New Invaders of the Northwest Guidebook


New Invaders of the Northwest

Rachel Winston and Mark Schwarzlander. 2010. USDA Forest Service Forest Health Technology Enterprise Team.

The purpose of this guide is to help land users recognize new invasive plants early on, before they become large and expensive problems. This hands-on field guide focuses on 62 newly invasive species not yet widely distributed throughout the Northwest. Each species is highlighted with multiple photos and descriptions emphasizing key identification traits, typical habitat, current distribution, and ways to distinguish it from look-alike species. Published by the Forest Health Technology Enterprise Team.
