Resilient and Connected Plains

How we're saving nature's stage in the Great Plains.

Nature is on the move as warmer temperatures, increased flooding and other climate impacts alter and destroy habitat, forcing species to search for new places to live. As nature faces growing threats, so do people who rely on healthy lands and waters for food, jobs and quality of life.

The Resilient and Connected Network

Working with non-government, government and academic partners, scientists at The Nature Conservancy (TNC) have identified and mapped a network of lands across the United States with unique topographies, geologies, and other characteristics that can withstand climate impacts, called the Resilient and Connected Network.

This roadmap of “natural highways and neighborhoods” shows where plant and animal species have the best chance to move away from growing climate threats and find new places to call home.

Give Them Room to Roam

As our changing climate continues to take a toll on wildlife habitat, we're working on ensuring safe and resilient natural highways for migrating wildlife.

Black Hills

The Black Hills in South Dakota 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 the Black Hills is home to rare plants and is one of the best places in the region for birdwatching.

Blackland Prairies

The blacklands of southwestern Arkansas, a landscape dominated by tall native grasses and vibrant wildflowers, harbors more than 600 types of plants, including 21 globally imperiled plant communities. Originally about 12 million acres of these prairies and woodlands covered parts of Arkansas, Texas, Louisiana, Mississippi and Alabama. Today, only some 10,000 acres remain in scattered patches. TNC is working with partners and private landowners to restore blackland sites in the Natural State.

Davis Mountains

The Davis Mountains in western Texas 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.

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. In Kansas, Konza Prairie and Tallgrass Prairie National Preserve are open to the public and TNC also works with private landowners to preserve their land.

Oklahoma Canyons

Prairies and grasslands are some of North America’s most threatened and ignored habitats suffering from land fragmentation, encroachment of invasive species and conversion of native grasses to cropland. The Four Canyon Preserve in western Oklahoma spans 4,050-acres of rugged short-grass prairie along the banks and floodplain of the mighty Canadian River. This preserve protects the charismatic Texas horned lizard, better known as the horny toad, Cassin’s sparrow as well as important plants for pollinators such as blue indigo, prairie coneflower, prairie blazing star and common milkweed.

Loess Hills

Fine particles of windblown silt, known as loess, created the Loess Hills as glaciers retreated at the end of the last Ice Age. Today, the 650,000-acre Loess Hills landscape rises 200 feet above the Missouri River valley and is recognized for its unusually deep deposits of loess. Iowa's largest surviving prairies are found in the Loess Hills and TNC's Broken Kettle Grasslands Preserve. TNC hopes to preserve more than 100,000 acres in the Loess Hills to maintain healthy ecological systems within a sustainable, working agricultural landscape.

Meramec River

Among the longest free-flowing rivers in the U.S., the Meramec River in Missouri 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.

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.

Nebraska Sandhills

The Nebraska Sandhills encompass approximately 19,300 square miles of sand dunes, stretching 265 miles across Nebraska. It one of the largest contiguous, intact grasslands in all of the United States. Ranching has proven to be the best economic and environmental use of the Sandhills, and TNC works alongside ranchers on invasive species removal and prescribed fire training.

Superior National Forest

Encompassing the Boundary Waters Canoe Area Wilderness, 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.
