    The Forest Inventory and Analysis (FIA) program of the U.S. Forest Service is an ongoing endeavor mandated by Congress to determine the extent, condition, volume, growth, and depletions of timber on the Nation's forest land. FIA has responded to a growing demand for other information about our forests including, but not limited to, soils, vegetation, down woody material, and invasive plants. The intent of this guide is to aid FIA field staff in identifying 44 invasive plant species in the 24-state Northern Research Station region (Maine south to Delaware west to Kansas and north to North Dakota). However, this guide can be used by anyone interested in learning about these invasive plants. It contains distribution maps, short descriptions, space for notes, and numerous pictures of each plant.
