The National Park Service has again extended the public comment period on a proposed sport hunting and trapping regulatory change. The controversial change proposed for Alaska National Preserve lands would allow state permitted practices like bear baiting, using artificial light to kill bears at den sites, killing coyotes during denning season, and killing of swimming caribou. The techniques were banned by the agency in 2015, and then proposed for re-instatement by the Trump administration. KUAC’s Dan Bross reports.
