What is an invasive species?
Invasive species are introduced species of animals, insects, plants, fungi, pathogens, and other organisms that if not controlled spread to negatively impact resources. Agriculture, gardens and landscaped areas, and natural resources including fish, game, berries, and other vegetation are often what land managers seek to protect from invasive species impacts. If management does not occur significant changes to affected ecosystems, farms and landscaped areas can cost land owners, managers, and land users significant money to manage or to supplement lost resource use. For more information on invasive species visit the Alaska Division of Agriculture and Alaska Department of Fish and Game web pages. A list of non-native plants and profiles that describe their invasive nature as well as an interactive map of places non-native plants are documented is found at the Alaska Exotic Plant Information Clearinghouse.

Gardening and landscaping
Noxious and invasive weeds, plant diseases, and insect pests are accidentally spread through garden and landscape activities. We can help by planting alternatives to known invasive ornamental plants, inspecting potted plants for unwanted weeds, and ensuring purchased plants are pest and disease free. For more information on landscaping plants to avoid and their alternatives see the Division of Agriculture brochure and the Extension Service publication "Don't Plant a Problem".
