Offwell Wetland Survey

Area A - Landward Zone

wpe44.jpg (221012 bytes)

The marsh zone grades into the 'dry' land area in the northern region of the wetland. While it can be termed dry land in comparison to the rest of the wetland, it may still flood occasionally in very wet periods and it supports plants which prefer moist conditions. This area represents the final stage in the succession from open water to dry land.          Plant zonation in wetlands       

The region supports tall trees (15 metres in height) such as Scots Pine, Alder, Willow, Oak, Holly and Silver Birch. There is also a region where Rhododendron dominates, shading out most other vegetation. The Rhododendron merges into the marsh community in the wetland.

These species lists are not exhaustive. They 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.
