  • "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.

    2017 REGIONAL WATER PLAN ALTAMAHA REGION BACKGROUND The Altamaha Regional Water Plan was initially completed in 2011 and subsequently updated in 2017. The plan outlines near-term and long-term Counties: Appling, Bleckley, strategies to meet water needs through 2050. The Altamaha River, formed Candler, Dodge, Emanuel, by the confluence of the Ocmulgee and Oconee Rivers, is the major surface Evans, Jeff Davis, Johnson, water feature in the region. The Altamaha Region encompasses several Montgomery, Tattnall, Telfair, Toombs, Treutlen, Wayne, major population centers including Vidalia, Jesup, Swainsboro, Eastman, Wheeler, Wilcox and Glennville. OVERVIEW OF ALTAMAHA REGION The Altamaha Region includes 16 counties in the south central portion of Georgia. Over the next 35 years, the population of the region is projected to increase from approximately 256,000 to 285,000 residents. Key economic drivers in the region include agriculture, forestry, professional and business services, education, healthcare, manufacturing, public administration, fishing and hunting, and construction. KEY WATER RESOURCE ISSUES Groundwater (the majority from the Floridan aquifer) is forecasted to meet about 70% ADDRESSED BY THE COUNCIL of the water supply needs, with agricultural and industrial uses being the dominant 1. Current and future groundwater demand sectors. Surface water is utilized to meet about 30% of the forecasted water supplies for municipal/domestic, supply needs, with agriculture and energy as the dominant demand sectors.

Gillette Museum of Arthropod Diversity, Department of Bioagricultural Sciences and Pest Management Colorado State University, Fort Collins, CO 80523 Abstract A list of 1531 species ofLepidoptera is presented, collected over 15 years (1988 to 2002), in eleven southern West Virginia counties. A variety of collecting methods was used, including netting, light attracting, light trapping and pheromone trapping. The specimens were identified by the currently available pictorial sources and determination keys. Many were also sent to specialists for confirmation or identification. The majority of the data was from Kanawha County, reflecting the area of more intensive sampling effort by the senior author. This imbalance of data between Kanawha County and other counties should even out with further sampling of the area. Key Words: Appalachian Mountains,

  • Grass Varieties for North Dakota

Duckwitz Plant Materials Center Manager, USDA-NRCS, Bismarck John R. Hendrickson Research Rangeland Management Specialist, USDA-ARS, Mandan North Dakota State University Fargo, North Dakota June 2011 election of the appropriate species and variety is an important step in making a grass seeding successful. Grass species and varieties differ in growth habit, productivity, forage quality, drought resistance, tolerance Sto grazing, winter hardiness, seedling vigor, salinity tolerance and many other characteristics. Therefore, selection should be based on the climate, soils, intended use and the planned management. Planting a well-adapted selection also can provide long-term benefi ts and affect future productivity of the stand. This publication is designed to assist North Dakota producers and land managers in selecting perennial grass species and varieties for rangeland and pasture seeding and conservation planting. Each species is described following a list of recommended varieties Contents (releases). Variety origin and the date released are Introduction. 2 included for additional reference.

  • Insect Survey of Four Longleaf Pine Preserves
    A SURVEY OF THE MOTHS, BUTTERFLIES, AND GRASSHOPPERS OF FOUR NATURE CONSERVANCY PRESERVES IN SOUTHEASTERN NORTH CAROLINA Stephen P. Hall and Dale F. Schweitzer November 15, 1993 ABSTRACT Moths, butterflies, and grasshoppers were surveyed within four longleaf pine preserves owned by the North Carolina Nature Conservancy during the growing season of 1991 and 1992. Over 7,000 specimens (either collected or seen in the field) were identified, representing 512 different species and 28 families. Forty-one of these we consider to be distinctive of the two fire- maintained communities principally under investigation, the longleaf pine savannas and flatwoods. An additional 14 species we consider distinctive of the pocosins that occur in close association with the savannas and flatwoods. Twenty nine species appear to be rare enough to be included on the list of elements monitored by the North Carolina Natural Heritage Program (eight others in this category have been reported from one of these sites, the Green Swamp, but were not observed in this study). Two of the moths collected, Spartiniphaga carterae and Agrotis buchholzi, are currently candidates for federal listing as Threatened or Endangered species. Another species, Hemipachnobia s. subporphyrea, appears to be endemic to North Carolina and should also be considered for federal candidate status. With few exceptions, even the species that seem to be most closely associated with savannas and flatwoods show few direct defenses against fire, the primary force responsible for maintaining these communities. Instead, the majority of these insects probably survive within this region due to their ability to rapidly re-colonize recently burned areas from small, well-dispersed refugia.

  • Endangered Species
    FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.
