Study shows wolf numbers don’t have a big effect on caribou herd

SUMMIT COUNTY — A long-term study of wolves and caribou in the Yukon-Charley Rivers National Preserve, a few hundred miles east of Fairbanks, suggests that a thriving wolf population in the area doesn’t have a significant impact on the caribou herd in the preserve.
Wolf abundance and distribution has been monitored in the 2.5 million acre national preserve since 1993 using radio collars on animals within most of the packs using the area. No wolf study in Alaska, other than one at Denali National Park, has been in place for more years. The latest data from study shows a healthy and rebounding wolf population.
“Wolves depend on healthy populations of large ungulates, like caribou, which in turn respond to vegetation, weather and other habitat patterns across the landscape,” said Tom Liebscher, chief of resources for Yukon-Charley Rivers. ‘These data give us insight into what’s happening across a large range of resources, as well as help other agencies make informed management choices.” Continue reading “Biodiversity: Yukon wolf herd thriving”
