Wetlands

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.

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
