Rare and Endangered Species



Data Coverage

TDEC Natural HeritageThe Natural Heritage Program currently tracks over 1100 rare and endangered plant and animal species as well as hundreds of conservation sites across the state. This information is collected through ongoing research and field investigations by the Division and other scientists from across the State, as well as from scientific literature, museum collections, and other sources and is continually analyzed and updated. Natural Heritage data is not only important in identifying areas of ecological significance for conservation and restoration activities, but is also a valuable tool in the environmental review process.

Data Requests and Environmental Review

The Division of Natural Areas maintains the state's most comprehensive and up to date repository of data regarding the status and distribution of state and federal concern plant and animal species, ecologically important sites, and conservation managed lands. These data can be used in the planning process or as a general screening tool for identifying potential impacts to natural heritage resources, however they cannot be substituted for on-site biological surveys. At this time, the DNA offers the following information services:

  • Generalized Data………… charge
    The DNA offers generalized data for no charge through its web site. Such generalized data includes lists of rare species for the state, by county, by watershed, and by USGS 1:24000 quadrangle.

  • Site Specific Coverage/Project Review ……….$100/project; add $30 for each additional USGS Quadrangle Covered
    The DNA offers site-specific data of known state and federal concern plant and animal species, ecologically significant sites, and certain conservation managed lands for $100 per project. DNA staff will prepare and send to the requesting entity a map of rare species documented within a one-mile radius of the project area, as well as a list of species documented from the surrounding area. Larger projects and linear projects that cover an area greater than a 4-mile radius shall be charged $30 for each additional USGS 1:24,000 quadrangle included in the project area. Please complete the Project Review Form and submit, along with a site map, to the Natural Heritage Data Manager. Data requests are usually filled within 10 working days and e-mailed or mailed to the receiving entity after payment is received.

  • Office Visit…………………no charge
    The DNA hopes to facilitate the environmental review process as much as possible and encourages those wishing to conduct a review to fully utilize the information supplied on this web site. If you feel additional information is required and you would prefer to visit our office and perform the review yourself utilizing our GIS workstation, please contact the data manager.
