Uncertain to exactly where they were, but my memory is them using a helicopter a few years back without much success. Even with a radio collar they were unable to visualize some due to the cover. A helicopter works good in some places, not so much in others.
Last year it was the poachers that killed all the calf elk this year its the habitat. If you're waiting for the IDFG to admit they were complicit in the USFWS decision to place wolves in Idaho, pull up a chair and bring plenty of snacks. Plenty of videos of meetings with them on tape claiming they were the experts, and knew what was best. Also plenty of Canadian biologist on record as saying, everything proposed runs contrary to our experience, but it should be interesting to watch.
The habitat's an easy fix some prescribed burns, and logging will open that canopy right up.
