Abstract
This manual was created specifically for use by the U.S. Forest Service Southern Research Station (SRS), Forest Inventory and Analysis (FIA) field survey crews. The SRS FIA unit currently collects data on 33 invasive plants or groups across 13 States. The ability to accurately identify plant species in the field is a crucial component of monitoring a species’ presence and range. Because our field crews are dispersed across several ecological regions, the pages have been designed to allow the user to reorganize and/or remove pages accordingly.
