The number of watercraft inspections completed in 2019 across the four Northwest states rose 6 percent from 2018, but the number of contaminated recreational vessels intercepted at the stations that had invasive quagga or zebra mussels attached dropped 2 percent to 93 boats, according to a draft report by the Pacific States Marine Fisheries Commission that was completed last week.

The Western Governors Association has launched the Western Invasive Species Council to enhance coordination between existing state invasive species councils, improve communication and collaboration on regional biosecurity and invasive species control efforts, and to advocate for regional needs at the federal level. Governors appointed 16 members to the new council.
