Wetland Monitoring and Assessment Documents and Data

Plan Implementation and Program Development

With grant support from the Environmental Protection Agency (EPA) ( the Department has continued to work with the New England Interstate Water Pollution Control Commission (NEIWPCC) and with the Rhode Island Natural History Survey (RINHS) to implement the Rhode Island Freshwater Wetland Monitoring and Assessment Plan (2006) in accordance with the proposed five-year timeline. Under the Clean Water Act, states are required to report on the condition of all waters of the United States, including wetlands. The initial work has focused largely on developing a Rhode Island specific rapid assessment method (RAM) building on work that has been completed in other states. Development and application of a RAM will facilitate watershed-based conditional reporting and will support objectives identified in the Plan.

Documents and data are listed by field season below:

Year 1 (2006) - Woonasquatucket River Watershed

Year 2 (2007) - Upper Pawcatuck River Watershed Year 3 (2008) - Subbasins of Pawtuxet and Hunt River Watersheds Year 4 (2009) - Atlantic White Cedar Swamps, Bogs, and Fens Statewide Year 5 (2010) - Integrating Rapid Assessment with Landscape and Biological Indicators Statewide Year 6 (2011) - Developing Floristic Quality Assessment and Demonstration Wetland Mapping

A reliable wetlands dataset in an essential component of a comprehensive wetland monitoring and assessment program. In their report "Options for Mapping Rhode Island's Wetlands" (2001), the authors identified the limitations of existing statewide wetland map coverages. While the DEM Office of Water Resources supports creation of a new wetlands dataset, the cost involved, using large scale color infrared images, remains a constraint.

The U.S. Fish and Wildlife Service (USFWS) completed revisions and updates to the National Wetland Inventory maps for Rhode Island (2009). These maps are available digitally at
