Plant Collection Policy

The Native Plant Society of Texas, in keeping with its basic purpose of education, conservation, and preservation of the native plants of Texas, has created this policy for its members on collection of plant material in accordance with the laws (city, county, state and Federal) and accepted practices of said activity.

Plant Rescue Guidelines

Plant rescues are special types of collection activities that Native Plant Society of Texas chapters may organize when construction activities will destroy plants. We carry outplant rescues in an attempt to save and conserve local-ecotype plants and seeds. These guidelines serve as a model for ethical and responsible decision-making and best practices for plant rescues.

Invasive Plants: Definition and Position Statement

Invasive plants are heavily contributing to the decline of our natural biodiversity and impacting the health of ecosystems by displacing native plants. In order to preserve the biodiversity and conserve natural habitat quality throughout our state, the Native Plant Society of Texas encourages the use of native plants on public and private lands and discourages the use of invasive plants. Invasive species impact nature’s balance on which all species, including humans, depend.

Position Statement on Invasive Plants

Pesticide and Herbicide: Position Statement

Guidelines for control of invasive botanical species including non-chemical and chemical methods. The Society does NOT endorse in any way the use of chemical pesticides or herbicides in private or public landscapes except under limited circumstances where other means are not effective, and the benefits significantly outweigh the risks. Each site and situation is unique, and consideration should be given to all environmental and safety factors before determining a solution.

Equity, Diversity, Inclusion Statement

As a community-based environmental conservation organization, NPSOT honors and celebrates the equally remarkable diversity of our communities and our unique ecoregion.

COVID Policy for Events and Volunteering

Chapters must follow current CDC guidelines or set their own stricter policies for meetings, demo garden work, plant sales, field trips or any NPSOT activity.

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.
