The Appalachian Trail (AT), a 14-state footpath from Maine to Georgia, is a unit of the National Park Service that is cooperatively managed and maintained by the National Park Service (NPS), the Appalachian Trail Conservancy, AT Club volunteers, the USDA Forest Service, and other public land-management agencies. Upper elevation and ridge-top ecosystems, which comprise much of the trail corridor, have been impacted by and remain extremely sensitive to acidic deposition. Ridgetop soils that are often low in calcium make the ecosystems of the AT more sensitive to acidic deposition than other ecosystems. Furthermore, upper elevations tend to receive the highest levels of deposition. In areas along the AT, such...

Data used for assessing relationships between fish assemblages and acid-base chemistry in streams of the Great Smoky Mountains National Park, 1993-2014
Fish community richness, density, and biomass for entire communities, Brook Trout, Rainbow Trout, and minnows, including site characteristics, and water chemistry (acid neutralizing capacity, pH, nitrate, sulfate, ammonia, calcium, and total aluminum) collected at least once and as many as 13 times at each of 52 stream sites during the same years that fish were inventoried, Great Smoky Mountains National Park, 1993-2014.
