Invasive Weeds of North America is an identification guide to invasive and noxious plants that can cause economic and ecological damage to crops, range, forests, and wildlands throughout North America. Most of these problematic plants are non-natives that now grow in locations beyond their known historic range. A non-native designation can refer to a plant from other continents, regions, or ecosystems. Once in a new area, these plants can establish and spread, free from their natural competitors. Laminated for durability, this handy guide is a great source of portable information and ideal for field use by novices and experts alike. Waterford Press. 12 panels: 9.2 x 21 cm folded.
