Pennsylvania Center For Environmental Education

Wetlands serve many functions. They prevent flooding, filter and clean water supplies, and provide critical habitat for wildlife.

Despite the benefits of wetlands, over half of all wetland habitats in Pennsylvania occurring historically have been filled.

In order to limit human impacts on wetlands people need to know the characteristics of a wetland.

Which of the following are characteristics of wetlands?

any area that is inundated (flooded) or saturated for a certain number of days in a row

wet long enough during the growing season that anoxic (without oxygen) conditions are created

area where hydrophytes (water-loving plants) will grow

all of the above
