2011 Annual Report

1a.Objectives (from AD-416)
Provide science-based data, results and information to routinely inform conservation decisions affecting wetland ecosystems and the services they provide. Develop a broad collaborative foundation that facilitates the production and delivery of scientific data, results and information.

1b.Approach (from AD-416)
Conduct collaborative regional investigations to: - quantify wetland ecosystem services across an alteration gradient in agricultural landscapes; - interpret effects of conservation practices and programs, and the effectiveness (i.e., the type, location, land treatment, design and/or management) of conservation practices on ecosystem services; and - identify multiple-scale factors that influence the capacity for a wetland to provide an ecosystem service within a range of estimates.

3.Progress Report

In 2010, efforts focused on.
1)calibration of a Hydrologic Landscape Region (HLR) model that delineates moisture variables in agricultural and wetland landscapes, and.
2)uses that information to define nitrogen removal in those systems. In 2011, the working HLR model was further refined and calibrated, and further work was done to delineate the details of groundwater movement and nitrogen mineralization at selected wetlands sites. This work was recently reported on in a special symposium talk on the Mid-Atlantic CEAP Project.
