Area C - Swamp Zone
|This area is permanently covered in
standing water. It lies on the edge of the open water zone and gives way to marsh behind
it, where the standing water levels vary and the sediment is not permanently covered by
|On the southern edge of the wetland where the water
depth is 1-10 cm deep, plants such as Water Mint (at left), Yellow Iris, Greater Reedmace,
Branched Bur-reed, Willow and Common Duckweed are found in abundance. As water depth
increases, the emergent vegetation develops into pure stands of Branched Bur-reed, with
Canadian Pondweed and Various-Leaved Water-Starwort submerged beneath the water surface
and Duckweed floating on the top. Branched Bur-reed dies out where the water depth exceeds
In the western swamp region of the
wetland the composition of the vegetation is somewhat different. In the shallower regions,
Water Mint, Yellow Iris, Greater Reedmace, Branched Bur-reed and Willow are found as in
the southern swamp area, although here with the addition of Water-plantain, Greater
Spearwort and Bogbean. The deeper water areas here consist of pure stands of Bogbean.
In both regions, the substrate is composed of a deep fibrous tangled
mass of rhizomes, roots and old leaf bases. The underlying sediment is black and

represent initial collections and identifications carried out in early autumn. Many
species of flowering plants may already have flowered and died back at this time and would
therefore have been missed. These lists will be updated periodically.
