Caribou are an important source of food for residents of western Alaska, but as environmental conditions and migration patterns change, some local hunters have encountered difficulty accessing the Mulchatna caribou herd (MCH). Existing data describe MCH harvests, herd movements, and caribou abundance through time, but an investigation drawing from traditional ecological knowledge (TEK) has not occurred. This project will integrate TEK with existing knowledge of caribou movements and subsistence harvests. Targeted stakeholders include local tribes, including Bristol Bay Native Association (BBNA), local village councils, the United States Fish and Wildlife Service, Lake Clark National Park and Preserve (LCNP), and...

Climate change is expected to alter the distributions and community composition of stream fishes in the Great Lakes region in the 21st century, in part as a result of altered hydrological systems (stream temperature, streamflow, and habitat). Resource managers need information and tools to understand where fish species and stream habitats are expected to change under future conditions. Fish sample collections and environmental variables from multiple sources across the United States Great Lakes Basin were integrated and used to develop empirical models to predict fish species occurrence under present-day climate conditions. Random Forests models were used to predict the probability of occurrence of 13 lotic fish...

Lake polygons within the Fish Creek Watershed, Alaska were created and classified for a number of variables relevant to size, depth, hydrology, connectivity etc. Products derived from a 5m resolution IfSAR digital surface model by calculating a zero slope. Each feature was expanded by one pixel around the entire perimeter since all waterbodies were truncated by this during the slope calculation. Lakes >=1ha were manually extracted from the dataset and their perimeters further corrected using 2002 CIR orthophotography.
