We are the Clausentum Fen Conservation Group. Join our mission to protect the biodiversity and the enjoyment of this beautiful area.

Clausentum Fen

The Fen lies alongside the river Itchen and has chalk stream, fen and woodland habitats, but it is drying out. Tree and scrub growth have choked the fen causing great deterioration in water flow and light and led to a reduction in biodiversity. We hope to reverse this.

What's Happening....

We have been scything some of the grassy areas to suppress coarse grasses and create habitat for wild flowers.


We have been scything most of the grassy strip on zone 3 in front of the pools, leaving some areas which have interesting plants. Some of the marginal vegetation has been cleared in places which gives a better view of the water and creates new open areas. The low part of the island nearest the road has been scythed but the other island has been left. Some other areas around the pools will also be scythed to provide a variety of habitats. Himalayan balsam clearance has also been taking place. There have been far fewer plants of this than last year so we hope that the Fen has been pretty much cleared of this invasive species.
