Researchers Discuss Wolf Populations in Animal Conservation
January 08, 2021
Immigrating wolves may not always replenish wolf populations after individuals have been harvested, University of Idaho researchers and their colleagues learned in an eight-year study that included wolf groups in parts of Idaho and Canada. According to a paper published in Animal Conservation by University of Idaho’s David Ausband and Lisette Waits, density of wolves declined after harvest, and immigration into groups was low and did not compensate for harvest mortality in the groups studied by the researchers.
Ausband, the assistant unit leader at the Idaho Cooperative Fish and Wildlife Research Unit in U of I’s College of Natural Resources, and Waits, the college’s distinguished professor of wildlife resources and department head of Fish and Wildlife Sciences, and their colleagues learned that the size of wolf groups and recruitment of offspring declined although the number of occupied territories of wolves in central Idaho did not change after harvest was initiated.
“If the goal of harvest is to reduce density within groups, this means immigration may not negate management efforts,” according to the findings.
