WildEarth Guardians, a.k.a. Sinapu, claims that park officials did not adequately consider reintroducing gray wolves into Rocky Mountain National Park to solve the elk population problems.
Park Service biologists considered reintroducing wolves as one alternative to control the elk but nixed the idea because reintroducing a self-sustaining wolf pack was not feasible, because there was no regional wolf reintroduction plan. (The plan to cull elk took six years to finalize, so just imagine.)
But the lawsuit, the bureaucratic excuses, and the culling may miss the larger wolf point. Independent of any human plans, signs suggest the wolves are coming, from the north, and possibly from the south. Maybe it's best to just wait and see what happens.
