Some of our most popular recreational activities, such as hunting, canoeing and fishing, occur in wetlands. Wetlands provide open space, an important but increasingly scarce environmental asset in the Northeast.

NEIWPCC works with our member states and other organizations to help study and preserve these vital areas.

Field Indicators for Identifying Hydric Soils in New England, Version 3

1 manual page/PDF page format; 91 pages, 1.6 MB
2 manual pages/PDF page format; 47 pages, 1.6 MB
Supplement; 12 pages, 0.3 MB

Written by the New England Hydric Soils Technical Committee and published by NEIWPCC, this guide helps define soul boundaries by explaining how to find consistent and reliable evidence as to whether a certain soil meets the definition of a “hydric soil,” as defined in the 1987 Army Corps of Engineers Wetlands Delineation Manual.

Please note that the artwork in these electronic versions is lower resolution than the hard copy, in order to reduce file size.

USACOE New England District Memorandum

The U.S. Army Corps of Engineers New England District has issued a Memorandum (1 MB) regarding the use of Version 3 of the field indicators guide.

Problem Soils Maps

The New England Hydric Soils Technical Committee 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
