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 Speaker

Charles Winker is a retired geologist residing on the Fayette Prairie near Brenham with his wife Susie and their blue heeler Elsa. A Chicago native, he has lived in Texas for 43 years, plus five years each in Georgia and Arizona. Upon retirement in 2016 he became interested in prairie conservation and field botany, joined Texas Master Naturalists and the Native Prairie Association of Texas, embraced iNaturalist, and began volunteering at the Coastal Prairie Conservancy, Winedale Historical Complex, and APCNWR. He is particularly interested in native Texas grasses, which he cultivates on their property.

About the Region

2026 Fall Symposium Logo

This low-elevations region of Texas extends inland from the barrier islands, about 60 or so miles, and stretches from Brownsville to Louisiana. In total, it covers about 9.5 million acres, with a high point of 150 feet in elevation. More than 1000 species of plants can be found in this region. On the southern end, species more common in Mexico (such as Sabal mexicana) and Central America occur.

The barrier islands provide us with dune systems, and clay flats to the inland side, which have species found in these areas alone. Many plants here, such as Ipomoea pes-caprae (beach morning glory), can be found throughout tropical regions of the globe. I’ve encountered the same species on the beaches of Guam.

Once inland, vast marshes and wet prairies occur. Occasionally, oak (Quercus fusiformis) groves can be found. Common grasses include species of Bothriochloa, Paspalum, and Sporobolus; eastern gamagrass (Tripsacum dactyloides); and switchgrass (Panicum species). Many rivers and creeks cut through the Gulf Prairies, and along these riparian areas various species of trees, Sabal minor, and other plants adapted to clay soils can be found. Due to overgrazing, farming, and fire suppression, woody species such as mesquite (Prosopis glandulosa) and huisache (Acacia farnesiana), and invasive species such as chinaberry (Melia azedarach), Brazilian pepper (Schinus terebinthifolius), and Chinese tallow (Sapium sebiferum) have increased and displaced our native flora.
