AB Conservation buffer is a best management practice for repairing impaired streams and restoring ecosystem functions in degraded watersheds. This paper compares the cost-effectiveness of three conservation buffer placement strategies in the Raritan Basin in New Jersey. Three strategies are the fixed-width riparian buffer restoration strategy based on state and local regulatory rules, the variable-width riparian buffer restoration strategy based on a nonregulatory watershed protection initiative and the variable source area—based conservation buffer placement strategy derived from an alternative concept of watershed hydrology. The variable source area—based conservation buffer placement strategy targets the most hydrologically critical source areas in a watershed for buffer placement. A digital elevation model, land use, soil, and stream data are used to identify critical source areas for buffer placement. The results show there are only minor differences in the cost-effectiveness of the fixed- and variable-width riparian buffer restoration strategies and that variable source area-based buffer placement strategy is more cost effective than the fixed- and variable-width riparian buffer restoration strategies. The critical source areas for placing conservation buffers are useful information for local watershed management, soil and water conservation, and land use planning. © 2009 by the Soil and Water Conservation Society
