NPSOT 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.

Collection of any plant material from public land, such as parks, forests, and roadsides, without proper consent from the proper authorities could be considered vandalism (picking roadside flowers itself is not illegal). To collect any part of an endangered species on public land requires the collector to secure a permit, allowing such activity, from the proper authorities. Texas Parks and Wildlife has two classifications of permit, one for education/research facilities and the other for commercial/private personnel, for land under its jurisdiction.

Collection of plant material from privately owned land (this includes land owned by timber companies and other industries) is only allowed when the collector has received prior written permission from the owner. Endangered species may not be collected without the permission of the land owner.

When dealing with rare, endangered, threatened, uncommon, or species in an unusual location, several factors should be taken into consideration.

First, propagules (seed, cuttings, divisions) should be collected, rather than the whole specimen, whenever possible. Take no more than a small proportion from any site.

Second, if the population at a given site contains less than one hundred specimens, it should be left undisturbed if possible. (This factor should include more common species due to the importance of genetic diversity.)

Third, material should only be collected when there is a high probability of success with propagation/relocation. (Example: Lady Slipper Orchids should never be disturbed because they don’t transplant, and propagation of seed is difficult).

Fourth, relocation/removal of a complete specimen should only be done when the site or species is in imminent danger of being disturbed or destroyed.

Fifth, material in preserves, wilderness areas, and other protected lands (like Big Bend National Park) should never be utilized.

Use common sense.

This policy on plant collection has been developed and adopted by the Board of the Native Plant Society of Texas, in response to many requests from our chapters. Our thanks to Peter Loos for his research on legal and ethical issues, and for drafting the final document.

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.
