    Technical Guides
    Field Indicators for Identifying Hydric Soils in New England

    Version 3 of this guide is now available and helps field wetlands resource personnel identify and document hydric soils and their boundaries. These field indicators provide consistent and reliable evidence as to whether a certain soil meets the definition of a hydric soil. When properly applied, this field guide yields results that are consistent with the identification of hydric soils as per the 1987 Army Corps of Engineers Wetlands Delineation Manual. Field Indicators for Identifying Hydric Soils in New England is written by the New England Hydric Soils Technical Committee and published by NEIWPCC. It is updated periodically to reflect new information and refine the indicators. Version 3 (April 2004) supercedes Version 2, published in 1998. A separate supplement providing background information on making a hydric soil determination is included with Version 3.

    Problem Soils Maps
    The NEHSTC has 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. The maps are available in PDF form below, along with 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
