Water Classification

• Wetlands are areas that are covered by water or
  have waterlogged soils for long periods during
  the growing season.
• Plants growing in wetlands are capable of living
  in saturated soil conditions for at least part of
  the growing season.
• Sometimes may be unrecognizable as these areas
  will dry out.
• Wetlands are found from the tundra to the tropics
  and on every continent except Antarctica.

5
What is a wetland?

• Three Classifications
• Ground Water
• Hydrophylic Plants
• Hydric Soil

6
Groundwater Classification

• is at the surface or within the soil root zone
  during all or part of the growing season

7
Hydrophylic Plant Classification

• Plants adapted for growing in standing water or
  saturated soils, such as moss, sedges, reeds,
  cattail and horsetail, rice, mangroves, cypress,
  cranberries, etc.

8
Hydric Soil Classification

• Soils are characterized by frequent, prolonged
  saturation and low oxygen content, which lead to
  anaerobic chemical environments where reduced
  iron is present.

Importance of Wetlands Hydrologic

• Long term and short term water storage
• Wetlands protect land from damage caused by
  flooding, storms and tidal damage

11
Importance of Wetlands Water Filtration

• Wetlands remove nutrients from surface and ground
  water by filtering and by converting nutrients to
  forms that wont harm the environment

12
Importance of Wetlands Habitat

• There are a number of plant and animal species
  that can only survive in a wetland ecosystem

13
Wetland Improvements

• Wetland Restoration
• Wetland Creation
• Wetland Enhancement

14
Wetland Restoration

• A degraded wetland or former wetland is returned
  to its previous condition as much as possible

15
Wetland Creation

• A non-wetland area is converted into a wetland

16
Wetland Enhancement

• A function of the wetland is improved upon

17
Wetlands Activity

• In your groups, create a poster of the important
  facts from the wetlands sheet given to you. You
  have about 20-25 mins to complete your poster.
• When we are ready, your groups will move from
  your table clockwise and visit all the tables in
  the room. You will take notes on each poster. Be
  ready to report out. However you will not be able
  to report out on your tables wetland
  information.
