Wetlands are areas where the land is covered by shallow water or the soil is saturated to near the surface for at least two weeks during the growing season. Some common names for different types of wetlands are swamp, marsh, and bog.

What is a Wetland?

Wetlands are defined based on their hydrology, soils, and plants. The U.S. EPA defines wetlands as “those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas.”

Why Should We Value Wetlands?

Wetlands improve water quality, protect against floods and droughts, provide important wildlife habitat, and contribute to the resilience and biodiversity of West Virginia’s natural environment.

How Wetlands Work

Wetlands are an efficient and cost effective way to remove excess nutrients in our waterways and improve water quality.

Flooding and Sediment Reduction

Wetlands help to decrease the damage caused by flood events and can filter sediment pollution out of water.

Wetlands & Water Quality

Learn how wetlands remove pollutants from the water supply.

Components of a Wetland


Wetland plants are specially adapted to live in wet, low-oxygen environments. From magnificent pin oak swamps to colorful meadows of swamp milkweed and sedges, wetlands are some of the most productive ecosystems in the world - comparable to rain forests and coral reefs.

Learn More About Wetland Flora


Wetlands can be thought of as "biological supermarkets." They provide large volumes of food that attract wildlife, and are a great place to view birds, butterflies, dragonflies, frogs, salamanders and small mammals.

Learn More About Wetland Fauna


Wetlands occur all over West Virginia, from boggy headwaters on the tops of our mountains to the low floodplains of the Potomac and Ohio Rivers. Wetland soils reflect the particular hydrology of each wetland type.
