Fall Symposium: Conserving Native Plants of the Texas Coastal Prairies

The 2019 annual symposium will focus on conserving native plants in the upper Texas coastal prairies, also known as the Northern Humid Gulf Coastal Prairies in the EPA Level IV ecoregion map.

Quaternary-age deltaic sands, silts, and clays underlie much of this gently sloping coastal plain. The original vegetation was mostly grasslands with a few clusters of oaks, known as oak mottes or maritime woodlands. Little bluestem, yellow Indiangrass, brownseed paspalum, gulf muhly, and switchgrass were the dominant grassland species, with some similarities to the grasslands of the Blackland Prairies. Almost all of the coastal prairies have been converted to cropland, rangeland, pasture, or urban land uses. The exotic Chinese tallow tree and Chinese privet have invaded large areas in this region. Some loblolly pine occurs in the northern part of the region in the transition to the South Central Plains. Soils are mostly fine-textured: clay, clay loam, or sandy clay loam. Within the region, there are some differences from the higher Lissie Formation to the lower Beaumont Formation, both of Pleistocene age. The Lissie Formation has lighter colored soils, mostly Alfisols with sandy clay loam surface texture, while darker, clayey soils associated with Vertisols are more typical of the Beaumont Formation. Annual precipitation varies from 37 inches in the southwest portion to 58 inches in the northeast, with a summer maximum.

The symposium headquarters will be in League City, between Houston and Galveston. at the South Shore Harbour Resort and Conference Center, which is on the south side of Clear Lake across the lake from the Johnson Space Center. The event begins with a reception on Thursday evening for those arriving early, speakers on Friday morning with a choice of field trips in the afternoon, more speakers and breakout sessions on Saturday, and an awards banquet on Saturday night. A social event is planned for Friday night on the Kemah Boardwalk. In addition they have prepared a list of suggested side stops and field trips for those traveling on Thursday and Sunday.

Registration prices vary depending on your level of participation.
