2014 Annual Report on Performance of Iowa CREP Wetlands: Monitoring and Evaluation of Wetland Performance, January 1, 2014 – December 31, 2014

A unique aspect of the Iowa CREP is that nitrate reduction will not simply be assumed based on wetland acres enrolled, but will be calculated based on the measured performance of CREP wetlands. As an integral part of the Iowa CREP, a representative subset of wetlands will be monitored and mass balance analyses will be performed to document nitrate reduction. This will allow further refinement of modeling and analysis tools used to site and design CREP wetlands
