Little Mountain

Little Mountain encompasses 8,172 acres of montane terrain in the Monongahela National Forest, with elevations ranging from 2,625 feet in Slavin Hollow to 3,415 feet at the summit of Little Mountain. The area drains into the Brush Run-Greenbrier River headwaters system, with water moving through named tributaries including Allegheny Run, Cup Run, Deever Run, Laurel Run, Spillman Run, Trout Run, and Wanless Run. These streams originate in the higher elevations and flow downslope through narrow hollows, creating the hydrological backbone of the landscape and supporting distinct aquatic communities at different elevations.

The forest composition shifts with elevation and moisture availability. At higher elevations and on exposed ridges like Sandy Ridge, Central Appalachian Xeric Chestnut Oak-Virginia Pine Woodland dominates, with chestnut oak (Quercus montana) and Virginia pine as the primary canopy species. In the moister coves and lower elevations, Mixed Mesophytic Forest (Cove Hardwoods) takes hold, where eastern hemlock (Tsuga canadensis), sugar maple (Acer saccharum), and striped maple (Acer pensylvanicum) create a dense, shaded environment. Great rhododendron (Rhododendron maximum) and mountain laurel (Kalmia latifolia) form extensive understory thickets throughout the area, particularly in the transition zones between ridges and hollows. The forest floor supports specialized herbaceous species including Fraser's sedge (Carex fraseriana), white alumroot (Heuchera alba), and Epling's hedge-nettle (Stachys eplingii), a critically imperiled species found only in scattered locations across Appalachia.

The streams support populations of the federally endangered candy darter (Etheostoma osburni), a small fish restricted to clear, cool headwater streams with critical habitat designated within this area. Brook trout (Salvelinus fontinalis) inhabit the same cold-water reaches, where they compete for invertebrate prey in the stream substrate. The federally endangered Indiana bat (Myotis sodalis) and northern long-eared bat (Myotis septentrionalis) forage over the forest canopy and roost in tree cavities and under loose bark. The federally endangered rusty patched bumble bee (Bombus affinis) visits flowering plants in forest gaps and along stream margins. In the cove forests, the Cheat Mountain salamander (Plethodon nettingi) occupies the leaf litter and rocky substrates of seepage areas, while the hellbender (Cryptobranchus alleganiensis), a near threatened aquatic salamander, inhabits the larger streams. American black bears move through all forest types, feeding on mast in oak-hickory areas and on herbaceous vegetation in coves.

Walking through Little Mountain, a visitor experiences distinct ecological transitions. Following Trout Run upstream from lower elevations, the forest begins in mixed hardwoods with an open understory, then darkens as eastern hemlock becomes more abundant and great rhododendron thickens the mid-story. The stream itself narrows and steepens, its water audibly colder and clearer. Climbing from the hollow onto Sandy Ridge, the forest opens suddenly—the hemlock and rhododendron give way to chestnut oak woodland with sparse understory and a carpet of leaf litter. The air feels drier, and views extend across the ridge system. Descending into Slavin Hollow on the opposite side reverses the sequence: the forest deepens again, rhododendron closes in, and the sound of running water returns. Throughout the area, the presence of threatened plants like Virginia spiraea in seepage areas and small whorled pogonia (Isotria medeoloides) in specific forest microsites marks this landscape as ecologically distinct within the Central Appalachian region.

Indigenous peoples used the high-elevation areas of the Monongahela region, including Little Mountain, primarily as seasonal hunting grounds for deer, elk, bear, and turkey. The Monongahela Culture, a Late Woodland archaeological tradition dating from approximately AD 1050 to 1635, inhabited the northern West Virginia watershed and built circular, stockaded villages in the river valleys below, where they practiced maize agriculture. Archaeological evidence from across the Monongahela National Forest documents Indigenous presence through lithic scatters—including chert flakes from stone tool sharpening—that indicate temporary hunting camps and tool maintenance. The Lenape people, whose language provides the forest's name (meaning "place of many landslides" or "high banks falling down"), historically used and passed through this region. By the 18th century, the Shawnee claimed the lands west of the Alleghenies as hunting grounds. The Haudenosaunee (Iroquois) Confederacy, during the 17th-century "Beaver Wars," expanded into the Ohio Valley to control fur-trading hunting grounds, often displacing resident groups. The Cherokee and Mingo, an independent Iroquoian-speaking group, also hunted in the region during the 18th century. Ancient Indigenous trails crisscrossed the mountains, following drainage divides and ridges as routes for trade and warfare, including the documented Seneca Trail that linked Algonquin, Tuscarora, and Seneca tribes along the Potomac River.

By the mid-18th century, the "Beaver Wars" and European encroachment had displaced many resident Indigenous groups. The Proclamation of 1763 attempted to establish the Allegheny Mountains as a boundary between settler and Indigenous lands, but westward migration largely ignored this boundary.

During the late 19th and early 20th centuries, the region underwent intensive industrial logging. Nearly all virgin spruce and hardwood forests in the West Virginia highlands were harvested. Logging operations accessed the timber through a dense network of narrow-gauge railroad grades, built with Shay geared locomotives to reach steep timber stands in virtually every hollow and mountain, including those now in roadless areas. Timber hubs such as Durbin and Marlinton served as major centers for the Durbin and Greenbrier Valley Railroad and lumber companies including the Pocahontas Lumber Company. Logging operations left behind extensive "slash"—piles of branches and debris—which created tinderbox conditions that led to destructive wildfires. The removal of forest cover and subsequent fires caused severe soil erosion and devastating downstream flooding, most notably the 1907 Pittsburgh flood. This ecological damage prompted federal action.

The Monongahela National Forest was established through the Weeks Act of 1911, which authorized the federal government to purchase private "cut-over" and "burnt-over" lands to protect the headwaters of navigable streams. The first tract acquired under this authority was the Arnold Tract of 7,200 acres in Tucker County, purchased on November 26, 1915. President Woodrow Wilson signed Proclamation 1561 on April 28, 1920, formally designating the acquired lands as the Monongahela National Forest. At its founding, the forest comprised approximately 54,000 acres of federally owned land. During the 1930s Great Depression, the forest underwent its most significant expansion, with acreage increasing from approximately 261,968 acres in 1932 to over 806,000 acres by 1942. The Civilian Conservation Corps operated extensively in the forest during this period, planting millions of trees on denuded slopes, constructing fire breaks, trails, and fire towers, some of which remain today. On April 28, 1936, President Franklin D. Roosevelt signed Proclamation 2166, which transferred lands in Hardy County, West Virginia, and western Virginia to the George Washington National Forest while expanding the Monongahela's boundary southwest near Richwood. The Spruce Knob-Seneca Rocks National Recreation Area, encompassing approximately 100,000 acres, was established within the forest boundaries by Public Law 89-207 on September 28, 1965. The Eastern Wilderness Act of 1975 designated the Otter Creek and Dolly Sods Wilderness areas; subsequent designations in 1983 established the Cranberry, Laurel Fork North, and Laurel Fork South Wilderness areas, with Cranberry further expanded in 2009. Little Mountain became an Inventoried Roadless Area protected under the 2001 Roadless Area Conservation Rule.

Vital Resources Protected

Headwater Protection for Endangered Aquatic Species

Little Mountain's roadless condition preserves the headwaters of the Brush Run–Greenbrier River system and tributary networks including Allegheny Run, Trout Run, and Laurel Run—streams that provide critical spawning and rearing habitat for the federally endangered candy darter (Etheostoma osburni), which has designated critical habitat within this drainage. The unbroken forest canopy and intact riparian buffers in this roadless area maintain the cool, clear water conditions and stable substrates that candy darters require for reproduction. Loss of this headwater protection would degrade water quality across the entire downstream Greenbrier system, eliminating one of the few remaining populations of this species.

Interior Forest Habitat for Bat Populations and Forest-Interior Birds

The 8,172-acre unfragmented forest interior provides essential habitat for three federally endangered bat species—Indiana bat (Myotis sodalis), Northern long-eared bat (Myotis septentrionalis), and the proposed endangered tricolored bat (Perimyotis subflavus)—which depend on continuous canopy structure for foraging and maternity roosts. The roadless condition also supports forest-interior bird species including the golden-winged warbler (Vermivora chrysoptera, near threatened) and eastern whip-poor-will (Antrostomus vociferus, near threatened), which require large, unfragmented patches of mature hardwood forest away from edge effects. Road construction would fragment this habitat into smaller, isolated patches, reducing the area available for these species and increasing predation and parasitism along newly created forest edges.

Climate Refugia Connectivity Across Elevation Gradients

Little Mountain's montane elevation (2,625–3,415 feet) and mixed hardwood–cove hardwood composition create a landscape mosaic that functions as a climate refugium for species sensitive to warming. The roadless condition preserves elevational connectivity that allows species like the eastern hemlock (Tsuga canadensis, near threatened)—already stressed by hemlock woolly adelgid—and rare high-elevation plants including small whorled pogonia (Isotria medeoloides, federally threatened) and Virginia spiraea (Spiraea virginiana, federally threatened) to shift their ranges vertically as temperatures change. This connectivity is difficult to restore once severed; roads create permanent barriers to species migration and fragment the microclimate gradients these species depend on for survival.

Rare Plant Communities and Pollinator Habitat

The area's diverse forest types—including Central Appalachian xeric chestnut oak–Virginia pine woodland and great rhododendron–mountain laurel thickets—support rare plant species including Epling's hedge-nettle (Stachys eplingii, critically imperiled), white alumroot (Heuchera alba, imperiled), and bentley's coralroot (Corallorhiza bentleyi, vulnerable). These plants depend on the rusty patched bumble bee (Bombus affinis, federally endangered) and monarch butterfly (Danaus plexippus, proposed threatened) for pollination. The roadless condition protects these plant communities from invasive species spread and maintains the undisturbed soil and light conditions these rare species require.

Threats from Road Construction

Sedimentation and Stream Temperature Increase from Canopy Removal

Road construction requires cutting slopes and removing forest canopy along the roadbed and in fill areas, exposing mineral soil to erosion. In Little Mountain's steep montane terrain, this exposed soil delivers sediment directly into the tributary network—Brush Run, Trout Run, Laurel Run, and others—where it smothers the gravel and cobble spawning substrate that candy darters require for reproduction. Simultaneously, canopy removal along stream corridors eliminates shade, allowing solar radiation to warm the water. Candy darters are cold-water specialists; even modest temperature increases reduce their metabolic efficiency and reproductive success. The combination of sedimentation and warming would render these headwater streams unsuitable for the species, directly undermining the critical habitat protections that currently apply to this drainage.

Habitat Fragmentation and Edge Effects on Forest-Interior Species

Road construction divides the 8,172-acre forest interior into smaller, isolated patches separated by the road corridor itself and the edge habitat (increased light, wind exposure, invasive species colonization) that extends inward from the road. Indiana bats, northern long-eared bats, and golden-winged warblers require continuous interior forest; fragmentation reduces the area of suitable habitat below the minimum needed to support viable populations and increases exposure to predators and parasites along the newly created edges. The road corridor itself becomes a dispersal pathway for invasive plants—garlic mustard, Japanese stiltgrass, and mile-a-minute weed—which spread from disturbed soil into the roadless interior, outcompeting native understory plants that rare species like small whorled pogonia and Virginia spiraea depend on. Once fragmented and invaded, this habitat is extremely difficult to restore to its original condition.

Culvert Barriers and Loss of Aquatic Connectivity

Road construction across stream channels requires culverts or bridges. Culverts—particularly undersized or perched installations—create barriers that prevent candy darters and other aquatic species from moving between upstream and downstream habitat sections. This fragmentation isolates populations, reducing genetic diversity and preventing recolonization of areas where local extinctions occur. In a headwater system like Brush Run–Greenbrier, where candy darters occupy multiple tributary streams, culvert barriers would isolate subpopulations and increase extinction risk across the entire critical habitat unit. Unlike sedimentation or temperature effects, which can theoretically be mitigated through restoration, culvert barriers are permanent features that require active removal to restore connectivity.

Invasive Species Establishment and Spread Along Road Corridors

Road construction creates a network of disturbed soil, compacted edges, and increased light availability—ideal conditions for invasive plants to establish and spread into the roadless interior. The documented invasive species threat (garlic mustard, Japanese stiltgrass, mile-a-minute weed) would colonize the road corridor and adjacent areas, outcompeting the native understory plants that support the rusty patched bumble bee and monarch butterfly, and degrading habitat for rare plants including Epling's hedge-nettle and white alumroot. Roads also facilitate human access, increasing the likelihood of unintentional seed dispersal and the introduction of new invasive species. In a landscape already stressed by hemlock woolly adelgid and other pests, the addition of invasive plant competition would reduce the resilience of rare plant communities and their associated pollinator networks.

Hiking and Trail Access

The Allegheny Trail (Forest Trail 701) passes through Little Mountain as a 330-mile north-to-south corridor, following the ridgeline and providing backcountry foot access to the interior. The Hosterman Trail offers additional hiking opportunity from the Hosterman Trailhead. These trails traverse steep mountain terrain ranging from 2,625 feet in Slavin Hollow to 3,415 feet at Little Mountain's summit, moving through mixed hardwood and oak-hickory forest. The roadless condition preserves the quiet, undisturbed character essential to backcountry hiking—the absence of internal roads keeps these ridgeline routes free from motorized use and maintains the forest's natural soundscape.

Fishing

The West Fork Greenbrier River, which forms the area's boundary, supports rainbow, brown, and brook trout and receives regular stocking from the West Virginia Division of Natural Resources. Internal streams—including Laurel Run, Trout Run, and Little River—support wild native brook trout and introduced populations. Laurel Run is particularly noted for its wild brook trout. The Candy darter, a federally endangered species, inhabits the Greenbrier River headwaters; anglers should dispose of unused bait in trash rather than water to prevent introduction of invasive species that threaten this fish. The Allegheny Trail provides foot access to these backcountry streams. All anglers 15 and older must carry a West Virginia fishing license and trout stamp. Sections of the West Fork Greenbrier River are managed as catch-and-release fisheries requiring artificial lures and flies only. The roadless condition preserves cold, clear, fast-moving headwater streams with some of the highest water quality in the state—conditions that would be degraded by road construction and the erosion, sedimentation, and thermal changes that follow.

Hunting

American black bear, white-tailed deer, and wild turkey are documented game species in the area. Ruffed grouse, gray and fox squirrel, cottontail rabbit, and snowshoe hare are also present. Bear archery and crossbow season runs September 27 – December 31, 2025; gun seasons occur in select windows between August and December. Deer archery and crossbow season runs September 27 – December 31, 2025; buck firearms season is November 24 – December 7, 2025. Hunters access the area via the trail system and gated forest roads. The dense Great Rhododendron and Mountain Laurel thickets provide heavy cover for game. The roadless condition is prized by hunters for backcountry solitude and the absence of permanent or temporary roads that would fragment wildlife habitat and increase human disturbance during critical hunting seasons.

Birding

The area's large contiguous hardwood forests support interior forest breeding species including Cerulean Warbler, Golden-winged Warbler, Wood Thrush, Ovenbird, Scarlet Tanager, Worm-eating Warbler, and Ruffed Grouse. Broad-winged Hawk, Hairy Woodpecker, Eastern Wood-Pewee, Great Crested Flycatcher, Blue-gray Gnatcatcher, and Yellow-throated Vireo are also documented. Spring and fall migrations bring neotropical warblers and raptors along the Appalachian ridges. Breeding season supports "Alleghenian zone" species including Blue-headed Vireo, Dark-eyed Junco, and Magnolia Warbler. The Allegheny Trail and internal forest provide access for observation. The roadless condition preserves unfragmented interior forest habitat critical for breeding warblers and other species sensitive to edge effects and forest fragmentation that roads would create.

Photography

The Allegheny Trail follows Little Mountain's ridgeline, offering scenic views of forested hillsides and the surrounding mountainous terrain. The summit of Little Mountain (3,415 ft) and Sandy Ridge provide vistas across the landscape. The trail passes near the Green Bank Observatory, offering unique perspectives of the observatory's structures against the forest backdrop. Named streams including Laurel Run, Trout Run, Allegheny Run, Brush Run, Cup Run, Deever Run, Spillman Run, and Wanless Run provide coldwater stream and riparian photography subjects. Great Rhododendron and Mountain Laurel thickets display significant floral blooms in late spring and early summer. Rare plants documented in the area include Bentley's coralroot, Fraser's Sedge, and Epling's Hedge-Nettle. Wildlife subjects include American black bear, white-tailed deer, bobcat, red fox, Cheat Mountain salamander, Indiana bat, and Northern long-eared bat. Brook trout and Candy darter offer specialized aquatic photography opportunities. The area lies within the National Radio Quiet Zone surrounding Green Bank Observatory, which often coincides with minimal light pollution suitable for night photography. The roadless condition preserves the dark sky conditions and undisturbed forest character that make scenic and wildlife photography possible without the visual and acoustic intrusion of roads and vehicles.
