Monitoring of the abundance and activity of Arctic Foxes in the Hudson Bay Lowlands

Arctic foxes are the primary mammalian predator of snow geese in the region. To monitor any changes in their impact on snow goose reproductive success, we developed a rapid, helicopter-based survey technique and apply it annually.北极狐是该区域雪雁的主要哺乳动物捕食者。为监测其对雪雁繁殖成功率的影响变化，我们研发了一种基于直升机的快速调查技术，并每年应用该技术。
