Restoration Project

The Devil's Dyke was traditionally managed by sheep grazing. This helped to maintain the open, species-rich chalk grassland habitat that supports so many flowers and insects. However, during the 20th century grazing began to decline. This allowed scrub to start to dominate parts of the Dyke and shade out the chalk grassland.

Today, Devil's Dyke is managed in a way that aims to protect and extend the rare grassland habitat and its associated wildlife.

The five year Heritage Lottery Funded Restoration Project aims to restore the site to its former glory and ensure that the future management of the site is possible by establishing long-term management practices that are financially sustainable.

Dense scrub can damage archaeology as well as reducing areas of open grassland. So by clearing back scrub, future generations will be able to appreciate the monument and its grassland.

Where areas have been cleared of scrub, the resulting bare banks are vulnerable to erosion. So locally sourced grass seed is applied to stabilise the slopes. 'Hydro-seeding' is a technique more often used on new road verges and has proved to be a practical way of applying seed to Devil's Dyke's steep banks.

Mowing of the recently seeded banks helps to encourage the grasses and herbs and reduce the more aggressive annual species.

Grazing animals encourage the wildflowers & herbs to flourish whilst keeping young scrub and weeds at bay. Several sections of the Dyke that are owned by Cambridgeshire County Council have been entered into the Countryside Stewardship Scheme and this has allowed grazing to take place. Elsewhere on the Dyke, graziers are being encouraged by the Restoration Project to put livestock onto the recently fenced areas.

Monitoring of vegetation, insects and other key species ensures that the Dyke is managed appropriately.

Areas of shrubs are retained on the banks in order to provide suitable habitat and cover for birds and insects. Hedgerows on either side of the Dyke act as wildlife corridors and as a buffer to surrounding arable land .

The southern section of the Dyke is mature woodland. This is to be maintained with some areas of hazel being traditionally coppiced on rotation.

Access to the Dyke is to be improved by installing steps on some of the more steep, slippery slopes. Stiles will be replaced with gates to improve access. Finger posts and waymarkers will be replaced and paths well maintained. Interpretation panels will also be installed at appropriate points.

Thereafter, working with landowners and managers, the aim is to manage the Dyke in a more sustainable way with sheep grazing or mowing regimes established over the majority of the length of the Dyke. new hedge
