Federally owned and managed lands support many of the most valuable ecological resources remaining in the United States. The Department of Defense (DOD) is the third largest federal land management agency in the country, with management responsibilities on over 25 million acres. Military installations, and similar sites managed by NASA and the DOE, often represent some of the largest contiguous tracts of relatively undeveloped lands in otherwise fragmented habitat. As such, they can play an important role in the management of habitat for threatened, endangered, or otherwise sensitive species. While their formal mission is not one of land management, for the past several years, these agencies have regularly supported research on many of these at-risk species with the goal of facilitating the development of guidelines for management of these species in ways that protects their habitats while allowing the agency to meet its mission responsibilities. The objectives of this session will be to bring together researchers from the DOD, other Federal management agencies and collaborating research institutions to discuss cutting edge research on at-risk species, and effects of invasive species, that is currently going taking place at these properties across the United States. Emphasis will be placed on applying these research results to active management programs.
