Invasive species of plants, animals, diseases, and pathogens are estimated to cause more than $137 billion annually in damage to Americans in economic, ecological, and human health costs. Invasive species are best managed by preventing their establishment in the first place or by halting their spread to unaffected areas. But how? The USGS, NASA, and Colorado State University have teamed up to develop a tool to map invasive species and predict where they could be headed.
The cryptic and nocturnal habits of bats render it difficult to assess trends in the status of their populations. To meet this challenge, USGS biologists Mike Bogan and Tom O'Shea hosted an expert workshop to examine the topic of monitoring the status of bat populations. The proceedings are contained in a newly released report, “Monitoring Trends in Bat Populations of the United States and Territories: Problems and Prospects,” Information and Technology Report USGS/BRD/ITR—2003-003.
Over 22 million of the current 34 million acres of the USDA’s Conservation Reserve Program (CRP) contracts will expire in 2007 and 2008. With that rapidly approaching reality in mind, the USDA Farm Service Agency and the U.S. Geological Survey's Fort Collins Science Center sponsored a national conference June 6-8 in Fort Collins, Colorado, on the future of the Conservation Reserve Program.
The National Wildlife Refuge System Improvement Act of 1997 requires that all U.S. Fish and Wildlife Service National Wildlife Refuges develop Comprehensive Conservation Plans (CCPs) to guide refuge management over the next 15 years. One of the FWS’s specific needs was improving the science component of these plans.
The Conservation Reserve Program remains the largest environmental program administered by the U.S. Department of Agriculture, with enrollment exceeding 34 million acres nationwide. Because improvement in program performance is an important goal of CRP administrators, participants' input on how the program is working "on the ground" is an important factor in its evaluation.
USGS Fort Collins Science Center scientists will again visit Orono, Maine, on October 10-11 for a follow-up workshop on SALMOD, a model originally developed for use with declining Pacific salmon. The model will be tested for its applicability in addressing freshwater habitat issues for the endangered Atlantic salmon in Maine.
USGS Fort Collins Science Center scientists will present a preliminary draft of an Atlantic salmon production model to Maine Atlantic Salmon Commission, U.S. Fish and Wildlife Service, and National Oceanic and Atmospheric Administration personnel, university scientists, and others in a meeting August 7-9 in Orono, Maine.
