Ecological Survey Data for Environmental Considerations on the Trinity River and Tributaries, Texas.

Abstract

The general objective of the study was to provide a base of scientific data to be used in evaluating the ecological significance of future water development plans on the Trinity River. The specific objectives were: (1) to determine the degree of existing eutrophication and water pollution; (2) to study ecological factors influencing the distribution and abundance of fishes, birds, and mammals; (3) to describe and analyze representative plant communities; (4) to describe and analyze terrestrial and aquatic macroinvertebrate communities; (5) to locate geological structures of ecological and economic significance and to analyze their present and potential effects on biotic communities; and (6) to analyze certain lignite deposits for heavy metals and sulfur and analyze their potential effects on biotic communities.
