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. It is a Site of Importance for Nature Conservation but has little active management. The group was founded in 2017 local volunteers, to study the site and help to manage it for biodiversity.

What's Happening....

We are working with some of the community service volunteers from Winchester college to help clear some of the vigorous aquatic grasses in zone 3.


HCC is planning to undertake some practical conservation work in zone 1 this winter to enhance the habitat, mainly by removing some of the tall evergrren Thuya that are not native and cast a deep, dry shade. Further details are available in a flyer here.
