Wetlands provide critical open space and allow for some of our most popular recreational activities, such as hunting, canoeing and fishing. Wetlands also perform many important environmental services, including storing flood waters, filtering pollutants, and supporting biodiversity. NEIWPCC works with our member states and other organizations to help study and preserve these vital areas.

Technical Soil Guides

The “Field Indicators for Identifying Hydric Soils in New England,” (Version 4, June 2020, with revisions from National Indicators 8.2) serves as a one-stop guide for identifying hydric soils in New England. The document contains hydric soil indicators specific to New England, which can be found under Problem Soils. Also included are additional guides, charts, diagrams and detailed user notes to better interpret and understand the indicators. Additional information is available from the New England Hydric Soil Technical Committee (NEHSTC).

This manual contains all applicable national indicators, plus those found in the region not addressed by the Regional Supplement to the Corps of Engineers Wetland 5 Delineation Manual: Northcentral and Northeast Region Version 2.0 (2012) or Field Indicators of Hydric Soils in the United States Version 8.0 (2016), included below.

Find the memorandum of record from the U.S. Army Corps of Engineers on the use of this manual version for Chapter 5 situations (difficult wetland situation in the Northcentral and Northeast region) here: Memo of Record Soils v4.

Problem Soils Maps

The New England Hydric Soils Technical Committee produced maps that predict where certain “problem” soils (soils with characteristics that make a hydric soil determination more difficult) are likely to be found in New England. Below are the maps and an explanatory write-up:

  1. Folists and soils with folistic epipedons
  2. Soils formed in dark parent materials
  3. Soils formed in red parent materials
  4. High-clay-content lacustrine soils
  5. Explanatory write-up
