What is a Wetland
• Wetlands provide important homes for plants and
animals, including over 50 percent of threatened or
endangered species.
•
Improving water quality by filtering out trash and toxics
•
Capturing and storing greenhouse gasses from earth’s
atmosphere
•
Serving as buffers against storms, flooding, and erosion
control
•
Wetlands are the transition area between open water and
dry land, constantly appearing and disappearing with the
ebb and flow of tides.

Benefits Of Having
Wetlands
• Wetlands are important to the ecosystem
because of the birds, animals, and plants
that thrive there.
• The abundant vegetation provides a
habitat and food for wildlife and breeding
grounds for a large number of birds.
• Wetlands protect the dry land from erosion
and rivers and lakes from drought. They
store water, slow the rising waters of a
flood and prevent rapid runoff that would
otherwise cause erosion.
Why We Should Save
Wetlands
• Wetlands are an important part of our
national heritage.
• Our economic well-being and quality of life
largely depend on our nation's wealth of
natural resources, and wetlands are the
vital link between our land and water
resources.
• As wetlands are lost, the remaining
wetlands become even more valuable. We
have already lost many of our nation's
wetlands since America was first settled.
