Faggots on the restored Fowlmere

Project summary

Edit project overview to modify the project summary.

The river had been heavily dredged in the past, resulting in a distinct lack of gravel within the river, and the channel was over-deep and filled with silt. Long profile surveys also indicated that the natural profile of the river had been significantly altered. Habitat restoration work progressed in three phases:

- Riffle creation in March 2006 (~30m) - Marginal habitat enhancement in 2007 (~150m) - Bed raising combined with channel narrowing in 2009 (~250m)
