![]() By June 2005 the Web site had more than 12,000 unique links. The site began with less than 200 links to external resources. Geological Survey, National Biological Information Infrastructure, and the Council. In June 2000, was launched as a joint collaboration between NAL, the U.S. The Center grew out of NAL's leadership in the development of the Web site for the Council. The Web site serves as a reference gateway to information, organizations, and services about invasive species. The National Invasive Species Information Center (NISIC) was established in 2005 at the National Agricultural Library to meet the information needs of users including the National Invasive Species Council (Council). National Invasive Species Information Center (NISIC) - Gateway to invasive species information covering Federal, State, local, and international sources. The geographical coverage is the United States.įor more information on the NAS program see the NAS Flyer. The data is made available for use by biologists, interagency groups, and the general public. The program provides scientific reports, online/realtime queries, spatial data sets, regional contact lists, and general information. This site has been established as a central repository for accurate and spatially referenced biogeographic accounts of nonindigenous aquatic species. The Nonindigenous Aquatic Species (NAS) information resource for the United States Geological Survey located at the Wetland and Aquatic Research Center. Nonindigenous Aquatic Species (NAS) Information Resource for the United States Geological Survey This paper analyzes surveys of private landowners to identify factors that determine landowner engagement in the conservation of endangered species. Purple loosestrife can change stream velocity, which increases siltation.Ĭooperative Conservation - Determinants of Landowner Engagement in Conserving Endangered Species By: Megan E. Idaho’s noxious weeds include species that make significant modifications to the landscape. Bohemian knotweed is creating monocultures along many Idaho streams, where it lacks the bank stabilizing root system of our native riparian species. Areas within the Czech Republic are seeing reductions in native species because they have lost their pollinators to the nectar of Policeman’s helmet, another Idaho noxious weed. Salt cedar deposits salt on the soil surface from below-ground alkaline water, which leads to the elimination of all salt-sensitive species. Species such as spotted knapweed can accelerate soil erosion. Purple loosestrife can change stream velocity, which increases siltation. ![]() ![]() Idaho’s Noxious Weeds By: Timothy Prather, Sandra Robins, and Don Morishita
