Resilient and Connected Landscapes
This Story Map highlights climate-resilient sites across the continental US that collectively represent the extraordinary natural diversity of the country. Each of these sites have unique topographies, geologies, and other characteristics that can help withstand climate impacts and keep nature safe in the face of climate change. This Resilient and Connected Network of lands was identified and mapped over a 10-year period by Nature Conservancy scientists using public data available at the state and national scale. More than 150 scientists from agencies, academia and NGOs across the US were involved in this process. If conserved, these “natural highways and neighborhoods” offer a chance of sustaining biological diversity into the future while helping species to move and adapt to a changing climate.
The Resilient and Connected Network is a starting point for conversations with local communities, Indigenous communities, land trusts, agencies, corporations and funders on how we can coordinate our conservation efforts to increase our collective impact and sustain nature. Resilient lands and waters may be conserved by a wide range of measures from good land stewardship, to other forms of private land conservation, to outright fee or easement acquisition by various levels of government.
Network Stats:
· Covers 33% of the continental US
· Encompasses multiple resilient examples of every geophysical habitat
· Contains over 250,000 known occurrence of significant biodiversity features
· Is configured to facilitate range shifts and migrations by species
· Stores over 3 billion tons of carbon: 56% of all forest carbon in the US
· Is 44% secured against conversion to development
The resilient and connected network map (shown in green below) is composed of three essential ingredients:
Climate Resilient Sites: ecologically representative sites with a diversity of connected microclimates.
Connectivity and Climate Flow: Linkages that allow species to move across sites and climate gradients.
Recognized Biodiversity Value: Places with intact habitats, rare species, or exemplary communities.
01 / 48
1
Alabama: Sharp Bingham Preserve/Paint Rock
For millennia, rains have carved more than 55 caves that now contain extraordinary animals unique to the Southern Cumberland Plateau. The Nature Conservancy has preserved almost 4,000 acres in the Paint Rock River Landscape that protect this subterranean ecosystem as well as the steep cliffs and deep forests that overlay it. The combination of cave species, rare plants, and nesting migratory birds makes the Sharp-Bingham area a biological treasure trove of nationwide importance.
2
Arizona: The Verde River
The Verde River is one of Arizona’s natural climate corridors, providing flowing waters and habitat that protect biodiversity, connecting wildlife corridors and migratory bird flyways, and in the future will provide a migratory pathway northward as temperatures rise. Along with supporting nature, the River provides 3 million people with drinking water, farm irrigation, and recreation. Working with partners, TNC is keeping more water in the river with new economic markets and improved water management.
3
Arkansas: Blackland Prairie Region
The blackland prairies and woodlands of southwestern Arkansas harbor more than 600 species of plants (including 21 globally imperiled plant communities) and some 315 animal species. While some 12,000 acres are already protected, TNC is working with partner agencies and private landowners to protect additional lands and boost habitat-management efforts.
4
California: Amargosa Region of the Mojave Desert
The Mojave Desert's Amargosa River basin supports many rare and unique species and habitats, like mesquite bosques, seeps and marshes. Nearly 50 species are found nowhere else on Earth. Though largely in public ownership, TNC and partners are working to reduce threats to wildlife and restore critical habitats.
5
Colorado: Southern High Plains
Southeastern Colorado and surrounding states hold some of the world's greatest remaining grassland ecosystems. Once harboring legions of bison and myriad grassland birds, large areas of prairies have been altered by cropland conversion, wind energy and invasive species. But much of the region remains intact and TNC and partners have protected places like JE Canyon Ranch and Fishers Peak to help retain long-term resilience.
6
Connecticut, Massachusetts: Berkshire Wildlife Linkage
The Berkshire Wildlife Linkage is a natural highway connecting the Green Mountains in Vermont to the Hudson Highlands in New York. The Conservancy has been working with partners to protect more than 20,000 acres across this area. The effort is aimed at linking core forest habitats by protecting corridors, allowing wildlife to migrate as climate change shifts temperature zones.
7
Delaware: Delaware Bayshore
Delaware’s Bayshore landscape is a mosaic of undeveloped beaches and dunes, shifting shorelines, vast tidal marshes, upland forests and open farmland. More than a million migratory shorebirds visit the area each spring to feed on eggs laid by spawning horseshoe crabs. At its Milford Neck Preserve, The Nature Conservancy is restoring marshes and forests to help keep the coastal area resilient to climate impacts.
8
Florida: Apalachicola
Globally recognized for plant diversity, the Apalachicola National Forest is one of North America's top five biodiversity hotspots and is the largest national forest in Florida. Adding to the forest's plant and wildlife diversity are its caverns, sinkholes and extensive longleaf pine and wiregrass natural community. The Conservancy’s Apalachicola Bluffs and Ravines Preserve is just north of the national forest.
9
Georgia: Altamaha River Corridor
One of the largest undammed rivers in the East, the Altamaha River drains more than one-fourth of the state and its tributaries provide drinking water from Atlanta to middle Georgia. For over 20 years, The Nature Conservancy and partners have created a 42-mile-long corridor of protected land along the river . Islands and salt marshes in Altamaha Sound are a nursery for microbes, shrimp and fish.
10
Idaho: St. Joe-Clearwater Landscape
St. Joe-Clearwater lands are at the heart of an expansive network of Inventoried Roadless and Wilderness areas spanning millions of acres in north-central Idaho and provide critical connectivity for wildlife in the Northern Rockies. Part of the Crown of the Continent Ecosystem, public lands and unprotected inholdings support healthy populations of mountain goat, elk, moose, black bear, and mountain lion along with a complex fishery that includes bull trout and westslope cutthroat trout, and the St. Joe River is designated Wild and Scenic. Immense pressure from population growth and development is threatening St. Joe-Clearwater forests essential for maintaining this climate resilient network and enormously important for carbon storage and Idaho’s timber economy.
11
Illinois: Midewin National Tallgrass Prairie
The U.S. Forest Service’s Midewin National Tallgrass Prairie is the largest tallgrass prairie restoration effort east of the Mississippi River and provides refuge for many common and rare bird species. Midewin’s sheer size provides opportunities to foster a variety of habitats required by many species, particularly those that require wide open spaces.
12
Indiana: Sugar Creek Corridor
Deep ravines, canyons and cliff faces characterize the landscape within the Sugar Creek valley in west central Indiana. TNC has been working in the area for more than 50 years to enhance water quality in Sugar Creek by protecting the relatively large forest blocks surrounding it.
13
Iowa: Loess Hills
Western Iowa’s Loess Hills are a globally unique formation of deep soil deposits. This 640,000-acre landscape has tremendous diversity of plants and animals and holds more than half of Iowa’s remaining tallgrass prairie habitat. The abundant habitat and connectivity of protected lands here, along with “peak and saddle” topography, make it one of the region’s places most resilient to climate change.
14
Kansas: Flint Hills
Originally spanning portions of 14 states from Canada to the Gulf of Mexico, today less than 4% of world’s tallgrass prairie remains—and most found in the Flint Hills of eastern Kansas and northern Oklahoma. Here, four million acres of deep-rooted grasses in the Flint Hills nurture some the greatest biological diversity in the world.
15
Kentucky,Tennessee, and Virginia: Cumberland Forest Project
Spanning 253,000 acres across Tennessee, Kentucky and Virginia, the Cumberland Forest area not only safeguards critical wildlife habitat but also fights climate change. Its forests store millions of tons of carbon dioxide and because its complex geology has created numerous microclimates, the region provides "escape routes” for plants and animals fleeing climate impacts in searching of new places where they can thrive.
16
Louisiana: Atchafalaya River Basin
At 1.4 million acres, the Atchafalaya River Basin is North America's largest floodplain swamp. Aside from the basin's many natural services (like flood control, nutrient sequestration and carbon storage), its cypress-tupelo forests, fertile marshes, and meandering bayous provide essential habitat for more than 300 species of wildlife, 100 aquatic species, and a rich diversity of native plants.
17
Maine: Boundary Mountain Preserve
TNC's new 9,600-acre Boundary Mountains Preserve is a treasure of diversity and resilience. Adjacent to over 22,000 acres of public lands in Quebec, the preserve extends a corridor of conserved lands northward to more than 260,000 acres. This represents a key link in a major ecological pathway from the White Mountains through western Maine mountains and Quebec. It holds a dozen peaks over 2,700 feet in elevation.
18
Maryland: Pocomoke River
A classic coastal migration corridor, the Pocomoke drains water from Delaware, Maryland, and Virginia into the Chesapeake Bay. The Pocomoke's cypress swamp forests and wetlands that are fed by natural flooding patterns are biodiversity hotspots supporting 60-plus migratory songbirds. The river harbors numerous resident and migratory fish species, including herring and shad. TNC and partners are restoring floodplains along 18-miles of the river – the largest ecological restoration project in Maryland’s history.
19
Massachusetts: Schenob Brook
At more than 2,500 acres, Schenob Brook Preserve is important for its diverse and rare flora and fauna and unique calcareous wetlands. Protected lands here include the Schenob Brook wetland complex and upland acreage to the west that is wetlands' water source.
20
Michigan: Michigamme Highlands
The Michigamme Highlands are located within some of the largest remaining unbroken swaths of hardwood forest in North America. These rich forests moderate regional climate, store carbon, filter the headwaters of the Great Lakes, provide wildlife habitat and support timber, recreation and tourism. The Nature Conservancy’s Wilderness Lakes Reserve, located within the Michigamme Highlands, is managed as an active forest reserve, demonstrating sustainable forestry practices and enrolling the property in carbon markets.
21
Minnesota: Superior National Forest
Encompassing the Boundary Waters Canoe Wilderness Area, the large blocks of contiguous forest within Superior National Forest are ideal for Minnesota’s moose, wolves and migratory songbirds as well as sustainable timber harvests. TNC is planting millions of trees in the region with climate change in mind to ensure our forests will remain diverse and resilient.
22
Mississippi: The Pascagoula River
The largest free-flowing river in the continental US, the Pascagoula River is buffered by an 80,000-acre bottomland hardwood corridor of public and private conserved lands. Realizing its significance, TNC purchased 35,000 acres along the Pascagoula River in 1974 -- the largest land acquisition in its history at that time. That land later became the Pascagoula Wildlife Management Area (WMA) which supports over 300 wildlife species
23
Missouri: Meramec River
Among the longest free-flowing rivers in the U.S., the Meramec River is an irreplaceable freshwater resource and key tributary to the Mississippi River. Its well-protected watershed supports among the highest biodiversity in the region, provides economic and recreational resources for local communities, and clean drinking water to approximately 70,000 households.
24
Montana, Wyoming, Idaho: Greater Yellowstone Ecosystem
The Greater Yellowstone is the source of seven major rivers, home to our country’s first national park and a convergence of forests, sagebrush, grasslands and geothermal wonders. The area is a patchwork of private and public lands that support animals found few places on the planet and which provide critical seasonal habitat to migrating elk, pronghorn and mule deer.
25
Nebraska: Niobrara Valley Preserve
The 56,000 acre Niobrara Valley Preserve is a biological crossroads of the Great Plains. Its variety of conserved habitats provide lasting resilience, with six different ecological types: northern boreal, western coniferous, and eastern deciduous forest and mixed grass, tallgrass, and sandhills prairie. To date, 581 plant, 213 bird, 86 lichen, 70 butterfly, 44 mammal, 25 fish, 17 reptile and 8 amphibian species have been recorded at the preserve.
26
Nevada: Monsoon Passage
The connected mountain ranges and wet valley bottoms of this natural highway provide desert tortoises, bighorn sheep, Cooper’s hawk, mule deer, golden eagles and other species escape routes from growing climate impacts, allowing them to find new homes where they can thrive. The region's name comes from being at the western edge of the summer monsoons that provide eastern-facing moisture to buffer rising temperatures and a pathway for species moving north.
27
New Hampshire: Southern Greens to the White Mountains
The vast and diverse area between the southern Green Mountains in Vermont, through the Monadnock Highlands and the White Mountains in New Hampshire is a critical link for lasting resilience. As climate change continues to drive a northward shift in many species, this region will be important for enabling new species such as the marbled salamander and Eastern box turtle to move into southern New Hampshire.
28
New Jersey: Bobcat Alley
Bobcat Alley , a 32,000-acre forested corridor in Northwestern New Jersey providing prime habitat for state-endangered bobcats and other wildlife, is a critical land-link connecting vast forested Central Appalachians regions to protected areas in the Catskills and northward, where many species are projected to move as the climate changes.
29
New Mexico: Gila River
The Gila River and its floodplain are a resilient corridor of habitat connecting verdant mountain forests to desert lowlands.
30
New York: Follensby Pond
Nestled between wilderness areas of the Adirondacks, Follensby Pond provides a protected corridor and refuge for a vast array of wildlife. Follensby is the largest of only nine remaining intact lakes in the lower 48 states that support what Cornell University has coined an “old growth” lake trout population along with other species listed as Greatest Conservation Need in New York.
31
North Carolina: Longleaf Pine Sandhills Region
The Sandhills of North Carolina are more resilient to a changing climate and will be an important refuge for plants and animals of the longleaf forest. The Uwharrie mountain region to the west also has high climate resilience and could offer safe passage for some species as the climate changes.
32
North Dakota: Missouri Coteau
The Missouri Coteau includes much of the Prairie Pothole Region, regarded as America’s duck factory because its prairies and wetlands create ideal habitat for nesting waterfowl. TNC’s 7,000+ acre Davis Ranch in North Dakota is being managed for not only ducks but also pollinators and grassland birds.
33
Ohio: Edge of Appalachia Preserve System
Encompassing over 20,000 acres in southern Ohio, the Edge of Appalachia Preserve System consists of 11 contiguous preserves owned and managed by TNC and the Cincinnati Museum Center. It has been called the "crown jewel” of biological diversity in Ohio, with more than 100 rare plant and animal species, including Indiana bat, green salamander and Allegheny woodrat. Future conservation projects can create larger links for resident and migrating wildlife.
34
Oklahoma: Four Canyon Preserve
TNC's Four Canyon Preserve encompasses 4,000 acres of mixed-grass prairie, rugged canyons, and floodplain along the Canadian River. Scenic prairie ridges traverse the landscape, dissected by deep chinquapin oak-lined canyons draining to the river. The prairies and contrasting wooded canyons provide varied habitat for a variety of plant, bird and wildlife species that can be resilient as climate changes.
35
Oregon: Sycan Marsh and Surrounding Forests
The Sycan Marsh Preserve is a vast wetland in the upper reaches of the Klamath Basin, nestled within many thousands of acres of dry forests. Sycan is located within the ancestral homelands of the Klamath, Modoc, and Yahooskin, collectively The Klamath Tribes. Located on the Pacific Flyway, the marsh is home to thousands of birds and provides habitat for endangered fish. Thanks to the Preserve’s landscape, it is also an epicenter of fire ecology and forest & fire management research. For years, TNC has been working with Indigenous people, forest ecologists, and fire practitioners to conduct prescribed burns, study fire behavior, and collect data on everything from air quality to the ways in which fire and climate change impacts forest conservation and restoration efforts.
36
Pennsylvania: Kittatinny Ridge
Running 185 miles from the Mason-Dixon Line to the upper Delaware River, the Kittatinny Ridge harbors a huge array of species including bobcats, black bear, broad-wing hawks and nine species of bats. The Nature Conservancy is working to ensure this important migratory corridor remains intact, healthy and resilient to climate impacts.
37
Rhode Island: Pawcatuck Borderlands
The Pawcatuck Borderlands is part of a natural highway that connects the coastal habitats of southern Rhode Island to the mountain habitats of northern New England and beyond. At the heart of this area are four forest blocks that form a relatively undeveloped “oasis” in the middle of the highly developed coastal corridor from DC to Boston.
38
South Carolina: Nine Times Preserve
Nine Times Preserve lies at the intersection of South Carolina’s Southern Blue Ridge Mountains and its piedmont region, where mountainous terrain begins to slope into gentler hills. Black bear, peregrine falcons and freshwater trout are just a few of the species you may find on this incredibly biologically significant property, which also features more than 130 species of native wildflowers, five mountain summits and seven distinct forest types.
39
South Dakota: Black Hills
The Black Hills is an ecologically unique and important area for conservation. Sitting at the confluence of sage lands, pine forests and mixed grasslands, its diverse habitat attracts an array of wildlife including mountain lions and bighorn sheep. TNC’s Whitney Preserve in South Dakota is home to rare plants and is one of the best places in the region for birdwatching.
40
Tennessee: Hatchie River
The Hatchie River is the longest naturally meandering river left in the Lower Mississippi Valley and contains the largest forested floodplain in Tennessee. Because it has remained undammed and largely unchannelized, the natural flood processes that drive the ecosystem are intact, sustaining the river and wetland habitats that support a rich ecological diversity. The Hatchie River ecosystem encompasses bottomland hardwood forests, canebrakes, swamps, sloughs, rivers and lakes.
41
Texas: Davis Mountains
The Davis Mountains are called a “sky island” because they rise abruptly from the surrounding Chihuahuan desert. This cooler and wetter oasis provides habitat for plants and wildlife unable to live in the desert. The mix of forests, grasslands, canyons, and creeks provides opportunities for many species to find suitable conditions, even in a changing climate.
42
Texas: Central Hill Country
Crystal clear water flows through the deep, cool canyons of Texas Hill Country streams like Love Creek , many of which contribute to aquifers used for drinking water. These spring-fed waters and the varied habitats on the uplands enable a wide variety of native plants and wildlife – from salamanders to golden-cheeked warblers – to flourish on the Edwards Plateau.
43
Utah: Colorado Plateau – Canyon Lands Province
The Canyon Lands province of the Colorado Plateau is a spectacular array of geologic formations and diverse vegetation from low-elevation grassland and desert shrublands to pinyon-juniper woodlands in higher elevations. An extensive resilient and connected network of landscapes, bolstered by vast public lands, makes this region valuable habitat for wildlife such as elk, mule deer, antelope, mountain lion, coyote, fox, and bobcat.
44
Vermont: Burnt Mountain
Aside from being Vermont's largest carbon storage project, the nearly 5,500-acre Burnt Mountain preserve is part of an 11,000-acre forest block that is permanently protected. Its varied topography, healthy forests and clear streams provide many long-term options for plants and animals to find refuge as climate changes.
45
Washington: Hoh River
From the glaciated peaks of Olympic National Park, the Hoh River runs through lowland rainforests to the Pacific Ocean. The Hoh Tribe has long stewarded these lands, which store immense amounts of carbon and host one of the healthiest wild salmon runs in the lower 48 states. The Conservancy seeks to grow the region’s climate resiliency by protecting and restoring habitat corridors along the length of the river.
46
West Virginia: Canaan Valley and Dolly Sods
Dolly Sods , the highest elevation plateau in the Appalachians, sits adjacent to the Canaan Valley, which is the highest elevation major Appalachian valley (and largest wetland complex in the Central Appalachians). These high elevations harbor spectacular views and a range of species and ecosystems that have persisted here since the end of the last ice age 14,000 years ago. The area includes TNC's Bear Rocks Preserve.
47
Wisconsin: Kettle Moraine region
Wisconsin’s Kettle Moraine region was shaped by glaciers during the last ice age and contains a wide range of glacial topographic features from large kettle lakes to 300-foot-high ridges. This north-south corridor, with varied terrain and microclimates and a diverse collection of plant communities including oak woodlands and savannas, prairies, bogs and fens, will be important for maintaining biodiversity as species adjust to climate change.
48
Wyoming, Montana, Idaho: Greater Yellowstone Ecosystem
The Greater Yellowstone is the source of seven major rivers, home to our country’s first national park and a convergence of forests, sagebrush, grasslands and geothermal wonders. The area is a patchwork of private and public lands that support animals found few places on the planet and which provide critical seasonal habitat to migrating elk, pronghorn and mule deer.
