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.
KEY WORDS: nonnative, invasive, vegetation monitoring
