Species that are considered high risk have a well-documented history of invasiveness in at least one location globally, and a high or medium climate match to the contiguous United States.
C. lavaretus is a salmonid fish species native to Europe. Introductions to counties outside its native range have resulted in negative impacts for native species. The species is one of the most widely introduced fish species in northern Europe and has partially or completely displaced many native Arctic charr (Salvelinus alpinus) populations. Foraging by introduced C. lavaretus can change the structure structure
Something temporarily or permanently constructed, built, or placed; and constructed of natural or manufactured parts including, but not limited to, a building, shed, cabin, porch, bridge, walkway, stair steps, sign, landing, platform, dock, rack, fence, telecommunication device, antennae, fish cleaning table, satellite dish/mount, or well head.
