Flow alteration – from new and existing water supply projects, increased urbanization, and drought conditions – is a pervasive threat to aquatic wildlife throughout the Gulf Coast Prairie region. One species susceptible to this threat is Guadalupe Bass, an economically and ecologically important black bass species endemic to Texas. The area encompassing their range is projected to experience some of the highest population growth in Texas, placing increased demands on the aquifers and watersheds of this region. A previous GCP LCC Instream Flow project conducted by the Southeast Aquatic Resources Partnership (SARP) produced hypotheses about instream flow requirements of native aquatic species that need to be tested....
The Edwards aquifer is a karst aquifer system that is a primary water source for a large part of central Texas including the city of San Antonio, Texas. These vector geospatial data represent the geographic extent of the contributing zones for the Northern, Barton Springs, and San Antonio segments of the Edwards aquifer. The contributing zone is defined as the drainage area of the Edwards Plateau that contributes surface water to the Edwards aquifer recharge zone. The recharge zone is where surface water and precipitation infiltrate into the outcrop of the rocks that compose the aquifer (see Ashworth and Hopkins, 1995, and George and others, 2011). References Ashworth, J.B., and Hopkins, Janie, 1995, Aquifers of...
This layer idenitifies priority watersheds for the Texas Parks and Wildlife Department in the Edwards Plateau. For more informaton, contact Tim Birdsong.
Texas ecological systems data (Texas Parks and Wildlife Department [TPWD], Missouri Resource Assessment Partnership [MoRAP], and Texas Natural Resource Information Systen [TNRIS]) were used to identify map areas probable for occurrence of rare plants.

This following interest areas were overlaid to create this layer: (1) Black-capped vireo (U.S. Fish and Wildlife Service [USFWS]); (2) Edwards Aquifer zones (Edwards Aquifer Authority); (3) Golden-cheeked warbler (USFWS); (4) Northern bobwhite quail (Oaks and Prairie Joint Venture); (5) The Nature Consevancy terrestrial conservation blueprint; (6) The Nature Conservancy freshwater blueprint; (7) Texas Land Conservancy priority watersheds; (8) Texas Parks and Wildlife Department priority watersheds; (9) priority caves/karst features (Bat Conservation International). Presence/absence rasters were generated for individual layers with a cell size of 10 meters. Shared interest areas were determined by summing presence/absence...
