Moose Movement and Habitat Use in Old Crow Flats, 2007-2009

Summary: As browsers of shrubby vegetation, moose are frequently found beyond the northern forest limit in localized areas of abundant shrub growth, frequently adjacent to rivers and lakes. Moose populations appear to be increasing in the OCF, as well as many other localities within Canada's forest-tundra transition. The increase in moose populations near the northern periphery of their range is frequently attributed to increased shrub growth resulting from climate change, but data linking moose abundance and space use to the distribution of shrubs are scarce, particularly within the forest-tundra transition zone.摘要：作为灌木植被的取食者，驼鹿常出没于北部森林界线以外、局部灌木繁茂的区域，这些区域多紧邻河流与湖泊。加拿大森林-苔原过渡带内的OCF区域及诸多其他点位的驼鹿种群数量似乎均呈增长趋势。驼鹿分布范围北部边缘附近的种群增长，常被归因于气候变化驱动的灌木生长量提升，但将驼鹿丰度与空间利用模式和灌木分布联系起来的相关数据却十分匮乏，尤其是在森林-苔原过渡带内。
