What is a wetland simple definition?
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.
How does water move in a wetland?
As water from a stream channel or surface runoff enters a wetland, the water spreads out and flows through dense vegetation. The velocity of the flow is reduced, allowing suspended material in the water to settle to the wetland surface. The roots of wetland plants can then bind the accumulated sediments.
How can you tell if a land is a wetland?
A wetland is a land area that is either permanently or seasonally saturated with water, typically having characteristics of a distinct ecosystem. Some examples include swamps, marshes, and bogs. These bodies of water can contain either fresh, brackish or salt water.
