The diversity of parks and their resources are reflected in their designations as national parks, seashores, historic sites, recreation areas, military parks, memorials, and rivers and trails. Biological, physical, and social science research results, natural resource inventory and monitoring data, scientific literature reviews, bibliographies, and proceedings of technical workshops and conferences related to these park units are disseminated through the NPS/NER Technical Report (NRTR) and Natural Resources Report (NRR) series. The reports are a continuation of series with previous acronyms of NPS/PHSO, NPS/MAR, NPS/BSO-RNR, and NPS/NERBOST. Individual parks may also disseminate information through their own report series. Natural Resources Reports are the designated medium for information on technologies and resource management methods; "how to" resource management papers; proceedings of resource management workshops or conferences; and natural resource program descriptions and resource action plans. Technical Reports are the designated medium for initially disseminating data and results of biological, physical, and social science research that addresses natural resource management issues; natural resource inventories and monitoring activities; scientific literature reviews; bibliographies; and peer-reviewed proceedings of technical workshops, conferences, or symposia. Mention of trade names or commercial products does not constitute endorsement or recommendation for use by the National Park Service. This report was accomplished with assistance from the NPS under Cooperative Agreement 4560A0019, which was superceded by Cooperative Agreement 4506060766, Task Agreement No. 004.

  • "National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
    Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment.

  • Guide to the Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- LILIACEAE
    Guide to the Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- LILIACEAE LILIACEAE de Jussieu 1789 (Lily Family) (also see AGAVACEAE, ALLIACEAE, ALSTROEMERIACEAE, AMARYLLIDACEAE, ASPARAGACEAE, COLCHICACEAE, HEMEROCALLIDACEAE, HOSTACEAE, HYACINTHACEAE, HYPOXIDACEAE, MELANTHIACEAE, NARTHECIACEAE, RUSCACEAE, SMILACACEAE, THEMIDACEAE, TOFIELDIACEAE) As here interpreted narrowly, the Liliaceae constitutes about 11 genera and 550 species, of the Northern Hemisphere. There has been much recent investigation and re-interpretation of evidence regarding the upper-level taxonomy of the Liliales, with strong suggestions that the broad Liliaceae recognized by Cronquist (1981) is artificial and polyphyletic. Cronquist (1993) himself concurs, at least to a degree: "we still await a comprehensive reorganization of the lilies into several families more comparable to other recognized families of angiosperms." Dahlgren & Clifford (1982) and Dahlgren, Clifford, & Yeo (1985) synthesized an early phase in the modern revolution of monocot taxonomy. Since then, additional research, especially molecular (Duvall et al. 1993, Chase et al. 1993, Bogler & Simpson 1995, and many others), has strongly validated the general lines (and many details) of Dahlgren's arrangement. The most recent synthesis (Kubitzki 1998a) is followed as the basis for familial and generic taxonomy of the lilies and their relatives (see summary below). References: Angiosperm Phylogeny Group (1998, 2003); Tamura in Kubitzki (1998a). Our “liliaceous” genera (members of orders placed in the Lilianae) are therefore divided as shown below, largely following Kubitzki (1998a) and some more recent molecular analyses. ALISMATALES TOFIELDIACEAE: Pleea, Tofieldia. LILIALES ALSTROEMERIACEAE: Alstroemeria COLCHICACEAE: Colchicum, Uvularia. LILIACEAE: Clintonia, Erythronium, Lilium, Medeola, Prosartes, Streptopus, Tricyrtis, Tulipa. MELANTHIACEAE: Amianthium, Anticlea, Chamaelirium, Helonias, Melanthium, Schoenocaulon, Stenanthium, Veratrum, Toxicoscordion, Trillium, Xerophyllum, Zigadenus.

  • Concord River Diadromous Fish Restoration FEASIBILITY STUDY
    Concord River Diadromous Fish Restoration FEASIBILITY STUDY Concord River, Massachusetts Talbot Mills Dam Centennial Falls Dam Middlesex Falls DRAFT REPORT FEBRUARY 2016 Prepared for: In partnership with: Prepared by: This page intentionally left blank. Executive Summary Concord River Diadromous Fish Restoration FEASIBILITY STUDY – DRAFT REPORT EXECUTIVE SUMMARY Project Purpose The purpose of this project is to evaluate the feasibility of restoring populations of diadromous fish to the Concord, Sudbury, and Assabet Rivers, collectively known as the SuAsCo Watershed. The primary impediment to fish passage in the Concord River is the Talbot Mills Dam in Billerica, Massachusetts. Prior to reaching the dam, fish must first navigate potential obstacles at the Essex Dam (an active hydro dam with a fish elevator and an eel ladder) on the Merrimack River in Lawrence, Middlesex Falls (a natural bedrock falls and remnants of a breached dam) on the Concord River in Lowell, and Centennial Falls Dam (a hydropower dam with a fish ladder), also on the Concord River in Lowell. Blueback herring Alewife American shad American eel Sea lamprey Species targeted for restoration include both species of river herring (blueback herring and alewife), American shad, American eel, and sea lamprey, all of which are diadromous fish that depend upon passage between marine and freshwater habitats to complete their life cycle. Reasons The impact of diadromous fish species extends for pursuing fish passage restoration in the far beyond the scope of a single restoration Concord River watershed include the importance and historical presence of the project, as they have a broad migratory range target species, the connectivity of and along the Atlantic coast and benefit commercial significant potential habitat within the and recreational fisheries of other species.

It has been accepted for inclusion in The Prairie Naturalist by an authorized administrator of DigitalCommons@University of Nebraska - Lincoln. NOTES OCCURRENCES OF SMALL MAMMAL SPECIES IN A MIXED-GRASS PRAIRIE IN NORTHWESTERN NORTH DAKOTA -- Documentation is limited for many species of vertebrates in the northern Great Plains, particularly northwestern North Dakota (Bailey 1926, Hall 1981). Here we report relative abundances of small « 450 g) species of mammals that were captured incidental to surveys of amphibians and reptiles at Lostwood National Wildlife Refuge (LNWR) in northwestern North Dakota from 1985 to 1987 and 1999 to 2000. Our records include a modest range extension for one species. We also comment on relationships of small mammals on the refuge to vegetation changes associated with fire and grazing disturbances. LNWR encompassed 109 km2 of rolling to hilly moraine in Burke and Mountrail counties, North Dakota (48°37'N; 102°27'W). The area was mostly a native needlegrass-wheatgrass prairie (Stipa-Agropyron; Coupland 1950) inter­ spersed with numerous wetlands 'x = 40 basins/km2) and patches of quaking aspen trees (Populus tremuloides; x = 0.4 ha/patch and 4.8 patches/km2; 1985 data in Murphy 1993:23), with a semi-arid climate.

BACKGROUND and PURPOSE In an effort to encourage the protection of native Maine plants that are naturally reduced or low in number, the State Planning Office has compiled a list of endangered and threatened plants. Of Maine's approximately 1500 native vascular plant species, 155, or about 10%, are included on the Official List of Maine's Plants that are Endangered or Threatened. Of the species on the list, three are also listed at the federal level. The U.S. Fish and Wildlife Service. has des·ignated the Furbish's Lousewort (Pedicularis furbishiae) and Small Whorled Pogonia (lsotria medeoloides) as Endangered species and the Prairie White-fringed Orchid (Platanthera leucophaea) as Threatened. Listing rare plants of a particular state or region is a process rather than an isolated and finite event.

  • A List of Grasses and Grasslike Plants of the Oak Openings, Lucas County
    A LIST OF THE GRASSES AND GRASSLIKE PLANTS OF THE OAK OPENINGS, LUCAS COUNTY, OHIO1 NATHAN WILLIAM EASTERLY Department of Biology, Bowling Green State University, Bowling Green, Ohio 4-3403 ABSTRACT This report is the second of a series of articles to be prepared as a second "Flora of the Oak Openings." The study represents a comprehensive survey of members of the Cyperaceae, Gramineae, Juncaceae, Sparganiaceae, and Xyridaceae in the Oak Openings region. Of the 202 species listed in this study, 34 species reported by Moseley in 1928 were not found during the present investigation. Fifty-seven species found by the present investi- gator were not observed or reported by Moseley. Many of these species or varieties are rare and do not represent a stable part of the flora. Changes in species present or in fre- quency of occurrence of species collected by both Moseley and Easterly may be explained mainly by the alteration of habitats as the Oak Openings region becomes increasingly urbanized or suburbanized. Some species have increased in frequency on the floodplain of Swan Creek, in wet ditches and on the banks of the Norfolk and Western Railroad right-of-way, along newly constructed roadsides, or on dry sandy sites. INTRODUCTION The grass family ranks third among the large plant families of the world. The family ranks number one as far as total numbers of plants that cover fields, mead- ows, or roadsides are concerned. No other family is used as extensively to pro- vide food or shelter or to create a beautiful landscape. The sedge family does not fare as well in terms of commercial importance, but the sedges do make avail- able forage and food for wild fowl and they do contribute plant cover in wet areas where other plants would not be as well adapted.
