©2008 Institute for Applied Ecology. By Lorena Wisehart, Tom Kaye, and Melissa Kirkland.
An indispensable pocket-sized (4 x 6 in) guide designed to be used by both amateur and professional botanical personnel. Included are clear descriptions of 40 invasives with full color photos. New invaders are presented, as well as established weeds, and the guide includes details about look-alikes to avoid confusion. This is an ideal guide for agency field staff, landowners, and others seeking an easy-to-use, field-friendly resource.
The third printing is new and improved with icons to make finding plants by type (e.g., tree, grass, or flower) flower color easier.
