Saving barrens full of life

tennessee coneflower couchville cedar gladeTennessee coneflower is seen in Couchville cedar glade, a prime example of cedar glade habitat that is a target of preservationists — such as the land acquired recently in Rutherford County by TennGreen Land Conservancy. The Couchville property is managed by the Tennessee Department of Environment and Conservation. It is similar in nature to the TennGreen property in Rutherford County, and is part of a nexus of such glades around the Cumberland Plateau. According to TDEC: “Couchville supports one of the largest known and best quality populations of the Tennessee coneflower (Echinacea tennesseensis), which was delisted as a federally endangered species in September 2011. Couchville also provides one of the finest examples of a glade-barrens complex and protects many rare plant species. The glades are distributed where limestone outcropping and shallow soils limit growth of perennial plants and support annual species like leavenworthia, sporobolus, and sedum. The barrens species, that also includes Tennessee coneflower, occur where soils increase and grasses like little bluestem and side oats grama become dominant. The glades and barrens interface forming a complex.”  Tennessee Department of Environment and Conservation

Cedar glade habitat protected in fast-growing Tennessee county

MURFREESBORO — To close out 2024, TennGreen Land Conservancy and Allen Patton protected 50 acres of globally unique cedar glade habitat in Middle Tennessee’s Rutherford County with a conservation easement.

Called Rockdale Cedar Glades and Woodlands, Patton’s land abuts TennGreen’s Lamar Cedar Glades & Woodlands Conservation Easement, increasing this connected corridor of protected land to an expansive 256 acres. Limestone cedar glades and barrens, which are incredibly diverse but under threat from development and pollution, are found on the protected properties. This additional 50-acre easement is also within the Spring Creek HUC 12 Watershed and the Stones River Upper HUC 12 Watershed, marking it as critical habitat.

(Hellbender Press has previously reported on the special nature and importance of cedar barrens, including one located in Oak Ridge, just on the cusp of the Cumberland Plateau, which is better known for its cedar glades).

LEBANON — TennGreen Land Conservancy joined with Headwaters Reserve LLC to protect and restore a high-risk stream habitat adjacent to Cedars of Lebanon State Park. Located on approximately 47 acres, the property’s streams and wetlands are protected by a conservation easement held by TennGreen in perpetuity.

The waters of this property, called Cedar Forest, are within the Spring Creek watershed, which has been noted to contain more than 28 rare species, including the Tennessee cave salamander (Gyrinophilus palleucus).

Stream restoration, a vital process that breathes new life into natural aquatic environments, is a key objective of this conservation easement, offering numerous benefits to both wildlife and the community.

This permanent protection and intentional restoration will help to remove pollutants from waters in one of the nation’s fastest-growing counties while protecting the resource for generations to come.

TennGreen has previously conserved land in the area to expand Cedars of Lebanon State Park and Natural Area and Cedars of Lebanon State Forest.

60-acre Union Grove acquisition marks first protection of imperiled Tennessee trillium, unknown to scientists until only 2013

MORRISTOWN — In May 2023, the Tennessee Department of Environment and Conservation (TDEC) alerted TennGreen Land Conservancy that a 60-acre swath of land nestled in the forests of Hamblen County known as Union Grove was for sale in East Tennessee. Most interestingly: The property contains some of the only known populations of a native trillium that were described for the first time only 20 years ago.

Union Grove’s owner first alerted University of Tennessee botanists and researchers to the unusual trillium in hopes of safeguarding both the wildflowers and the forests they live within. The botanists realized the trillium was nothing they nor other botanists had encountered and described it as “new to science” in 2013. To date, the Tennessee trillium (Trillium tennesseense) has only been found in the Bays Mountain formation areas in Hamblen and Hawkins counties.

Until this successful collaboration, Trillium tennesseense existed only in private, unprotected areas such as the project landowner’s property. The landowner was moving out of Tennessee, and wished to sell their property to an organization that would value it and seek to protect its incredible habitat. TennGreen Land Conservancy stepped in to quickly acquire the property.

TennGreen then transferred the property to TDEC in June 2024.
