Stream habitats for this project were classified using six primary attributes: size, gradient, temperature, hydrology, buffering capacity, and confinement.
This study developed a mapped classification system for stream and river systems in the Appalachian LCC region to inform conservation planning for aquatic biodiversity. Stream habitats were classified using six primary attributes: size, gradient, temperature, hydrology, buffering capacity, and confinement. Information on each variable was based on extensive data compiled or modeled. Variable classes were then combined to yield a regional taxonomy.

A classification system and map was developed for stream and river systems in the Appalachian LCC region, encompassing parts of 17 states. The product is intended to complement state-based stream classifications by unifying them into a single consistent system that represents the region’s natural flowing aquatic habitats. The results can be used to understand ecological flow relationships and inform conservation planning for aquatic biodiversity in the region.
The entire stream classification dataset is available for download as a zip file.Included in the download, is a shapefile of all of the stream flow lines within the study area. Information about each of the features is available in the attribute table of the shapefile. An Excel file is included which describes each of the fields in the attribute table. In addition, several layer files are also included: alkalinity classes; confinement classes; gradient classes; hydrologic classes; size classes; temperature classes; and a combination of temperature, gradient, confinement, and size classes. The layer files refer to data within the shapefile, but preserve a pre-defined symbology for users to more easily visualize the...
Identifying aquatic ecosystems requires a classification of stream and lake features into recognizable categories. Although a number of nationally recognized terrestrial community classifications exist, currently there is no national or international standard for classifying aquatic communities or ecosystems. Despite the lack of a national aquatic community classification, aquatic ecosystem classifications and frameworks have been developed at a variety of spatial scales to reflect the distribution of aquatic biological communities. This report reviews these freshwater classification frameworks, providing detailed analysis and application examples of taxonomic, environmental, and hydrologic classifications in use...
The classification unifies existing geomorphic and hydrologic classifications that occur within the LCC. It represents aquatic habitat types across this region in a manner that is appropriate and useful for building ecological flow ecology relationships and other conservation planning tools.
The goal of this project is to develop a hierarchical classification for stream and river systems within the Appalachian Landscape Conservation Cooperative (LCC). This classification system will identify and consistently map ecologically similar types of rivers and streams using a flexible hierarchical set of geomorphic and hydrologic variables deemed appropriate for classification by the participating states and relevant to the spatial scale of management.
Principal investigators at The Nature Conservancy developed a hierarchical classification system and map for stream and river systems for the Appalachian LCC that represents the region’s natural flowing-water aquatic habitats.
The product is intended to complement state-based stream classifications by unifying them into a single consistent system that represents the region’s natural flowing-water aquatic habitats. The results can be used to understand ecological flow relationships and inform conservation planning for aquatic biodiversity in the region.
