Texas coastal wetlands: Status and trends, mid-1950's to early 1990's
This report was prepared by the U.S. Fish and Wildlife Service to analyze the status and trends of coastal Texas wetlands. Comparison data was collected on a 12.8 million-acre study area using aerial photographs from the mid-1950's and early 1990's. These were analyzed to detect changes in wetlands, deepwater habitats, and uplands acreage. Although the areas of wetland concentration did not change significantly, calculations determined an average annual net wetlands loss. Most of this loss was due to upland agriculture and other upland uses such as forestry and construction. Overall, deepwater habitats increased in acreage, resulting from submergence and erosion of tidal marshes and bay shorelines. Detailed area classifications and habitat descriptions are included.
