Fish and Other Aquatic Resource Trends in the United States: A Technical Document Supporting the Forest Service 2010 RPA Assessment

By Andrew J. Loftus and Loftus

The Forest and Rangeland Renewable Resources Planning Act (RPA) of 1974 requires periodic assessments of the status and trends in the Nation's renewable natural resources including fish and other aquatic species and their habitats. Data from a number of sources are used to document trends in habitat quality, populations, resource use, and patterns of imperilment among aquatic fauna. Freshwater habitat quality varied widely across the United States. Nationwide, more than half of monitored lakes were ranked in good condition, but the percentage ranged from a high of 91 percent in the upper Midwest to a low of 1 percent in the Northern Plains. Habitat conditions in monitored small streams indicated that 42 percent were found to be in poor condition. The Southern Appalachians, Southern Plains, and Northern Plains have 50 percent or more of their stream lengths in poor condition. The condition of small stream habitats was best in the Western mountains. Data availability continues to limit comprehensive evaluations of freshwater fish populations.
