Weed District

Weed District


Missoula County Weed District actively promotes and encourages cooperation with local, state, and federal partners beyond the boundaries of Missoula County to support research and education projects that advance the management of invasive species and promote desirable aquatic and terrestrial plant communities in Missoula County, the state of Montana and the Northern Rocky Mountain region.


Our mission is to promote and maintain healthy plant communities by minimizing the ecological and economic impact of invasive species through public education, technology transfer, and monitoring, and by facilitating the involvement of landowners and land/resource management agencies to control the highest-priority species in our most sensitive areas. To carry out our mission, the Missoula County Weed Board emphasizes the areas of coordination, prevention, detection, rapid response, and control.
