2: Marshes | Marshes are a type of wetland where the vegitation is dominated by tall grass-like plants. Typically plants of North American marshes include cattails, bulrushes, and saw-grass.

3: Saw-Grass | Cattails | Bulrush

4: Swamps are forested or shrub dominated wetlands, usually associated with lowlying, periodically or permanently flooded areas around streams and rivers. | Swamps provide habitat for numerous species of animals, many of which have specific requirements for this type of habitat.

5: Shallow Wetlands Shallow Wetlands are known locally as ponds, sloughs, or potholes. These are small bodies of surface water. | Wetland Ecology Wetlands are dynamic ecosystems, most wetlands over time are filled up with sediment and other materials. | Losses of Wetlands All wetlands have great instinic value as natural ecosystems, and they all support species of plants and animals that occur nowhere else

6: Fen | Fens, are peat-forming wetlands that receive nutrients from surrounding mineral soils and from groundwater movment, fans differ from bogs because they are less acidic and have higher nutrient levels. They are therefore able to support a much more diverse plant and animal community.

7: Vocabulary | Alkalinity- The amount of Alkali in a solution. In fresh water, alkalinity is mainly associated with bicarbonates, carbonates, and hydroxides, and it is generally measured by titration with acid to a fixed end point. Anaerobic- Enviroments in which oxygen is not present, or only present in a very small concentration. Hydrology- The study of the distribution, movement, and physical-chemical properties are regarded as a type of ecological degradation.

8: Euthrophication- An aquatic ecosystem process by which increased productivity results from an increase in the rate of nutrient input. Excessive eutrophication and its symptons are regarded as a type of ecological degradation. Minerotrophic- This refers to wetlands that receive much of their nutrient supply as substances dissolved in water draining from a part of the watershed that is higher in altitude. | Vocabulary

9: Vocabulary Ombrotrophic- This refers to wetlands with no input of nutrients from ground water or surface water, so that all of the nutrient supply arrives from the atmosphere with precipitation and dust. Watershed- The expense of terrain from which water flows into a wetland, waterbody, or stream.
