What are Prairie Remnants and Prairie Restorations?

In our sprawling Metroplex, it can be hard to discern what was our “natural” landscape. With our mix of heavily developed land, artificial lakes, and small pockets of parks and nature preserves, it is challenging to see what was indigenous.

Upside-down Forests

So, what did our area look like before Europeans began settling the land? Prior to the arrival of Europeans, all of North Texas was part of 250+ million acres of tallgrass prairie, stretching from central Texas, running along the boundary of the Rockies, up to the Canadian plains, and east to Indiana.

There was incredible diversity; the North American Prairie could have 250+ species of plants in a localized area. While more vertically challenged than forests, the native prairies have been termed “upside-down forests” for the grasses’ deep root systems. These extensive root systems allowed our native prairie plants to be drought resistant and adaptable to the vicissitudes of the weather.

Deep Topsoil – The Prairie’s Double-edged Sword

These deep root systems benefited from a deep layer of topsoil. The North American prairie began to form around 20 million years ago from sediment washed down from the Rockies and glaciers, along with windblown deposits of material into what was once a great inland sea.

This process created a rich layer of topsoil on top of the former seabed. A prairie can hold as much as 250 tons of topsoil per acre, compared to only 50 tons for a forest.

When Europeans arrived, they quickly utilized the soil’s richness for extensive farming throughout the region. However, the creation of our continent’s “breadbasket” has resulted in the near-extinction of the native prairie. Only about 0.5% of the native prairie remains, and it continues shrinking.

A Movement to Reverse the Decline

Starting in the 1930s, a movement began to reestablish native prairies due to the damage inflicted during the Dust Bowl era. This movement has continued across North America with a dual focus on restoring native prairies and preventing further loss of remnant portions of virgin prairies. While they are similar, there are essential differences between prairie restorations and remnants:

  • Prairie restoration projects aim to convert a previously tilled or otherwise disturbed parcel of land back to near its pre-agriculture condition.
  • Prairie remnants are a piece of land that has not been disturbed by agriculture or development and is still in or very close to its pristine condition.

Restorations attempt to turn back the clock on the land. But the reality is that the complexity of the North American prairie biome makes a complete transformation unrealistic, especially on heavily disturbed soil. This results in fewer species than a prairie remnant but still far more variety than cultivated land.

This problematic fact highlights the criticalness of preserving remnants, as restorations are not a replacement for saving virgin prairies and their unique characteristics. But restorations are vital, as they complement our few remaining remnants and help restore the beauty and healthier ecosystem of native prairies.

Prairie Remnants and Restorations in North Texas

Here in North Texas, we have a wide variety of prairie remnants along with many ongoing prairie restoration projects. Below are some notable local prairie remnants and restorations, listed by county.

For more information on other local prairie remnants and restorations, please see a more complete listing from the Blackland Chapter of the Native Prairie Association of Texas.

Lastly, prairie restoration projects do not need to include hundreds of acres to be valuable. Creating a native prairie in your yard is relatively just as important to our North Texas ecosystem. By taking this vital step, you help create awareness of native prairie plants, enrich your local fauna, beautify your neighborhood, and continue the movement to bring back our native prairies.

About the Region

Fall Symposium 2025 Logo - Teach for the Future

Salado, the location of our Fall 2025 Symposium, lies at the intersection of two ecoregions: the Edwards Plateau (Limestone Cut Plain) and Blackland Prairie (Northern Blackland Prairie).

The Edwards Plateau area is also called the Hill Country; however, this general term covers a much larger area extending farther north. Spring-fed creeks are found throughout the region; deep limestone canyons, rivers, and lakes (reservoirs) are common. Ashe juniper is perhaps the most common woody species found throughout the region. Additional woody species include various species of oak, with live oak (Quercus fusiformis) being the most common. Sycamores (Platanus occidentalis) and bald cypress (Taxodium distichum) border waterways. This area is well known for its spring wildflower displays, though they may be viewed in spring, late summer, and fall, as well. According to Texas Parks and Wildlife, average annual rainfall in the Edwards Plateau ranges from 15 to 34 inches.

The Blackland Prairie extends from the Red River south to San Antonio, bordered on the west by the Edwards Plateau and the Cross Timbers, and on the east by the Post Oak Savannah. Annual rainfall averages 30 to 40 inches, with higher averages to the east. This region is dominated by prairie species. The most common grass species include little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastrum nutans) in the uplands and switchgrass (Panicum virgatum) in the riparian areas and drainages. Common herbaceous flowering plants include salvias, penstemons, and silphiums. This area has suffered greatly from overgrazing and agricultural use. Few intact areas remain, though many of the plants can be found along county roadsides throughout the region.

Our fall Symposium host chapter, the Tonkawa Chapter, includes both of these ecoregions.
