OP-11: Biodiversity

The University of Houston Coastal Center contains 300 acres of coastal tallgrass prairie. This habitat is highly endangered, with less than one tenth of one percent remaining. The UHCC prairie has a high plant diversity and so is considered more valuable than other prairie properties in Texas that may be larger but do not have high plant diversity.

The land for the Coastal Center was originally a United States Army base known as Camp Wallace, which housed some 16,000 soldiers. During this time extensive land use jeopardized the original coastal ecology and by the time the university acquired the land in 1960, significant disturbance had occurred; including the introduction of invasive species. While the land was intended to serve as the site for a new campus, in 1970 the site was re-purposed to serve as an environmental field education site. It was at this point that Dr. Richard Aumann was assigned directorship of the property. With funding from over 20 federal and state agencies, and Dr. Aumann's focus on the study of invasive species, resulting publications, studies, and facility installments at the center have produced voluminous data on the biodiversity and endangered nature of the coastal prairie ecosystem. These types of studies are ongoing and now under the direction of Dr. Steve Pennings and his postdoc Dr. Chelse Prather. A brief list of present assessments include: the impact of the Deep Water Horizon Spill on coastal biodiversity as seen through terrestrial arthropods, the impact of encroaching Chinese Tallow groves on biodiversity, and the consequences of mangrove invasion into salt marsh habitats on the Texas coast. For a thorough discussion of the methodologies involved, please visit the link below to view the published articles from the coastal center.

The Coastal Center itself is an identified environmentally sensitive area known as a "coastal tallgrass prairie" with less than one tenth of one percent of the original habitat remaining according to the United States Geological Survey Research Program. While much of the native animal life may not be directly threatened, studies of biodiversity and resiliency of their food webs directly gauge the ecological health of this threatened ecosystem. For example populations of Prokelisia sp. planthopper, Chaetopsis sp. fly, and Conocephalus aigialus, are not threatened, but the substrate (coastal grasses) supporting their food webs is. Thus, by generating assessments of these arthropods food webs, the Coastal Center is able to gauge the impact of various detrimental ecological events. Again, links to publications of these studies are available below.

So long as the Coastal Center continues operations the resulting studies and environmental stewardship of this highly threatened area will continue. Perhaps one of the most long term programs to positively affect the coastal prairie habitat is the continual stocking and redistributing of seeds from threatened plant species in the center. These seeds are stored for coastal center use in replanting or distributed to both private and public entities for their use in further restorative efforts of coastal prairie across the country.
