Residents & Resident Fisherman


Before leaving a river’s edge, remove any clumps of algae or other vegetation and sediment (leave them at the site). Brush any plant seeds from cuffs, wading shoes and garments that collect seeds.


Be on the lookout and report any unusual sightings. If observed, take a photograph and if possible collect a sample in a baggie and document where the sample was collected - preferably with GPS coordinates. 

To report a sighting call the AK Invasive Species Hotline @ 1-877-INVASIV
