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

Fall Symposium 2025 Logo - Teach for the Future

Salado, the location of our Fall 2025 Symposium, lies at the intersection of two ecoregions: the Edwards Plateau (Limestone Cut Plain) and Blackland Prairie (Northern Blackland Prairie).

The Edwards Plateau area is also called the Hill Country; however, this general term covers a much larger area extending farther north. Spring-fed creeks are found throughout the region; deep limestone canyons, rivers, and lakes (reservoirs) are common. Ashe juniper is perhaps the most common woody species found throughout the region. Additional woody species include various species of oak, with live oak (Quercus fusiformis) being the most common. Sycamores (Platanus occidentalis) and bald cypress (Taxodium distichum) border waterways. This area is well known for its spring wildflower displays, though they may be viewed in spring, late summer, and fall, as well. According to Texas Parks and Wildlife, average annual rainfall in the Edwards Plateau ranges from 15 to 34 inches.

The Blackland Prairie extends from the Red River south to San Antonio, bordered on the west by the Edwards Plateau and the Cross Timbers, and on the east by the Post Oak Savannah. Annual rainfall averages 30 to 40 inches, with higher averages to the east. This region is dominated by prairie species. The most common grass species include little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastrum nutans) in the uplands and switchgrass (Panicum virgatum) in the riparian areas and drainages. Common herbaceous flowering plants include salvias, penstemons, and silphiums. This area has suffered greatly from overgrazing and agricultural use. Few intact areas remain, though many of the plants can be found along county roadsides throughout the region.

Our fall Symposium host chapter, the Tonkawa Chapter, includes both of these ecoregions.
