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, making it critical to understand how forest harvest management can effectively support grizzly bear conservation efforts. While many localised studies have investigated the relationships between forest harvest and grizzly bear habitat use, a synthesis of our current understanding of these complex interactions is warranted. We reviewed publications that empirically assessed grizzly bear use of recently harvested forest stands (<40 years since harvest). We found that all studies reported grizzly bear use of forest cut blocks, with several reporting grizzly bear selection of forest cut blocks, however with substantial variation in selection across seasons and local environment (ecoregions). We distill seven underlying factors that influence grizzly bear responses to forest harvest: natural forest openings, cut block design, silvicultural techniques, age since harvest, grizzly bear food availability, human activity, and grizzly bear sex and age. Our synthesis suggests that grizzly bears may frequently use forestry cut blocks when vegetative forage is present, especially if human activity is minimal and natural forest openings are limited. We highlight current knowledge gaps, summarize recommended management actions, and suggest future research directions for balancing forest harvest activities and grizzly bear conservation.

木材生产的积极森林管理，通过使用切割块采伐林分，经常与灰熊（Ursus arctos ）重叠) 北美多用途景观上的栖息地，因此了解森林采伐管理如何有效支持灰熊保护工作至关重要。虽然许多本地研究调查了森林采伐和灰熊栖息地利用之间的关系，但我们目前对这些复杂相互作用的理解有必要进行综合。我们回顾了根据经验评估灰熊对最近采伐的林分（自采伐后 40 年）使用情况的出版物。我们发现所有研究都报告了灰熊对森林砍伐块的使用，有几项研究报告了灰熊对森林砍伐块的选择，但是在不同季节和当地环境（生态区）的选择上存在很大差异。我们提炼出影响灰熊对森林采伐反应的七个潜在因素：天然林开口、切割块设计、造林技术、收获后的年龄、灰熊的食物供应、人类活动以及灰熊的性别和年龄。我们的综合表明，当存在营养草料时，灰熊可能经常使用森林砍伐的块，尤其是在人类活动最少且天然森林开口有限的情况下。我们强调当前的知识差距，总结推荐的管理行动，并建议未来平衡森林采伐活动和灰熊保护的研究方向。尤其是在人类活动极少且天然森林开放有限的情况下。我们强调当前的知识差距，总结推荐的管理行动，并建议未来平衡森林采伐活动和灰熊保护的研究方向。尤其是在人类活动极少且天然森林开放有限的情况下。我们强调当前的知识差距，总结推荐的管理行动，并建议未来平衡森林采伐活动和灰熊保护的研究方向。
