativity (obtained from Kartesz & Meacham 1999). The species table may be linked to the specimen table using the SpeciesCode variable.

RESULTS Collectors The specimen record dataset contains the names of 22 collectors in various combinations. The collectors and their contributions are described briefly below. Geraldine Watson spent many years botanizing in the Big Thicket, guiding and working with many professionals, most notably D.S. Correll, senior author of Manual of the Vascular Plants of Texas (Correll & Johnston 1970) and Geyata Ajilsvgi, author of Wildflowers of the Big Thicket (Ajilvsgi 1979). In the late 1970s and early 1980s Watson was employed as a botanist in Big Thicket National Preserve, during which time she produced a record of species occurrences by unit (Watson 1982) amounting to nearly 7000 records for about 1300 species. This is the most complete inventory ever done for BITH, but it was not fully vouchered; only about 1000 specimens were collected. The specimens were stored at Lamar University until 2001, when they were loaned by NPS to Rice University for this project. They were subsequently transferred to The Tracey Herbarium at Texas A&M University. Investigators from Rice University engaged in ecological research from 1972 through 2006, and in the process, many specimens from BTNP were placed in the Rice University Reference Collection, by Paul A. Harcombe, Professor, (1972-2007), Donna R. Streng graduate student, (Hickory Creek, 1976-1980), and Changxiang Liu, graduate student, (Hickory Creek, Turkey Creek and Lance Rosier, 1996-1999). Most were subsequently duplicated by new collections made as part of this project, and so were retained at Rice University. Warren Pruess and I.Sandra. Elsik, Rice University research staff, collected specimens in Lance Rosier, JackGore-Neches Bottom, Beech Creek, Big Sandy, Turkey Creek and Loblolly mostly in 2004-2006. A few student collections were also made. Brooke Wheeler, a research assistant, collected 2 specimens. Katie Caldwell collected 150 specimens as part of a restoration study in the Turkey Creek Unit.

Michael and Barbara MacRoberts, Herbarium, Louisiana State University in Shreveport, studied savanna wetlands in the late 1990s (MacRoberts & MacRoberts 1998), collecting primarily in the Lance Rosier, Hickory Creek and Turkey Creek units. The Lance Rosier specimens were deposited at TEX (see MacRoberts & MacRoberts 1998). The MacRoberts subsequently completed a study of the Hickory Creek Savanna Unit (MacRoberts et al 2002). They collected primarily in Turkey Creek (2002-03), Big Sandy (2003-04) and Beech Creek (2004). Suzanne Walker, Azimuth Forestry Services, Nacogdoches, TX, was part of their collecting team at Beech Creek. Larry E. Brown, Professor, Houston Community College, began collecting in Big Thicket in the 1970s. Many of his specimens collected prior to 2001 when this project began were retained in the herbarium at the Spring Branch R.A. Vines Science Center, Spring Branch Independent School District, Houston, TX (this herbarium is registered as SBSC). Brown’s early collections were primarily at Menard Creek and Hickory Creek. As part of this project, he collected at Big Sandy (2003-04), Lance Rosier (2004-06) and Turkey Creek (2006). . Dan Johnson, an amateur botanist from Houston collected under his supervision at Hickory Creek and Turkey Creek. A few specimens are listed as collected by Brown and Liggio or by Brown and Harper. Joe Liggio and Shawn Harper accompanied Brown in the field for some collection at Hickory Creek and Lance Rosier. Stanley Jones, consulting botanist, College Station, TX, supplied approximately 1000 specimens to the project from collections made for various consulting firms engaged in seismic prospecting in Jack Gore/Neches Bottom, Beaumont, Lance Rosier, and Big Sandy units. Geyata Ajilvsgi, well-known author and botanist, contributed two specimens from these efforts. Ray Jordan, ophthalmologist, Port Arthur, TX began collecting in the Beaumont Unit in 2006. It is anticipated that he will continue to collect and contribute to the completion of the flora for that unit. William R. Carr, botanist, The Nature Conservancy, made 73 collections, mostly at Big Sandy, as part of a cooperative reconnaissance project with NPS. These specimens were deposited at the University of Texas (TEX-LL). In addition to the collectors identified above, Dixie Environmental Services Company (DESCO) personnel collected twelve specimens in the course of seismic fieldwork in

Units Hickory Creek. Early collections were made in the mid 1970s by Streng and Watson. Additional collections were made by Liu and Harcombe as part of a fire study in the early 1990s. The bulk of the collection was done by the MacRoberts, Johnson and Brown in 2000-01. The flora has been published (MacRoberts et al. 2002).

Turkey Creek. This unit was visited by more collectors than any other unit, beginning with Watson in the 1970s, followed by Harcombe and Liu in the 1990s. The most intensive effort was in 2001-2003 by the MacRoberts, Larry Brown, and Dan Johnson. Additionally, collecting was done by LE Brown as part of a seismic survey in 2006. Intensive study of a sandhill restoration area was done by Caldwell in 2005. Occasional collections were made by Elsik 1994-2005. The flora has been published (Brown et al. 2005).

Big Sandy. Watson collected in this in the 1980s, and Liu and Harcombe collected there in the 1990s. The bulk of the collecting was in 2004-2006 done by Brown and the MacRoberts as part of this project, and by Jones as part of a seismic survey assessment. Pruess and Elsik collected some specimens in 2002. The flora has been published (Brown et al. 2006a).

Lance Rosier. As in the other units, Watson collected in this in the 1980s, and Liu and Harcombe collected there in the 1990s. In addition, the MacRoberts did some collecting in the savannas in the 1990s. The primary effort was made by Brown, Pruess and Elsik in 2004-06. The flora has been published (Brown et al. 2006b)

Beech Creek. Watson collected here in the 1980s and there are a few Harcombe specimens from the 1970s. Most of the collecting was done in 2004-05 by the

- 6 -

MacRoberts and Walker, and subsequently by Pruess and Elsik in 2006. Publication of the flora is anticipated in 2008 (MacRoberts et al. in prep)

Neches Bottom/Jack Gore Baygall. Watson collected here in the 1980s, and there are a few Harcombe specimens from the 1990s. Jones contributed a number of specimens collected as part of a seismic survey in 2001-03. The bulk of the collecting was done by Pruess and Elsik in 2006.

Beaumont Unit Jones collected specimens from this unit as part of a seismic survey in 2001-03. In 2005-07, Jordan made a substantial addition to the specimen records.

Loblolly Unit This unit was visited by Watson in the 1980s, and again sporadically by Brown from the 1980s to 2006. Owing to time constraints, no systematic effort was made to collect in this unit for this project.

Menard Creek. Watson collected here in the 1980s; Brown collected sporadically from the 1980s to 2006. Elsik and Pruess made one collecting trip in 2003. Owing to time constraints, no systematic effort was made to collect in this unit for this project.

The BTNP list At the end of the 5-year effort to find or acquire voucher specimens for all vascular plant species in Big Thicket National Preserve, the database contained information on 8067 specimens, of which 7983 were from the Big Thicket National Preserve; the others had been collected by Watson in the vicinity of the preserve. The specimens from the preserve were mostly collected by Larry Brown, Michael and Barbara MacRoberts, and Stanley Jones. The voucher records represent a total of 1384 valid names (Appendix Table 1). Among these are 120 species represented both by specimens identified only to species and by specimens identified to variety. Since these undoubtedly represent the same taxon in many cases, subtracting the 120 names leaves 1264 verified taxa. This is the most conservative estimate of the number of taxa collected, since in some cases, the specimens not identified to variety may represent varieties not yet recorded from the preserve.

The documented taxa include all but 195 species listed by Geraldine Watson in her 1982 survey of the Big Thicket. Of the taxa not collected (Appendix Table 2 ), some are not valid, or are not known from Texas. Others may have been mis-identifications or misapplications, or may have been erroneously thought to exist within the boundaries of the preserve. Based on information from various sources listed in Appendix Table 2, it is concluded that at least 83 of the taxa can be removed from the list for the reasons listed above. This leaves as many as 110 taxa that may yet be found. Therefore, the flora of BTNP may approach 1400 . The upper bound for the complete flora is set by a regional assessment, which indicates a total of 1700 taxa for the counties containing BTNP (Diggs et al. 2006. ). The 1264 documented taxa represent 536 genera and 146 families. Major families are Asteraceae (176 species), Poaceae (175), Cyperaceae (149) and Fabaceae (91) . These four families account for 43% of all taxa collected. The same four families top the list for east Texas as a whole (Diggs et al. 2006). One difference is that in the east Texas flora the ranks of Cyperaceae and Fabaceae are reversed. The most important genera are Carex (53 spp.), Cyperus (30spp.), Dichanthelium (28 spp.), Rhynchospora (26 spp.), Juncus (21 spp.), and Quercus (17 spp.). It is unusual for a flora like this to have a woody genus like Quercus as one of the most speciose.

Rare and noteworthy species In the course of this study, two new state records were established (Eupatorium semiserratum and Lechea minor; both collected in the Lance Rosier Unit. The following rare species are noted by Brown et al (2005, 2006a, 2006b): • Silene subciliata (Big Sandy) • Phlox nivalis (Big Sandy) • Spiranthes longilabris (Lance Rosier) • Coreopsis intermedia (Turkey Creek-west gulf endemic) • Ophiopogon jaburan (Turkey Creek) • Trillium recurvatum (Turkey Creek)

A total of 40 taxa documented in Big Thicket National Preserve are on the Plant Tracking and Watch List (Texas Conservation Data Center, October 2003). Global and state ranks of these species are given in Appendix Table 1.

DISCUSSION Big Thicket National Preserve contains at least 1264 documented taxa; it may contain as many as 110 additional species. The documented list contains 75-98% of flora of the Big Thicket region, which consists of roughly 1400 (MacRoberts et al 2007) to 1700 (Diggs et al 2006) species. Based on numbers in Diggs et al. (2006), this represents slightly more than ¼ of the flora of the state of Texas, and about half as many species as Louisiana (2423 species) or North and South Carolina (2913 spp).

Numbers of taxa per unit The primary focus of collecting was on the seven major units (Big Sandy, Hickory Creek, Turkey Creek, Beech Creek, Lance Rosier, Jack Gore Baygall-Neches Bottom, and Beaumont). Unit-level floras range in size from approximately 400 to 750 taxa. The existence of the seven independent lists allows an almost unprecedented opportunity for comparisons within a well-defined biogeographic region. Two sorts of comparisons are made here. First, several comparisons provide insight into the degree of completeness of the vouchered lists. These include (1) comparisons of numbers of taxa collected to the numbers of taxa reported by Watson, (2) inspection of distributions of common species across units, and (3) inspection of the lists of species noted by GW that were not vouchered. Second, comparisons among units in numbers of taxa found provide insight into factors influencing species richness in the Big Thicket. The ratio of number of vouchered species to the number of taxa on the original GW list (the “GW index” ) varied among BTNP units from 0.81 to 1.12 (Table 1). Three of the units with high GW index values (Big Sandy, Lance Rosier and Turkey Creek) were the units in which the largest number of specimens was collected (Table 1; Fig. 1 ). Also, unit coverage was more uniform because of the collecting done as part of the systematic surveys related to seismic prospecting. The units with the lowest GW index values (Beech Creek and Jack Gore Baygall-Neches Bottom) were less-intensively collected; further collection may raise the ratios above 0.90. Two anomalies bear mention, Hickory Creek and Beaumont. For the Beaumont Unit, the high GW index is may be related to difficulty of access in the past, which reduced the number on the GW list, coupled with recent intense effort by one collector, Ray Jordan, took the unit on as

- 9 -

his primary collecting focus. For Hickory Creek, MacRoberts et al. (2002) suggested that the low GW index might be due to presence of species on the GW list that were considered probable, but were not actually observed. This is not consistent with the high index at other units, however. Another possible explanation for the discrepancy is loss of species between the early 1980s when Watson compiled her list and the early 2000s when the bulk of the vouchers were collected. Absence of modern specimens for 15 species collected by Watson and 35 species collected by Streng in the 1970s is consistent with this suggestion and also with the dramatic increase in shrub cover and a decline in savanna ground layer vegetation between 1980 and 2007 (Milton 1998). Targeting these species for future collection can provide additional information regarding species loss and its relationship to resources management. Another way of assessing the unit floras is to examine frequency of common species across units . For species found in more than 5 of the 7 major units, only a small fraction (0.03-0.06) is missing from three units (Turkey Creek, Big Sandy, and Lance Rosier), and it is reasonable to infer that these species are likely to occur in these units, especially since at least some are widespread weeds. Other units are missing a larger fraction of the common species, ranging from 0.13 (Jack Gore Baygall-Neches Bottom) to 0.39 (Hickory Creek). For the units missing a larger fraction of the frequent species, it may be noted that these units are smaller and/or contain fewer habitats, and so the missing species are more likely to be truly absent. A final way to assess unit-level taxon lists is to compare voucher lists with the original GW lists. For this analysis, only taxa vouchered in at least one unit were included (i.e., taxa on the GW all-units target list (Appendix Table 3) were excluded). The results (Appendix Table 1) show discrepancies of 100-150 taxa for the major units. While some taxa may well have disappeared or have been placed on the GW unit lists without direct observation, Watson could well have observed many more species than have been documented since she spent an extraordinary amount of time in the field traversing the units, both prior to and during her period of employment as an NPS botanist. Considering the consistency among the different assessments, the number of taxa reported here is undoubtedly an underestimate.

Variation among units in numbers of species. There is wide variation among units in number of species, from 408 at Hickory Creek to 780 at Big Sandy. Numbers of species are commonly correlated with area, but this relationship seems to hold only for four of the 7 units of BTNP (Fig. 2), whereas three of the units (Hickory Creek, Turkey Creek and Big Sandy), fall substantially above the species-area line. Another well-known determinant of species richness is habitat variability. Using the number of vegetation types (sensu Harcombe and Marks 1979) is an indicator of habitat variability, the rank order of units in terms of number of habitats corresponds reasonably well with that for number of species (Table 2). That is, number of habitats is a better predictor of species richness than is area. There are, however, two major exceptions, Hickory Creek, which contains more species than would be expected on the basis of size and habitat number, and Beech Creek, which contains fewer. A probable explanation for these deviations is that Hickory Creek possesses the most species-rich habitat (savanna), whereas the Beech Creek habitats are all closed forest, which generally have relatively low species richness. Presence of savanna probably also explains why Lance Rosier is richer than Jack Gore Baygall-Neches Bottom, even though it contains one less habitat. The evidence presented above suggests that variation among units in number of species is best explained by variation in habitat conditions and by presence of particular species-rich habitats. In contrast, the Neches River floodplain units show more variation among units than might have been expected considering the relative uniformity of habitat conditions in the floodplain. Several species were collected only in the Upper Neches or the Lower Neches corridor units, in spite of their small area. Furthermore, about 40% of the species collected in the Beaumont Unit were not found in Jack Gore-Neches Bottom. Such variation was previously identified for herbaceous vegetation samples by Mohler (1978). The most plausible explanation is increasing frequency and duration of flooding moving south from Upper Neches to Beaumont.

Nativity . Ten percent of the taxa on the BTNP vouchered species list are non-native according to Kartesz & Meacham (1999). The non-native fraction varies from 4% at Hickory Creek to 13% in the Beaumont Unit. In absolute terms, Lance Rosier Unit

- 11 -

contains 71 non-native species, more than any of the other units by about 50%. In this unit, approximately 10% of the taxa are non-native.

Abundance . The distribution of taxon abundances (Fig 3) is unimodal, with uncommon species being slightly more frequent than common ones. It is also strongly left-skewed; there are more rare taxa than common ones and more uncommon than common. This distribution is perhaps not surprising, considering the relatively wide range of habitats in the preserve. The preponderance of uncommon species is also reflected in the frequency distribution of taxon occurrences in units. A total of 436 species occur in only a single unit. This is 30% of all the species documented for the preserve. On average, about 11% of the species in a unit are found only in that unit, but this fraction varies substantially, and two units stand out (Big Sandy and Lance Rosier) . While it is important to avoid over-interpretation, it seems suggestive that these define the western and southwestern edges of the preserve, and perhaps therefore present distinct habitats that do not exist in the other units. In addition, Lance Rosier contains soils deposited by an ancient Trinity River channel, which results in different habitat conditions (Marks & Harcombe 1981). In contrast, the units with fewer species unique to the unit are more northern and eastern, closer to the core area for species of southeastern forests.

CONCLUSION The documented list of species for Big Thicket National Preserve now contains 1265 taxa. Voucher specimens for the collection are deposited at the Tracey Herbarium of Texas A&M University (TAES). A total of 8067 specimen records were assembled as part of this project, representing substantial effort on the part of many botanists over many years. Analysis of historic data suggests that additional fieldwork will increase both the overall total and the individual unit lists.
