Wyoming Project

Wildlife-Livestock Disease Transmission in a Changing Climate

September 2014 - September 2018


Participating Agencies

  • United States Department of Agriculture
  • U.S. Geological Survey
When cattle and elk comingle during the brucellosis abortion season (from March through May), there is a risk of disease transmission from elk to cattle.

The goal of this project is to develop a framework for understanding the ecology of elk-cattle commingling, particularly with regards to how annual forage conditions and weather patterns influence elk movement during the critical spring/summer brucellosis transmission period. Elk habitat use and cattle grazing regimes are largely determined by the changing distribution of high-quality forage throughout the year.
