State Status:

Endangered Species - 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) to be in jeopardy, including but not limited to all species of plants determined to be "endangered species" pursuant to the Endangered Species Act. 

Endangered Species-Possibly Extirpated - 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) to be in jeopardy, including but not limited to all species of plants determined to be "endangered species" pursuant to the Endangered Species Act. This species or subspecies has not been seen in Tennessee for the past twenty years. It is possible that it may no longer occur in Tennessee. 

Possibly Extirpated - A species or subspecies that has not been seen in Tennessee for the past 20 years and may no longer occur in Tennessee. 

Special Concern Species - Any species or subspecies of a plant that is uncommon in Tennessee or has scientific value. This species or subspecies may have unique or highly specific habitat requirements and, therefore, requires careful monitoring of its status. 

Special Concern Species-Commercially Exploited - Any species or subspecies of a plant that is uncommon in Tennessee, has unique or highly specific habitat requirements or scientific value and requires careful monitoring of its status. Since large numbers are being taken from the wild and propagation or cultivation is insufficient to meet market demand, these plants are of long-term conservation concern. However, the Division of Natural Heritage does not recommend they be included in the normal environmental review process. 

Threatened Species - Any species or subspecies of a 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. 

Threatened Species-Commercially Exploited - Any species or subspecies of a 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. Since large numbers are being taken from the wild and propagation or cultivation is insufficient to meet market demand, these plants are of long-term conservation concern. However, the Division of Natural Heritage does not recommend they be included in the normal environmental review process. 

Federal Status:

Candidate Species - These 'Candidate' species are not currently proposed for listing, but development and publication of proposed rules for such candidate species is anticipated. The US Fish and Wildlife Service has on file sufficient information on biological vulnerability and threat(s) to support proposals to list them as endangered or threatened species. The US Fish and Wildlife Service will determine the relative listing priority of these candidate species, and encourages other agencies, groups and individuals to give consideration to these taxa in environmental planning. 

Listed Endangered - The taxon is threatened by extinction throughout all or a significant portion of its range. 

Listed Threatened - The taxon is likely to become an endangered species in the foreseeable future.
