Invasives conference set for February 26-28

**ARCHIVED POST **

The fifth statewide conference on invasive species aims to raise public awareness of the problems posed by invasive species in the state of Texas.

The Texas Invasive Plant & Pest Conference will be February 26-28 at the University of Texas Marine Science Institute in Port Aransas.

TIPPC_LogoAs invasive species spread and take over ecosystems, they decrease biodiversity by threatening the survival of native plants and animals. In addition, invasive species are also costly. It is very expensive to prevent, monitor and control the spread of invasives, not to mention the damage to crops, fisheries, forests, and other resources. Invasives cost the US $137 billion annually.

Hosted by the Texas Invasive Plant & Pest Council, the Marine Science Institute and the Institute for the Study of Invasive Species the conference will be a professional level meeting including keynotes, concurrent sessions, posters, field trips and symposia. This conference is designed to serve scientists, land managers, state and federal agencies, local governments, the green industry and others interested in invasive species issues in the state of Texas.

Conference goals include fostering  collaboration among the diverse interests that share in the common goal of protecting Texas from the threat of invasive species; facilitating communication; and providing a venue for sharing information about prevention, early detection, control & management, information management, and research.

The Native Plant Society of Texas will be one of the sponsors of the conference which is open to all who have an interest in controlling invasive species.

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.
