Conservation Tips: Controlling Invasives, How to Know Your Soil Type

View this presentation on  Fredericksburg Texas Native Gardening  

Jonathan Watt, President, Fredericksburg Chapter of NPSOT, recently announced the September 23 guest speaker in the September issue of the Native News.

Warren Day, the USDA District Conservationist in Fredericksburg will highlight the conservation services that support our goals in restoring native plants. He has been part of the U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS), throughout west Texas for 15 years, serving in Gillespie Country for the last 7 years.

“We’re working hard at NCRS to educate the public on how to be part of the conservation solution ,” said Day. “I’m looking forward to sharing tips on how homeowners and landowners can control invasive species and use our soil information to keep our water clean and abundant, our soils healthy, and have resilient landscapes and thriving agricultural communities.”

“Mr. Day will share potential control methods for a variety of invasive non-native plants and demostrate how to use the NRCS’ Web Soil Survey to map soils and obtain data that is useful to home and landowners.” Watt said, “We can all do our part to voluntarily conserve our resources, and he’ll share some great tips about how to do that.”

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.
