Below are publications and outreach materials, intended to bring awareness & education about invasive plants.



Nonnative Invasive Plants of Pacific Coast Forests: A Field Guide for Identification - The field guide is a prioritized short list of the nonnative invasive plants having the greatest impact on forested lands in the Pacific coastal states of California, Oregon, and Washington. The guide provides enough detail in nontechnical language and photos of different stages of plant development to allow reliable identification of these species in the field. A USDA, Forest Service publication: PNW-GTR-817, May 2011.


Non-Invasive Plants - While most exotic plants are not problematic, a few have become invasive in Washington State. When these plants spread to wild areas, they cause serious problems. For example invasive knotweeds, butterfly bush, and yellow flag iris are changing our stream sides and river banks; spurge laurel and ivy are altering our forests.


Noxious Weeds That Harm Washington State: Field Guide - PDF version of a 50+ page, pocket-size field guide to the most troublesome noxious weeds of Western Washington. Photos, impacts, and methods of control are listed for each weed. This publication also includes a brief introduction that explains how weeds spread, weed laws, and landowner responsibilities.
