<DIV><DIV><DIV><I>Invasive Weeds of North America</I> 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.</DIV>
