The Security Forces Detachment Kittery Survival, Evasion, Resistance, and Escape Facility (SERE School) lies within the Carrabassett Valley of northwestern Maine and contains large tracts of boreal forest and several branches of the Kennebec Headwaters Watershed. Under contract with Naval Facilities Engineering Command Mid-Atlantic Region, GSRC in partnership with Biodiversity Research Institute (http://www.briloon.org/) is conducting a study of the movements of non-native brown (Salmo trutta) within stream reaches within SERE School boundaries as well as a study to determine occupancy and habitat usage of the Federally threatened Canada lynx (Lynx canadensis) on SERE School. The primary objective of the brown trout study is to determine if this species is able to circumnavigate stream barriers (waterfalls and beaver dams) and access areas of critical habitat, inside and outside of installation boundaries, for the Federally endangered Gulf of Maine population of the Atlantic Salmon (Salmo salar) where brown trout may pose a hybridization threat. Data on brown salmon movements and occupancy and habitat usage of Canada lynx at SERE School is fulfilling requirements set forth in the installations Integrated Natural Resources Management Plan and will aid natural resources managers in species conservation and management. This project is 50% complete.
