CHECKLIST

OF WEST TENNESSEE PLANTS

For now, I can offer this checklist of 1,795 species collected in the 21 counties of West Tennessee. This list was generated from vouchers at the University of Tennessee Herbarium ONLY (updated April 27, 2015), and as such is incomplete. Species will be added as I obtain data from other herbaria as well as my own work. Plans for this page include a searchable database of comprehensive information on each species. Bear in mind the county lines do not exactly correlate with the physiographic region of West Tennessee. This website only uses county data to define West Tennessee plants.

The key to the status column is provided at the bottom of the page.

KEY TO STATUS

TENNESSEE NATURAL HERITAGE PROGRAM

 ENDANGERED  Any species or subspecies of plant whose continued existence as a viable component of the state’s flora is determined by the commissioner [of the Department of Environment and Conservation or his/her authorized representatives] to be in jeopardy, including but not limited to all species of plants determined to be “endangered species” pursuant to the Endangered Species Act.

 THREATENED  Any species or subspecies of plant which appears likely, within the foreseeable future, to become endangered throughout all or a significant portion of its range in Tennessee, including but not limited to all species of plants determined to be a “threatened species” pursuant to the Endangered Species Act.

 SPECIAL CONCERN  Any species or subspecies of plant that is uncommon in Tennessee, or has unique or highly specific habitat requirements or scientific value and therefore requires careful monitoring of its status.

State status modifiers:

 POSSIBLY EXTIRPATED  is applied to a species or subspecies that has not been seen in Tennessee for the past 20 years. It is possible that it may no longer occur in Tennessee.

 COMMERCIALLY EXPLOITED  is applied to plants that are being taken from the wild in large numbers and propagation or cultivation is insufficient to meet market demand. These plants are of long-term conservation concern but the division does not recommend they be included in the normal environmental review process.

TENNESSEE EXOTIC PEST PLANT COUNCIL

 ALERT  Possesses invasive characteristics; known to be invasive in similar habitats as those found in Tennessee

 SEVERE THREAT  Possesses invasive characteristics; spread easily in native plant communities and displaces native vegetation

 SIGNIFICANT THREAT  Possesses invasive characteristics; not presently considered to spread as easily into native plant communities as SEVERE THREAT

 LESSER THREAT  Spreads in or near disturbed areas; not presently considered a threat to native plant communities
