Parks, Natural Areas Preservation - As enacted, revises the descriptions of existing state natural areas and designates new natural areas. - Amends TCA Title 11, Chapter 14, Part 1.

HB 126 revises Tennessee's state natural areas by updating acreage descriptions for existing protected lands and designating four new natural areas. It increases protected acreage for sites like Barnett's Woods (from 40 to 156 acres) and adds new areas including Clifty Creek Gorge (89 acres protecting the federally threatened Virginia spirea), Rocky Hill (1 acre safeguarding the endangered running glade clover), Union Grove (59 acres preserving the Tennessee trillium), and Versailles Knob (40 acres protecting Braun's Rockcress). The bill directly affects conservation efforts by expanding legal protections for specific endangered species and habitats across Morgan, Rutherford, and Hamblen counties. Enacted on April 11, 2025, it formalizes these land designations without introducing new funding or regulatory requirements.
