1. Texas Ecological Regions

Texas is a large land area covering approximately 261,914 square miles (if you include water area, there are 267,277 square miles). The state is located at a geographic crossroads where many of the major regions of the United States come together: the coastal prairies, the Mexican sub-tropics, the southeastern pinewoods, the central hardwoods, the Great Plains, and the southwestern desert. This accounts for the tremendous climatic and geographic diversity of the state. Texas has 10 climatic regions, 14 soil regions, and 11 distinct ecological regions. These ecological regions of the state represent differences in soils, topography, geology, rainfall, and plant and animal communities.* There are, however, several other ways of classifying the natural environment, such as by river basin, hydrologic sub-basins, or vegetation systems.

Each of these 11 ecological regions has unique wildlife and fish habitat and most of those habitats are being threatened. Among the top causes of the loss of habitat is agricultural development; urban development or other forms of human encroachment, such as dam construction; and invasive species.
