Potential and Recorded Rare Plant Records for the CT

The five tables below are based on dividing the CT into five sections.  The range of these sections is indicated in parentheses. These ranges will change in some cases as more trail is built. Larry Pounds (the author) has seen the bolded species listed below while walking on the CT or nearby in the section where they are shown below. The non-bold species are taken from Tennessee Natural Areas Division online information.  The TN state information gives  location for the species by which quad map they occur on. I have included all such records for quads the CT crosses. Since quads are large, the records may be a few miles from the CT. Some species that are no longer on the TN state list are included below for clarity and are indicated.
