|Biology of the Edwards Aquifer|
The Edwards Aquifer and its Great Springs are home to over fifty rare and unique species of plants and animals. From songbirds and native flowers to aquatic salamander and blind cave-dwellers, we are living in the midst of enormous biological diversity. The rugged limestone terrain supports terrestrial species, like the Golden cheeked warbler and Black capped vireo, both songbirds. The karst limestone of the Edwards Aquifer provides habitat for endangered troglobites or cave dwelling species, including rare spiders and beetles. The strong-flowing springs of the Edwards Aquifer provided habitat for aquatic species, dependent on clean and abundant water for survival.
