Plateau forest and WMA on the Tennessee River Gorge's north rim

Prentice Cooper State Forest and Wildlife Management Area is the largest contiguous public land in the Marion County area and one of the most important blocks of plateau forest protected in the southern Cumberland. The forest spans roughly 24,686 acres on Walden Ridge along the north rim of the Tennessee River Gorge, straddling the Marion / Hamilton county boundary. It is jointly managed: the Tennessee Division of Forestry manages the forest, and the Tennessee Wildlife Resources Agency manages it as a Wildlife Management Area. The property supports hunting, hiking, mountain biking, birding, rock climbing, and the middle miles of the Cumberland Trail State Scenic Trail.

History

The forest is named for William Prentice Cooper Jr., a lawyer from Shelbyville who served as Governor of Tennessee from 1939 to 1945. During his administration, Tennessee acquired the plateau lands that now form the core of the state's forest and state-park system; the Walden Ridge acquisition was part of that broader program of 1930s and 1940s public-land purchases that made use of New Deal conservation funding and of post-timber-cutout land available at low prices from lumber and mining companies.

Much of the Walden Ridge portion of what became Prentice Cooper had been cut over for hardwood timber and hemlock between the 1880s and 1920s, with some portions cleared and farmed at modest scale during the same period. By the time the state assembled the forest in the 1940s, the cutover lands were regrowing in second-growth oak, hickory, tulip poplar, and pine, with remnant hemlock only in sheltered gorges and ravines. The state's policy shifted over time from timber management toward a combined forestry-recreation-wildlife mandate, and the forest has been used for cooperative forestry research projects with the University of Tennessee and Auburn.

Terrain and geology

Prentice Cooper sits almost entirely on the Pennsylvanian sandstone caprock of the Cumberland Plateau, at elevations ranging from about 1,600 feet on the plateau surface to 630 feet at the Tennessee River below the gorge rim. The south and west boundaries of the forest follow the edge of the escarpment, where sandstone cliffs drop several hundred feet into the gorge. Interior drainages, Middle Creek, Lost Creek, Hemlock Branch, Ranger Creek, and others, cut narrow side canyons into the plateau surface and support cool, moist cove-hardwood microclimates that differ markedly from the drier oak-hickory uplands on the plateau top. For the underlying geology see the geology page; for the gorge itself see the Tennessee River Gorge page.

Ecology

The forest supports several distinct vegetation communities. The plateau surface is dominated by dry-to-mesic oak-hickory forest with an understory of mountain laurel, azaleas, and blueberries. Sandstone glade communities with specialized plants adapted to thin, acidic soils occur along exposed rim outcrops. Where streams drop off the plateau into side gorges, the forest transitions into cove-hardwood, tulip poplar, American beech, sugar maple, basswood, with remnant eastern hemlock in the deepest shaded ravines. Sandstone seep bogs on the plateau surface host specialized wetland plant communities. The gorge wall below the rim is dominated by chestnut oak and hickory on drier slopes, shifting to more diverse hardwood mixes on sheltered slopes.

Wildlife in Prentice Cooper includes the full complement of southeastern plateau species: white-tailed deer, wild turkey, black bear (re-established in the late 20th century), bobcat, gray fox, eastern cottontail, gray squirrel, and a variety of small mammals. The forest supports one of the regional study populations of the cerulean warbler, a neotropical migratory songbird of conservation concern; Tennessee River Gorge Trust and its partners conduct bird-banding studies along the south rim in coordination with USGS and Alabama A&M University. Other notable breeding birds include worm-eating warbler, yellow-throated warbler, Louisiana waterthrush, wood thrush, and pileated woodpecker. Gray bats from the Nickajack Cave colony forage over the forest during summer evenings. For a broader treatment of the county's wildlife see the fauna page.

Recreation

Prentice Cooper is one of the most heavily used recreation sites in Marion County on a per-acre basis, although the forest's size makes use widely dispersed. Principal recreation uses include:

Hiking. The Cumberland Trail State Scenic Trail crosses the forest from south to north. Within Prentice Cooper, the trail includes the Signal and Edwards Points segment, the upcoming Suck Creek segment, and the Mullins Cove segment. The forest itself has roughly 35 miles of hiking trails in addition to the Cumberland Trail corridor, much of it on former logging grade and gated forest roads.

Hunting. As a TWRA Wildlife Management Area, Prentice Cooper is open to regulated seasons for deer, turkey, small game, and occasional managed bear hunts. Gated interior forest roads are closed during managed-hunt periods (typically November and December) to concentrate hunting pressure and to keep non-hunters off the property during high-risk times. Hunters must hold a TWRA WMA permit in addition to state hunting licenses.

Mountain biking. The forest allows mountain biking on designated gravel and dirt roads, with the Tower Road loop and several connecting routes among the more popular rides. Single-track is limited; the forest is primarily a road-biking and bikepacking destination rather than a technical single-track destination.

Rock climbing. Sandstone cliffs along the plateau rim inside the forest support climbing, though much of the developed climbing in the Marion County portion is at Foster Falls and Denny Cove in South Cumberland State Park, which is a separate parks-system unit. Access to climbing within Prentice Cooper follows general TWRA and Forestry rules; no developed climbing facility or route database is maintained by the managing agencies.

Overlooks. Snooper's Rock, Edwards Point (via the Cumberland Trail), and several smaller rim vantage points within the forest are destinations in their own right. See the overlooks page.

Access and seasons

The forest is approached from the Hamilton County side via the Tower Road gate off Mullins Cove Road, and from the plateau side via gated forest roads. The Marion County portion is smaller and less heavily trailheaded than the Hamilton County portion, though the Cumberland Trail connects the two. Primary parking is at the Tower Road gate (50-plus cars on peak weekends), at several interior trailheads inside the forest, and at gorge-rim pull-offs along Mullins Cove Road. Interior forest roads are closed to vehicles during managed hunt periods but remain open to foot traffic for hikers with blaze orange. Backcountry camping is permitted with a free TWRA permit; three designated camping areas (Hemlock Branch, Davis Pond, and Haley Road) also exist.
