Invasive Plants and Agricultural Pest Management
Welcome to Alaska's Invasive Plant Program. Our program coordinates prevention, outreach and management strategies for invasive plant issues through collaboration with land managers, agencies, organizations and policy makers across Alaska. These efforts are guided by the implementation of our Strategic Plan and relevant noxious weed regulations and policies. Our goal is to help keep Alaska's pristine landscapes and natural resources free from impacts of noxious and invasive plants.
