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.

Alaska Weeds Identification Application

We are pleased to announce that "Alaska Weeds ID", a mobile application for identification and reporting invasive weeds in Alaska is available for free. The app works for both IOS and Android devices. It includes an interactive key, and form to report sightings of potential invasive weeds or get identification help. The app development was done in partnership with the University of Georgia and others, with support of the Western Alaska Landscape Conservation Cooperative and funding from the U.S. Geological Survey and U.S. Fish and Wildlife Service.

Aquatic Invasive Species Information

Elodea species are an emerging issue for aquatic invasive species management in Alaska.  The Alaska Division of Agriculture is leading efforts to manage Elodea.  Get more information and find out how to help here.

Annual Invasive Species Workshop

The 2015 workshop was held October 27-29 in the City of Juneau at the Elizabeth Peratrovich Hall.  

The City and Borough of Juneau is a hub community for Southeast Alaska where a variety of invasive species issues are addressed. Southeast Alaska, has an active invasive species management group working on issues ranging from eradication of garlic mustard, Didemnun vexillum, and spotted knapweed to ongoing management of knotweeds and reed canarygrass. This year's workshop hosted a variety of topics highlighting invasive species management and science in Southeast Alaska as well as emerging issues statewide. 

For more information about the conference visit our workshop page.

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".

Report invasive species locations and get pest identification help

Extension staff and faculty around the state work with partners to identify thebugs, weeds and plant diseases that are affecting your garden, farms or wild plants.  We encourage sightings of priority invasive species and curious observations.  To access this free service simply fill out the online form, including pictures of the pest, here.
