Abstract     
An efficient use of resources is vital for effective management, conservation, and monitoring programs for threatened species. The Bog Turtle (Glyptemys muhlenbergii), arguably the rarest turtle in North America, has experienced severe declines due to habitat loss and fragmentation as well as collection of adults for the pet trade. This species is included in Appendix I of the Convention on International Trade of Endangered Species (CITES) and is currently listed as threatened under the U.S. Endangered Species Act and critically endangered under the International Union for the Conservation of Nature (IUCN). In 2010, U.S. Fish and Wildlife Service staff initiated a site prioritization project and categorized all known Bog Turtle wetlands in Maryland based on capture data compiled by the Maryland Department of Natural Resources from 1992-2011. We based wetland prioritization on marked adult populations as well as documentation of recruitment, and extended this method to a drainage basin scale using established Population Analysis Sites (PAS), which often contain multiple wetlands within a connected system. These data were used to designate 30 PAS as priority management areas in order to best allocate resources towards Bog Turtle conservation in Maryland. Specifically, site prioritization results were used to assist with the following objectives: (1) create restoration focus maps and prioritize habitat management and restoration activities; (2) prioritize survey effort for long-term monitoring sites and other wetlands located in priority PAS, including historic sites; and (3) update landowner information and create a list of potential properties for enrollment in conservation easements. The cooperative partnerships formed among several agencies and organizations have aided in the implementation of in-situ management techniques such as woody vegetation control, hydrological restoration, prescribed grazing, and land protection. Many of these techniques are primarily used to address habitat succession and the spread of invasive plants, which may threaten the open-canopy herbaceous wetlands that support Bog Turtles. The continued use of updated population data to guide cooperative management efforts will be critical for the conservation of this imperiled species.
