View brief.

The Western Governors’ Association (WGA) has addressed this need by surveying invasive species coordinators in WGA member states and territories Top 50 Invasive Species in the West to develop the “Top 50 Invasive Species in the West.” The compilation of terrestrial and aquatic invasive species includes highly-publicized examples such as cheatgrass, Quagga Mussels, tamarisk and the Emerald Ash Borer. The list also encompasses less well known, but still impactful, examples such as leafy spurge, Red shiner, Russian knapweed, and Golden algae.
