NRCS in New Hampshire is providing leadership with the scientific verification and development of standards used to identify wetland soils. Our staff is currently involved in a long term study at the headwaters of the Mascoma River. This Comparative Field Study of Wetland Boundary Indicators is the only one of its kind in New England. It is receiving wide-spread interest because of the documentation it is providing to accurately identify and delineate wetlands as well as providing technical support for carrying out federal and state wetland regulations.

Project Design and Data Collection Methods
As the lead agency providing soil data and technical guidance on soils, it is important that NRCS meets the needs of our customers in their work with natural resources assessment and management. It was recognized that some types of landscapes in Northern New England presented challenges when it came to wetland indicators. Soils, plant communities, and hydrologic indicators were often complex and current technical documents did not provide adequate guidance. The Mascoma Project has been one way to provide the needed data to support or revise these standards.
The Purpose of the Project is to:
Better identify and describe hydric soil morphology indicative of saturation
Refine the National and Regional Field Indicators of Hydric Soils
Document defensible criteria for identifying and delineating wetland boundaries in Northern New England landscapes (frigid temperature regime).
