This report is submitted to the 2011 Legislature to meet the biennial reporting directive of Chapter 77.60.130 RCW. This is the Aquatic Nuisance Species Committee.s (ANSC) fifth biennial report to the Legislature since its establishment under SSB 6294 (2000 c 149).
The ANSC was formed primarily to foster state, federal, tribal, and private cooperation on Aquatic Nuisance Species issues (hereafter termed Aquatic Invasive Species or AIS), and implement the Washington State AIS Management Plan. Members cooperatively identify and implement tools and management practices that minimize the unauthorized or accidental introduction and spread of nonnative aquatic species such as Spartina, milfoil, elodea, invasive tunicates, crayfish, nutria, and zebra and quagga mussels. This report summarizes the ANSC.s accomplishments and provides recommendations to the Legislature for accomplishing the purposes of statute directives.
Primary accomplishments for the 2008 and 2009 are summarized below for the ANSC as a whole and by state and federal agency, tribal government, and NGO participants.
Aquatic Nuisance Species Committee
The Aquatic Nuisance Species Committee (ANSC) works on multiple levels to foster cooperation including facilitation, providing substantive reviews and recommendations, creating species or issue-specific subgroups, and developing consensus products. Specific accomplishments include:

- Include invasive species in their Action Agenda (Priority action A.5);
- Design and implement a "Clean Your Hull" outreach campaign;

The Washington Department of Fish and Wildlife (WDFW) manages priority AIS at various levels depending upon legislative directive and available resources. There are three primary aquatic invasive species management programs including for zebra and quagga mussels, invasive tunicates, and ballast water.
