Wetland Types
"Wetlands are areas where water covers the soil, or is present either at or near the
surface of the soil all year or for varying periods of time during the year, including during
the growing season. Water saturation largely determines how the soil develops and the types of
plant and animal communities living in and on the soil. Wetlands may support both aquatic and
terrestrial species. The prolonged presence of water creates conditions that favor the growth
of specially adapted plants and promote the development of characteristic wetlands soils."
