Wetlands come in many different shapes, sizes, and types. They vary in the amount
of water they hold, how long they hold water, and the type of vegetation they support. Not all wetlands have standing
water during the growing season.
All wetlands must meet three criteria:
1. soils developed in wet conditions 2. wet either above ground or wet
within 12 inches of the surface during all or part of the growing season 3. plants
adapted to live in wet soil conditions
U.S. Fish and Wildlife Service divided wetlands into 8 types (Types 1-8). The two primary characteristics used in the
classification system include the wetland's dominant plant type and water depth during the growing season.
Wetlands monitored in WHEP are depressional wetlands with emergent marsh vegetation (Types 3, 4, or 5).
The Minnesota Pollution Control Agency designed and tested
the WHEP sampling protocols for Type 3, 4 and 5 wetlands located in the Central Hardwood Region of the State of Minnesota.
Wetlands sampled in WHEP are chosen by the sponsoring agency
(City, Watershed Managment Organization, Park Board etc.).
