Research Project: ARS Research Sheep Grazing - USDA ARS U.S. Sheep Experient Station and the USDA Forest Service Caribou-Targhee National Forest Agreement

Location: Range Sheep Production Efficiency Research

2013 Annual Report


1a.Objectives (from AD-416):
Graze defined areas during defined periods. Assess rangeland and forage communites to keep land conditions enhanced and in desirable plant composition.


1b.Approach (from AD-416):
The intention of the research and investigation work by both ARS and the Forest Service shall be for the benefit of the entire sheep and range industry in Idaho and adjacent states, and for the general benefit of the people of the United States in accordance with the interagency agreement FS #12-IA-11041563-007 and the Temporary or Livestock Use Permit issued annually as needed.


3.Progress Report:

The goal of this agreement is to use sheep grazing to annually remove excess forage on various areas of the Caribou-Targhee National Forest. Progress was made by Forest Service (FS) in determining the sheep stocking rates and grazing dates. Agricultural Research Service (ARS) grazed the areas with sheep according the FS’s requirements. ARS scientists assessed post-grazing vegetation utilization. These activities will continue in FY2014. This collaboration supported Objective 2 of the parent project, which is focused on developing science-based grazing management strategies and decision support systems that can be used to guide managers to maintain or improve the ecological function of western rangelands.
