March 2021 Meeting – Ricky Linex with “Riparian Management, Why Creeks Act the Way they Do”

**ARCHIVED POST **

Join us on Zoom for our March meeting on the 15th at 6:30 for social time, 7:00 for quick announcements, then our program.  This month we’ll have Ricky Linex with “Riparian Management, Why Creeks Act the Way they Do”.  Register in order to get the meeting link via https://us02web.zoom.us/meeting/register/tZUqd–gpj8tGNVk0S_M7JgVyQ3dErFHDFJk

This presentation goes into the relationships of riparian areas to the uplands that provide water to the riparian areas and the importance of good land stewardship for the maintenance of healthy creeks and rivers.  I will show several native riparian plants and discuss a strength rating of each plant as well as its wetland indicator rating which shows how much wetness a plant can tolerate.  We will discuss what goes wrong when vegetation and landform cannot support the excessive amounts of water provided to the creeks, say from overgrazing or urban growth, and how erosion results.  We will show how creeks can be restored by removing the hindrances that created the problem.  This will take a full hour to give and I will provide a handout that list riparian plants of north central Texas including their strength rating and wetland indicator rating.

Ricky Linex was a wildlife biologist for the Natural Resources Conservation Service in Weatherford until his retirement in January.  He is the author of “Range Plants of North Central Texas, A Land User’s Guide to Their Identification, Value and Management” – a plant identification book for Texas detailing regional grasses, forbs, and woody plants – which was honored as an “Outstanding Publication” by the Texas Chapter of The Wildlife Society.  He is also a past president of our Cross Timbers Chapter in Weatherford and is a past member of our State Board.  He has made the study of plants his passion for the past 37 years. A genuine land steward who combines his knowledge of the land with an appreciation and respect for the land.

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.
