| Summary: | Active forest management for timber production, through the harvesting of forest stands using cut blocks, frequently overlaps grizzly bear (Ursus arctos) habitat on multi-use landscapes in North America. Thus, it is critical to understand how forest harvest management can effectively support grizzly bear conservation efforts. While many localized studies have investigated relationships between forest harvest and grizzly bear habitat use, a synthesis of our current understanding of these complex interactions is warranted. This thesis reviewed publications that empirically assessed grizzly bear use of recently harvested forest stands (<40 years since harvest) and found all studies reported grizzly bear use of forest cut blocks. Several studies reported grizzly bear selection of forest cut blocks, however with substantial variation in selection across seasons and local environment (ecoregions). Seven underlying factors were identified that influence grizzly bear responses to forest harvest: natural forest ... |
