The Southern Appalachian Assessment Man and the Biosphere Program (http://samab.org), a partnership among three Federal agencies and several states, conducted a comprehensive ecological studies in 1996. Results were published as a series of shape files, one of the first programs to do this. Critically for us, SAMAB attempted to map streams that support wild trout across the entire southern Appalachians (Virginia through Georgia).
While these data may have been somewhat superseded by the EBTJV data (which was produced by the same GIS team that did this work), these data are still the only stream level data I’ve found which show the extent of wild trout in the South. Since it looks like the SAMAB website hasn’t been updated at all since 2006, we thought it useful to put a library of the datasets (which are shape files) here, just in case they were to disappear from the few repositories they now exist on the web. These are public data, if you publish something using it (such as the many maps we created on this site) you should reference the Source:
Herman, K.A. (ed.) 1996. The Southern Appalachian Assessment GIS Data Base CD ROM Set. Southern Appalachian Man and the Biosphere Program. Norris, TN.
