Grouse managers and conservationists agree on a possible compromise using a model that shows room for 70 pairs of harriers at relatively low cost to grouse shooting. This approach could involve removing excess ...
Research indicates that coyote predation on fawns in the East may not be significant enough to cause deer population decline, especially with reduced doe harvests. In contrast, extremely low doe survival rates combined with high fawn mortality support stabilization of Eastern deer populations.
Researchers argue that life history strategy and social behavior should guide management approaches, as 73% of carnivore species are declining. Highly cohesive social species require strict participation from all group members to ensure population persistence.
