As part of its mission to save the Attwater’s Prairie-Chicken from extinction, the Attwater Prairie Chicken National Wildlife Refuge (APCNWR) protects over 9,000 contiguous acres of Upper Coastal Prairie, second only to the core area of the Coastal Prairie Conservancy. Some of the best-quality prairie is accessible daily to the public, with 2.3 miles of hiking trails and a 3.4-mile auto loop, all within 2 hours of the Houston metropolitan region and about 20 minutes from the Sealy exit on I-10. APCNWR possesses a distinctive native flora adapted to dry, sandy soils, plus a variety of wetland species. A recently updated phenological plant list, based on iNaturalist observations and herbarium records, shows nearly 400 verified (research grade or herbarium) species of native forbs and vines and around 100 species of native grasses, sedges, and rushes. This presentation will feature about 40 species of native wildflowers characteristic of APCNWR, all seen within the last 5 years in the publicly accessible portion of the refuge.

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.
