Big Bend Chapter

Sierra Club Program – Sierra Club Explores Water Resources, October 23

**ARCHIVED POST **

[from Dallas Baxter]

The Big Bend group of the Sierra Club will meet from 7:15 to 9 p.m. Wednesday, October 23 at the Alpine Public Library to explore water resources in the Tri-counties.

Water, or the lack of it, impacts every part of the area. Growth as well as threats are coming into the Texas Big Bend. The program will offer information about them and about how to meet them.

“We need to understand our water resources in order for us to take steps to better protect the resources we have now and in the future,” said J.D. Newsom, executive director of the Big Bend Conservation alliance and one of the presenters. “Water conservation can play a part but, more importantly, better planning and policy will be necessary,” he said.

Also presenting is Dr. Kevin Urbanczyk, Sul Ross professor, who will give participants a good base understanding of area water resources and current modeling. He will also talk about the region’s desired future conditions. With that understanding strategies can be developed to better protect area water resources.

The community is encouraged to take this opportunity to learn more about this important challenge. Sierra Club membership information will be available at the meeting.

The Alpine Public Library is located on 13th St., between Sul Ross Avenue and Avenue E in Alpine.

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.
