Our work at Dunstable Downs

Wildlife returns

It takes considerable time and management to start to see the benefits, but we’re already starting to see change. Ground-nesting birds are returning – including skylarks, meadow pipits and yellowhammers.

Red kites, buzzards, barn owls and kestrels now hunt over the grassland. We’ve also spotted deer, foxes, rabbits and field mice.

The benefit is not just the increase in wildlife, but also a reduction in the risk of soil erosion and help in locking up carbon from the atmosphere.

It's not just the Downs that we look after

It’s not just Dunstable Downs we care for, but Whipsnade Tree Cathedral, Totternhoe Knolls and Sharpenhoe Clappers – 10 sites in total.

Whether it’s clearing scrub, mowing grass, repairing fences, clearing paths, monitoring wildlife or inspecting habitats, the team come out in all weathers, to help. Ninety per cent of the countryside team are volunteers and we couldn’t do it without them.

The work begins

Summer is the busiest time for most people at the Chiltern Gateway Centre, but for the countryside team, the main conservation work is carried out as the weather gets colder.

Whilst birds are nesting and the chalk grassland plants are in flower, the team are careful not to disturb them, but from late August the real work begins.

Chalk grassland is cut

Chalk grassland flora thrives in soil that is low in nutrients. Once the plants have gone to seed the grassland can be cut, the material removed and usually burned in designated areas, or removed from site. This is to remove the nutrients stored in the plants.

This process is carried out between August and December with brush-cutters, to stop scrub returning. We leave some grass uncut as refuge areas for small mammals and to provide a seed source for birds over winter.

Tree surveys take place

Autumn is also a perfect time for the fungi species that live in the trees and on deadwood. Consequently, this is when we check the health of our trees on all our sites. Surveys carry on from September through to December and trees may have to be felled if a harmful fungus or disease is detected.

Chute Wood

This much-loved wood has sadly become the victim of disease and requires a complete fell. In early 2022, work was carried out to remove all of the diseased ash trees which enabled it to be open for summer 2022.

Over the winter of 2022/23, the site was removed all the remaining diseased trees and with the help of our local community, and generously supported by the Rotary Club, we replanted Chute Wood with native broadleaf trees.

Sharpenhoe Clappers

Woodland work is also carried out at Sharpenhoe Clappers to remove self-seeded ash saplings, which are growing too close together, and are at risk of damaging the archaeology below ground.

Arable reversion meadows

In the meadows, the hay cut may look like a bad haircut, but each meadow requires a different cutting technique.

• One meadow is grazed by sheep in early spring and had a much later flowering period. This was a popular spot for second broods of skylarks, so was left untouched
• Most of the meadows have been forage harvested, but five per cent of the summer’s growth was left for birds to nest in over winter
• Another field which was grazed by sheep in late spring was cut into strips, to keep a nectar source for pollinators throughout the field.

Pruning the fruit trees

In the jubilee orchard the fruit trees are still young, so benefit from formative pruning. From late summer the stone fruit trees can be pruned, and the surrounding meadow has a final cut before winter.

Tree planting at Dunstable Downs

We’ve drawn up plans to plant 3,600 trees at Dunstable Downs to create new woodland and wood pasture habitats for wildlife. Trees will be planted next to existing woodland areas which contain important woodland flower species such as bluebell, greater stitchwort, yellow archangel and wood anemone. Making the woodland areas larger will allow these flowers to spread. We'll be planting a wide variety of native species of trees and shrubs that are attractive to wildlife, and which have been selected for their ability to cope with the projected models of climatic change. The variety of species includes oak, hornbeam, wild cherry, silver birch, small-leaved lime, hawthorn, hazel, willow, and crab apple. The scheme combines planting woodland blocks to expand existing belts of trees with the creation of a grazed wood pasture that contains thickets of scrub and clumps of trees. The grazing animals will include cattle, which create a diversity of structure within the grassland area that will provide opportunities for insects, birds and small mammals to live and breed. Wildflowers growing in the grassland will also provide pollen and nectar for bees and butterflies.

Why not more trees?

By retaining some areas as grazed pasture, we’ll be preserving the setting of the Whipsnade Tree Cathedral that currently sits within a relatively open landscape. We’ll also ensure that we retain a sightline extending out from the nave of the Cathedral, giving a fantastic view into the surrounding landscape.

Where will this take place?

The two fields that form part of this project are adjacent to the Whipsnade Tree Cathedral, just a 20 minute walk from the Chilterns Gateway Centre. Public footpaths run along the northern and southern edges of the fields. In addition, a new route is proposed through the centre of the newly planted woodland. This is designed to minimise contact between livestock and pedestrians. New benches will be installed where visitors can pause to take in the views.

Have your say

The plans will be displayed in the Chilterns Gateway Centre until Friday 4th August and we’d like to hear your comments. There is still a chance to help shape the final outcome of the design, so please do drop in and leave your feedback, or you can email us with questions and comments at dunstabledowns@nationaltrust.org.uk

Thank you

With your ongoing support, we're able to continue our vital conservation work. Thank you for helping to protect these special places.
