Tennessee exotic pest plant council.


ABSTRACT--The Tennessee Exotic Pest Plant Council has produced this list of invasive exotic plants to serve as a guide for land managers in making responsible decisions about plant use and management decisions. The purposes of this list are to: 1) identify introduced plant species that are invasive or may become invasive and cause damage to native plant communities in Tennessee; 2) rank exotic plants based on their invasive characteristics; 3) foster early detection of these plants; and 4) educate the general public and resource managers in an effort to eliminate the use of invasive exotics in landscaping, restoration, and enhancement projects.


The Tennessee Exotic Pest Plant Council (TN-TPPC) first published the Invasive Exotic Pest Plants in Tennessee list in February 1995. That list was initiated from the "introduced taxa" portion of the Checklist of the Vascular Plants of Tennessee (Wofford and Kral, 1993). Sufficient new information has been collected to warrant this first revision.

Introduced plant species are those not native to a region. They are referred to as exotics. Most introduced species are harmless. However, many species do naturalize and have the potential to spread and negatively impact plant communities. Invasive exotic plants usually exhibit some of the following characteristics: produce many small seeds and begin reproducing within their first few years; can reproduce both by seed and vegetative growth; have no special seed germination requirements; and have long flowering and fruiting periods (Randall and Marinelli, 1996). The ecological impacts of invasive exotics may include: reduction of biodiversity; loss of endangered species...
