Survey of Potential National Natural Landmarks, Biotic Themes, of the Mississippi River Alluvial Plain

摘要

This study is one of a series of 61 which cover the natural regions of the United States, defined largely by Fenneman (1928). Each study describes the ecological and/or geological features characteristic of that region, then evaluates sites representative of the various features. Sites which are outstanding examples are proposed as potential National Natural Landmarks. This study reports on the ecological sites in the Mississippi River Alluvial Plain section of the Gulf Coastal Plain Natural Region. The geologic setting, landforms, climate, soils, vegetation, landuse and fauna of the natural region is briefly described, and finally 31 ecological communities are also described.
