Walker Branch is a 225-acre natural area located just 3 miles south of Savannah in Hardin County. The property was purchased with wetland acquisition funds by TWRA who cooperatively manages the site with the Natural Areas Program. It is located in the West Tennessee Uplands, a subunit of the Coastal Plain Physiographic Province. The preserve “straddles” the immediate floodplain of the Tennessee River with its steep hills rising abruptly 225 feet and forming the adjacent uplands. Seeps occur along the lower and mid slopes and drain into the many small spring feed sand and gravel bottomed creeks at the base of the hills. These seep-fed creeks flow in and out of the marshes and swamp forests.
Undisturbed examples of a bald cypress forest emerge at the base of these hills grading into mature tupelo gum (Nyssa aquatic) forest in the floodplain. A mesic forest comprised of northern red oak, American beech, tulip poplar, and white oak is found on lower to mid slopes. Southern red oak and short leaf pine are dominant species that occur on drier slopes and ridges. The many forest types at Walker Branch provide a colorfully diverse shrub layer ranging from indigo bush, deciduous holly, American beautyberry, big-leafed snowbell, hearts-a-bustin, wild azalea, and blueberries.
The upland seeps provide significant breeding habitat for dragonflies and damselflies. An astonishing 39 species of these taxa have been identified at Walker Branch. Examples include Laura’s clubtail, arrowhead spiketail, harlequin darner, great blue skimmer, and the treetop emerald. State rare and endangered plant species that are protected at this preserve include the lake-bank sedge (Carex lacustris) and lamance iris (Iris brevicaulis). There is a vast diversity of sedges, rushes, and ferns in this wet, lush natural area.
