Areas within The Wetland

Diagram of the Wetland     Wetland Description    Plant zonation in wetlands


The Wetland area is typical of wetlands in general, in that there is a transition from open water, through swamp and marsh zones to dry land. This is called a hydrosere. These four areas, or zones, each differ substantially from the others. The differences between them are largely due to variations in the amount of standing water in  particular areas.

The regions detailed below have been separated on the basis of the plant communities occurring there. Each region in the wetland is described with the aid of pictures and plant species lists. Click on the links below to go to pages dedicated to each specific area.
