      EFFECTS OF BLACK BEARS ON GRIZZLY BEARS * Mattson et al. 13 grizzly bear populations in central Idaho and trans- boundary regions of BC and the USA (North Cascades Grizzly Bear Recovery Team , Mattson and Merrill ). Human-caused mortality continues to confound restoration efforts (Knick and Kasworm , Wielgus. The authors reveal the latest findings about the role grizzly bears play in Yellowstone National Park and the Greater Yellowstone Ecosystem, and contemplate the diverse stakeholder interests and issues in grizzly bear management. Most importantly, this book illustrates our collective commitment to sustain a viable population of wild grizzly.

      We chose grizzly bears, which are also called brown bears in coastal systems, as a surrogate of salmon-influenced ecosystem function because 1) bear population dynamics are strongly linked to salmon abundance ; 2) bears are the terminal predator, consuming salmon in their final life history phase; thus, if there are enough salmon to sustain. Each dot represents the average for a population, all of which are North American. (Estimates of meat consumption come from an extensive data set compiled and generated by Garth Mowat, a researcher from British Columbia). The colored dots with a white center denote averages for the Yellowstone grizzly bear population.

The model was also used to explore how access management might influence grizzly bear populations and timber supply.

Grizzly bears once existed throughout the central and western U.S. (U.S. Fish and Wildlife Service ). Today, grizzly bears within the contiguous states are restricted to 1–2% of their former range and exist in only 5 areas, including the Greater Yellowstone Ecosystem, Glacier National Park and the northern continental.
