Current Projects

 Missoula County Supported Research and Demonstration Sites:


sheepProject: 
Grazing Research on Missoula City Open Space
Location: Mount Jumbo & The North Hills, Missoula, MT
Objectives: This project has two major objectives. The first is to document what impacts sheep grazing is having on the plant community as a whole. The second is to determine when seed additions are most advantageous for establishing native plants from seed. Each spring, the percent cover of all plant species is measured to track how the plant community has been affected over time as a result of grazing and reseeding.

biosheepProject: 
Integrating Biological Control and Targeted Grazing for the Suppression of Spotted Knapweed
Location: Lake County, Near Polson, MT
Objectives: This project seeks to determine if targeted sheep grazing can be used in conjunction with insect bio-control to more effectively reduce spotted knapweed. It compares insect populations and seed production of spotted knapweed in areas grazed by sheep in July, with areas grazed by sheep in August and areas with biological control only. The area has established insect bio-control populations, therefore grazing treatments also have bio-controls acting in combination with the sheep.  Sheep graze areas until 90% or more of the buds, flowers and seedheads of spotted knapweed are removed.
