It's Alaska Invasive Species Awareness Week! Today we are highlighting an invasive species in Kodiak: Bohemian Knotweed. Bohemian knotweed is a hybrid between Japanese & giant knotweed, and is one of the most invasive species in Alaska. It can damage infrastructure, contribute to erosion, and also severely degrade wildlife habitat, including for salmon and the invertebrates that they eat. It can easily spread from even small pieces of the stem or roots!
