To protect natural resources from the threats of invasive species.
Healthy and resilient native ecosystems in the upper Gallatin Watershed.
The alliance began in 2004, when two people witnessed spotted knapweed taking over Gallatin Canyon and decided to take action. Today, our organization is celebrating 16 years of positive impacts on the lands we love.
"Resource managers everywhere recognize that invasive non-native species are the biggest threat to the integrity and function of terrestrial and aquatic environments. The Gallatin watershed is no exception. Over several decades of resources management, I have seen landscapes recover from every type of calamity but I have never seen a landscape recover from the introduction of invasive species.” ~John Councilman, board chair, retired US Forest Service Resource Assistant, Custer-Gallatin National Forest
Our project area encompasses some of the most ecologically and economically important resources in the state, providing vital habitat and water for plants, wildlife, and the people who live and recreate in the area. The Alliance works to address and mitigate the impacts of human activity upon natural resources to ensure that what we love so much about this place is not destroyed by our pursuit to experience it.

Why Should I Care?
The Gallatin Invasive Species Alliance's project area encompasses some of the most ecologically and economically important resources in the state. The Gallatin River is a centerpiece within the Greater Yellowstone Ecosystem and provides vital habitat and water for plants, wildlife, and the people who live and recreate in the area. Those of us who live in this area of Montana choose to do so because of the abundance of recreational opportunities, the amazing and unique wildlife that resides here, and the stunning beauty of the landscape.
The effect of noxious weeds on plant diversity and ecology can cause the loss of wildlife habitat. Infestations of noxious weeds displace native plants and change water flow and availability. Spotted knapweed populations alone reduce available winter forage for elk by 50 to 90 percent. Noxious weeds also increase soil erosion and soil sedimentation, which can have a devastating impact on fishery populations in our local rivers and streams. Runoff is 1.5 times higher and sediment yield was found to be 3 times higher on areas dominated by spotted knapweed than on areas with native grasses.

Leveraging Assistance Through Partnerships
The Alliance spends significant time and effort toward its goal of coordinating efforts and working cooperatively with various federal, state, and local agencies in invasive species education and control within in the project area.
Personnel from partner organizations assist with community events, education and outreach, noxious weed treatments, logistical support, and funding. Their commitment and willingness to participate are major contributors to the successes the Alliance has achieved over the past 14 years.
