Population fragmentation compromises population viability, reduces a species ability to respond toclimate change, and ultimately may reduce biodiversi ty. We studied the current state and potential causes offragmentation in grizzly bears over approximat ely 1,000,000 km of western Canada, the northern United States(US), and southeast Alaska. We compiled much of our data from projects undertaken with a variety of researchobjectives including population estimation and trend, landscape fragmentation, habitat selection, vital rates, andresponse to human development. Our prim ary analytical techniques stemmed from genetic analysis of 3,134 bears,supplemented with radiotelemetry data from 792 bears. We used 15 locus microsatellite...
Fragmentation is a growing threat to wildlife worldwide and managers need solutions to reverseits impacts on species’ populations. Populations of grizzly bears (Ursus arctos), often considered an umbrellaand focal species for largemammal conservation, are fragmented by human settlement and major highways inthe trans-border region of southern British Columbia, northern Montana, Idaho, and northeasternWashington. To improve prospects for bear movement among 5 small fragmented grizzly bearsubpopulations, we asked 2 inter-related questions: Are there preferred linkage habitats for grizzly bearsacross settled valleys with major highways in the fragmented trans-border region, and if so, could we predictthem using a combination...

Gravel-bed river floodplains in mountain landscapes disproportionately concentrate diverse habitats, nutrient cycling, productivity of biota, and species interactions. Although stream ecologists know that river channel and floodplain habitats used by aquatic organisms are maintained by hydrologic regimes that mobilize gravel-bed sediments, terrestrial ecologists have largely been unaware of the importance of floodplain structures and processes to the life requirements of a wide variety of species. We provide insight into gravel-bed rivers as the ecological nexus of glaciated mountain landscapes. We show why gravel-bed river floodplains are the primary arena where interactions take place among aquatic, avian, and...
This project is an initiative to secure landscape-scale movement opportunities for multiple wildlife species in the Rocky Mountains of Montana and Idaho and adjacent transboundary areas of British Columbia and Alberta. Identify specific wildlife linkage locations across highways 1, 2, 200, 95 and I-90 in Northwest Montana and North Idaho. Recommend and implement with partners conservation delivery in these areas on public and private lands, and across highways to make these movement areas more permeable to wildlife.
