The Alberta MNR did a covert wolf plant here in Alberta on a large military base Suffield .Of course they didn't want to tell the area ranchers , the wolves tore their cattle apart as opposed to chasing the abundant elk that were harder to catch.Angry locals cured the problem with lead and only one black lobo male is still at large.My son seen him a couple years back on an elk cull 1/4 mile out and running hard.Harold
