Factors Contributing to Effectiveness of Black Bear Transplants

Abstract
Transplants [170] of 112 black bears (U. americanus) in Glacier National Park [Montana, USA] during 1967-1977 were evaluated to identify factors that contributed to transplant success. Distance, number of ridges, elevation gain and physiographic barriers between the trapping and release sites were highly correlated with the success of transplants. Differences in the importance of distance and elevation gain between males and females and between inexperienced and experienced bears were identified. Adult transients may make up a substantial portion of the nuisance bear population.
