ANCHORAGE- The National Park Service is calling for an emergency closure of all sport wolf hunting and trapping in the Yukon-Charley Rivers National Preserve.
John Quinley with the Park Service told KTUU there's been an above-average 40 percent drop in the wolf population over the winter.
The losses include four wolves killed last week by state Fish and Game agents. Two of those wolves had been collared for tracking.
The Park Service says subsistence hunting will continue, but, depending on how public meetings go, sport hunting could be closed for the rest of the season, which runs through May 31.
