Summary

This data product was created by The Nature Conservancy as part of the project: A Stream Classification for the Appalachian Region (Sheldon et al. 2015). The stream classification covers parts of 17 states in the Eastern US, including eight Northeast Association of Fish and Wildlife Agencies (NEAFWA) states. The project area for this analysis was extended beyond the Appalachian LCC boundary to include all of the Ohio River Basin, and to include any 8 digit Hydrologic Unit Code (HUC8) watersheds that touched the Appalachian LCC or the Appalachian LCC Marcellus Shale Analysis Project Boundary, another aquatic resource analysis funded by the Appalachian LCC. The objectives of the stream classification were to: create a mapped classification [...]

Purpose

We developed a hierarchical classification system and map for stream and river systems in the Appalachian Landscape Conservation Cooperative region encompassing parts of 17 states. The classification used six primary attributes to define stream habitats: size, gradient, alkalinity, temperature, hydrology, and confinement. These variables were identified and agreed upon by a steering committee of stream and river experts representing the states and region. All mapped stream reaches (1:100,000) were tagged with information on each variable based on extensive data compiled, or modeled, for each reach. For each variable, ecologically meaningful class breaks were identified and the variable classes were combined to yield a regional taxonomy. The complete set of types was simplified using recommended prioritization and collapsing rules as follows: headwaters and small rivers were classified based on gradient, temperature, and hydrology (e.g. high gradient, cold, flashy, headwater) and medium to great rivers were classified based on confinement, temperature, and hydrology (e.g. low gradient, warm, unconfined, large river). The simplification identified 62 stream types within the study area. The classification was clipped to the Pennsylvania state boundary to be used in an online training course for the Riparian Restoration Decision Support Tool.
