Effects of elk overpopulation

"... excessive spring elk numbers causing heavy utilization of desirable forbs, and riparian sites showing heavy use by big game during spring and early summer.  Elk are implicated in most of the allotments that are not meeting rangeland health standard evaluations in the Hahns Peak-Bear’s Ears District." E2 Elk Management Plan Page #10

Ideal for habitat, the hunter harvest, and the elk is to keep the population of elk close to half of "K" or maximum carrying capacity, or near the middle of the "sigmoid growth curve".

"It means that if we attempt to manage for healthy big game herds, we should attempt to hold the populations at about the middle of the "sigmoid growth curve."  Biologists call this "MSY" or "maximum sustained yield."  At this level, which is exactly half the maximum population size or "K", in this example it would be 5,000 animals, the population should provide the maximum production, survival and available surplus animals for hunter harvest.  Also, at this level, range condition should be good to excellent and range trend should be stableGame damage problems should not be significant and economic return to the local and state economy should be at the maximum.  This population level should produce a "win - win" situation to balance sportsmen and private landowner concerns."  E2 Elk Management Plan Page #18
