Mid-Atlantic HighlandsMid-Atlantic Highlands

From the Housatonics in Connecticut to the Michaux State Forest in Pennsylvania, the Mid-Atlantic Highlands region of New York, New Jersey, Pennsylvania, and Connecticut forms a 3.5 million acre greenbelt around the sprawling areas of Philadelphia, New York City and Hartford.

The Mid Atlantic Highlands are part of the Appalachians. The region is located from south-central Pennsylvania through New Jersey and New York to northwestern Connecticut, forming a vital linkage between the Berkshires to the north and the Blue Ridge Mountains of the south.

Here, forested ridges make up rolling hills and mountains of green across the horizon. There are many lakes, ponds, streams, rivers and reservoirs. Rocky crags and deep forest offer wild and untamed habitat to a large variety of wildlife. There are clear cold streams in which native trout breed, and the forests are home to black bear, river otters and bobcat. More than 14 million people visit the Highlands annually, more than Yellowstone and Yosemite National Parks combined.

The Mid Atlantic Highlands are seen as "a landscape of national significance," by the US Forest Service, and as a "Special Resource Area" by the State of New Jersey, vital open spaces in the Highlands are increasingly being lost to suburban sprawl, including over 5,000 acres annually in the NY-NJ Highlands alone. The future of this region of water, beauty and life is in jeopardy.

The "backyard" to the New York-Philadelphia-Hartford metropolitan area, the Mid-Atlantic Highlands offer more than 200,000 acres of public open space, these Highlands host more than 14 million recreational visits annually.

Several trails traverse the region, including the Appalachian Trail, Long Path and Highlands Trail.

Over 100 plants and almost 50 animals listed as Federal or State endangered, threatened or species of concern make their home in these Highlands.

The region provides critical wildlife habitat for more than 70 species of migratory songbirds and species such as black bear, bobcat, beaver, otter, and trout.

Other Areas

Schenob Brook Watershed (Litchfield Co.)
One of the finest calcareous fens in New England. The 2230 acres of the main wetland portions of the lowland swamps have remained undeveloped and were nominated for designation as a federal area of environmental concern in 1990.

Canaan Lime Cliffs (Litchfield Co.)
Carbonate bedrock is rare in New England, restricted to relatively small portions of western Vermont, Massachusetts, and Connecticut. Many unusual plants and wildlife rely on the calcium-rich soils and limestone outcrops in the Highlands.

Canaan Mountain (Litchfield Co.)
The higher elevations of Canaan Mountain are owned by relatively few owners with large landholdings. The Connecticut Department of Environmental Protection has purchased considerable acreage and has recently expressed interest in protecting approximately 1123 water company acres. Additionally, the Yale School of Forestry operates a demonstration forest with the permission of one landowner.

Farmington River Wild and Scenic Area (Litchfield Co.)
The Farmington River Wild and Scenic Area winds through the Highland towns of Colebrook, Hartland, Barkhamsted, New Hartford, and Canton.

Housatonic River Greenway (Litchfield Co.)
This corridor has been officially designated a Greenway by the State of Connecticut. It extends from the Highlands region to the Long Island Sound.

Macedonia Brook Watershed (Litchfield Co.) The watershed of Macedonia Brook encompasses several thousand acres of unbroken forest. The Macedonia State Park provides a foundation for additional land protection to provide extensive fish and wildlife habitat.

Stanley Works Scenic Area (Litchfield Co.) This tract along the east shore of the Housatonic River encompasses approximately 600 acres in the towns of Cornwall and Kent. Although a portion of the tract is protected under a federal scenic easement, the two towns, local land trusts, and the Connecticut Department of Environmental protection are working to preserve the entire parcel.

Shepaug Watershed (Litchfield Co.)
Until the late 1970s, the City of Waterbury permitted a stretch of the Mattatuck Trial to pass through several thousand acres of watershed lands associated with the Shepaug Reservoir. Permanent protection of these lands along with reopening the trail would guarantee water quality along with the potential to create linkages to the Shepaug River Greenway.

Bull’s Bridge Scenic Area (Litchfield Co.)
The Bull’s Bridge hydropower Development, located in the towns of Kent and New Milford. Protecting these lands would augment 400 acres of federally-protected Appalachian Trial corridor. This unusually large undeveloped forested riparian area contains numerous critical habitats for rare species.

Shepaug Greenway (Litchfield Co.)
Extending along the river from its source to the confluence with the Housatonic River, the area protects open spaces and important habitats in the Shepaug River watershed. This corridor has been officially designated a Greenway by the State of Connecticut.

Other Areas in PA

Bougher Hill (Northampton Co.)
Bougher Hill is the site of the Mariton Wildlife Preserve and consists of meadows, forested rocky ridges, woodlands and springs. These resources serve as habitat for woodland birds and breeding areas for amphibians. The Preserve features a nature center and affords an excellent view of the Delaware River.

Durham Mine/Mine Hill/Rattlesnake Hill (Bucks Co.)
This ridge represents a spur of the Reading Prong separated from the main mass of the Prong by the limestone valley containing Cooks Creek. The site consists of extensive north-facing forested slopes extending for about two miles. Iron ore from Mine Hill supplied the early forge at Durham. The abandoned mine has become the second largest bat hibernaculum in Pennsylvania. The 150-175-acre forest that covers the slopes of Mine Hill and Rattlesnake Hill provides habitat for 62 bird species, including ten rare breeders.

Haycock Mountain (Bucks Co.)
The State Game Lands (#157) on Haycock Mountain and Nockamixon State Park together constitute the largest expanse of protected open space in Bucks County (7,000 acres). Three rare plant species and 47 species of birds, including five rare breeders, make their home on the diabase outcrops and forests of the Mountain.

Lower Lehigh Valley Reach of the Lehigh River (Northampton & Lehigh Co.) formerly named Lehigh Canal & Corridor Greenway
The 15-mile reach of the Lehigh River that runs east from Allentown through Bethlehem to its confluence with the Delaware River in Easton has a remarkably wild aspect in spite of the fact it runs through the urban heart of the beautiful Lehigh Valley. This reach defines the precise edge of the core of the Pennsylvania Highlands – South Mountain.

South Mountain (Northampton Co.)
South Mountain is the name given locally to the ridge of hills extending from Easton to Reading, a distance of some 45 miles. The hills are wooded and rolling, with some cleared areas for farming and increasing residential development. Much of the present water supply for a number of communities in eastern Pennsylvania flow from these hills, including the city of Allentown.

Hosensack Swamp (Lehigh Co.)
This 100-acre wetland in the Hosensack Valley contains established populations of rare and endangered animals and was given the highest priority rank in the Lehigh and Northampton County Natural Areas Inventory.

Unami Hills and Ridge Valley Creek (Montgomery & Bucks Co.)
The Unami Hills region of northern Montgomery County is part of a diabase rock formation that stretches across Bucks and Montgomery Counties. These rocky, wooded ridges form a conspicuous band of forest two to three miles wide from the Delaware River to central Montgomery County, including the Unami Creek Valley and that of the adjacent Ridge Valley Creek. The diabase zone constitutes the largest contiguous tract of forest remaining in these two counties, and provides important habitat for forest interior birds such as pileated woodpeckers, songbirds and other species that require large blocks of unfragmented forest.

Mt. Penn & Neversink Mountain (Berks Co.)
Mt. Penn and Neversink Mountain provide a scenic backdrop for the city of Reading, located at the southwestern tip of the Reading Prong. Long considered a natural and recreational area for the Reading region.

Stone Hill (Montgomery Co.)
Stone Hill, sister mountain to Spring Mountain, is the beginning of a wooded landscape that densely covers Marlborough and Salford Townships in Montgomery County, and a portion of Bucks County.

Great Marsh (Chester Co.)
Chester County’s Great Marsh is part of the Delaware River watershed and consists of over 3,400 acres in the townships of East Nantmeal, West Nantmeal and Wallace. The Great Marsh is the largest, most biologically rich inland freshwater marsh in the eastern part of the state; the Commonwealth of Pennsylvania classifies it as an Important Bird Area and an Exceptional Value wetland. 155 bird species live here including the short-eared owl (state endangered), least bittern (state endangered), pied-billed grebe, marsh wren and Wilson’s snipe. The Great Marsh serves an important migration corridor with over 30 warbler species (including the prothonotary warbler, Cape May warbler, palm warbler, bay-breasted warbler, Wilson’s warbler and Canada warbler) passing through. In addition, the area is important for Pennsylvania Species of Special Concern such as the black dash butterfly, mulberry-winged skipper. Deer, muskrat, fox and mink live here also.

Historically, Great Marsh was burned by Native Americans and later farmed by early colonial settlers.

The potential for recreation here is great with opportunities for hiking, canoeing, biking, birding and hunting.

Welsh Mountain (Lancaster Co.)
Welsh Mountain is a long ridge in eastern Lancaster and northwestern Chester counties that rises about 1,000 feet above Amish farmland.

Furnace Hills (Lancaster Co.)
The Horseshoe Trail extends the length of the Furnace Hills and serves as a major recreational attraction. The trail was once used to transport goods to and from the numerous iron furnaces and forges in the Pennsylvania Highlands. State Game Lands in the Furnace Hills also provide outdoor recreation activities such as hiking, boating, fishing and hunting.

Narrows (Adams Co.)
The Narrows, one of Adams Co.’s most scenic areas, consists of about 3000 acres of quality forest habitat with mossy seeps and many older hemlocks and white pines on the higher slopes. It is named for its water gap, which reaches 680 feet and contains gray-green metarhyolite outcrops which support several plant species of conservation concern.
