Nonnnative species are altering freshwater and marine ecosystems in the West, and more species are introduced every year.
This identification guide was developed to help watershed councils and other community-based groups increase their understanding of aquatic invasive species, and to initiate monitoring efforts for species of particular concern to their watersheds.
The introduction provides an overview of activities that can spread invasive species, a look at their economic impacts, and suggestions for ways we can work together to prevent and control their spread. The rest of the book covers background information and key identification characteristics of many aquatic invaders that are already established or likely to become established in the West, and tells where to access additional experts and how to report sightings of invasive species.
The 92-page guide is lavishly illustrated with full-color photographs to aid identification, is coil bound to lie flat when opened, and has a laminated cover for water resistance.
