Nonindigenous aquatic pests -- Environmental aspects -- Oregon, Nonindigenous aquatic pests -- Environmental aspects, Aquatic resources -- Oregon -- Management


Aquatic Nuisance Species (ANS) are a serious problem in Oregon. There are currently over 134 nonindigenous aquatic species reported in Oregon. More species are expected to arrive. Current state activities and authorities address some ANS, their prevention, and control. Yet, the activities are not coordinated or comprehensively managing the impacts of ANS. The importance of Oregon’s aquatic resources requires a coherent response to the threat posed by ANS. This management plan is the initial step in establishing a program in Oregon to specifically address ANS issues.


This Plan was prepared with support from the Oregon Watershed Enhancement Board and Portland State University
