Black Bear Population Size and Distribution in Glacier National Park.
Kate Kendall - NRMSC 406/888-7994; Kkendall@usgs.gov

No information exists on the status of the Glacier National Parks (GNP) black bear (Ursus americanus) population. Black bears were sampled in 2004 using noninvasive hair collection methods as part of a 7.8 million-acre study of the regional grizzly bear (U. arctos) population. Data from individual bears will be used in mark-recapture models to estimate black bear population size and to describe density patterns in GNP. Because the cost of all fieldwork and 50% o the genetic analysis has been covered by the grizzly bear project, a comprehensive snapshot of the GNP black bear population will be obtained for 12% o a stand-alone study.
