Within the 2.5 million acres of the Yukon-Charley Rivers National Preserve in central Alaska, wolves and other majestic animals are protected. But animals like wolves do not respect lines drawn on a map. And a recent study suggests that efforts to limit populations of these predators outside those borders is having negative effects on wolves living within the preserve.
The study, published in June in Wildlife Monographs, suggests that when the Alaskan authorities were limiting wolf populations outside the Yukon-Charley preserve, survival rates of wolves within the preserve were lower than usual. The findings highlight the notion that managing wildlife within human-imposed boundaries requires communication and cooperation with the authorities beyond a preserve’s boundaries, and could have implications for wildlife management programs elsewhere.
