A Manual for the Identification of Invasive Plants in Southern Forests

This manual, “A Manual for the Identification of Invasive Plants in Southern Forests,” was created specifically for use by the US Forest Service Southern Research Station (SRS), Forest Inventory and Analysis (FIA) field survey crews. The SRS FIA unit current 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. Several species within this guide share a common genus, and many “look-a-like” species have been grouped together. Plant names and codes are derived from the USDA Natural Resources Conservation Service’s (NRCS) Plants Databse.
