Ecorestoration of riparian forests for nonpoint source pollution control: Policy and ecological considerations in Illinois agroecosystem watersheds

The Central Corn Belt Plains Ecoregion of Central and Northern Illinois has a significant nonpoint source water quality problem that is not being successfully addressed by current agroenvironmental policy. Trend analysis showed that concentrations of nitrate, dissolved phosphorus, and total phosphorus were not reduced in thirteen watersheds between 1986 and 1992 despite implementation of the CRP program. Average stream nitrate concentration between 1977 and 1992 (7.2 mg/L) was well above levels expected for unimpacted prairie streams and frequently exceeded 10 mg/L. Regression analysis showed that average stream nitrate concentration was strongly related to land loadings of nitrogen fertilizer.
