Effects of continued feeding vs. no feeding on elk population size & chronic wasting disease prevalence
By Northern Rocky Mountain Science Center
December 2024 (approx.)
Detailed Description
The figures show the modeled effects of continued winter supplemental feeding versus no feeding on elk population size (panel A) and chronic wasting disease prevalence (panel B) at the National Elk Refuge. Fine lines represent the outcomes over a 20-year time window of the 100 times the models were run and allows people to visualize the range or variation of potential outcomes. Bold lines are the average of those 100 simulations.

Predicting the effects of supplemental feeding and chronic wasting disease in Greater Yellowstone Ecosystem elk
To support management decisions concerning 500 bison and 8,000 elk in Jackson, Wyoming, USGS scientists assessed how alternative U.S. Fish and Wildlife Service plans for providing supplemental food would influence: 1) chronic wasting disease prevalence, 2) elk and bison numbers, 3) wildlife movement and human-wildlife conflict 4) multiple use opportunities for the public, like hunting, and 5)...
