A large-scale conservation project at Sandy in Bedfordshire to turn a working sand quarry into land that will support an array of wildlife and nature, is paying off after an exciting discovery.
For the first time in Bedfordshire a liverwort (a small flowerless plant with lobe like leaves) called Weedy Frillwort, so called due to its ‘frilly’ yellow green leaves, has been recorded, along with other rare species of mosses, liverworts, lichens and fungi. This tiny plant is easily overlooked at just 5mm long.
This exciting discovery was made by local expert plant surveyors in restored areas at Sandy Heath Quarry, which is managed by the RSPB and Tarmac as part of The Lodge nature reserve.
The RSPB is working in partnership with Tarmac, a UK leading sustainable construction solutions business who own the working quarry near the RSPB nature reserve and quarry sand for use in the construction industry. Together we are gradually restoring the quarried areas into 80 hectares of wildlife friendly land, providing a home for a diversity of species and allowing nature to reclaim the land.
Progressive restoration of Sandy Heath Quarry started in the 1990s and since the early 2000s both organisations have been working on this project together. The restoration of this site has and will continue to create a selection of wildlife friendly habitats including:
Each habitat will encourage insects, birds, reptiles and mammals to move in.

Peter Bradley, Senior Site Manager at RSPB The Lodge said, “The landscape at the quarry really is quite literally awesome – parts look like the surface of Mars! Helping to bring life to this landscape with Tarmac is truly inspiring, as we work together to produce the many different habitats for nature at this site.
“The discovery of this liverwort, a first for Bedfordshire, along with so many other rare species, shows how thoughtful restoration of quarries can provide the right conditions for nature to thrive. We look forward to many more years of working together with Tarmac and seeing much more wildlife calling this special place home.”
We are gradually converting some of the woodlands there from conifers to native broad-leaved woodland which will support more native wildlife such as Spotted Flycatcher, woodpeckers, Nuthatch and Tawny Owl. Arable land is planted with winter seed crops which form a ‘living bird table’ to help to feed birds through the winter such as Reed Bunting, Linnet, Chaffinch, Brambling, Meadow Pipit, Skylark, and Grey Partridge.
The topography of the site has also been changed to create structure and give wildlife and nature places to live and hide; including forming huge U-shaped valleys, a dry riverbed, ‘sink holes’, shallow cliffs, and drumlins (small hills).
On the edge of the working quarry, Tarmac has created a sand cliff for Sand Martins who return to the site each year to breed. Sand Martins nest in burrows excavated into sandy cliff walls and the colony, which can consist of several hundred birds, return to Sandy in the spring to breed from their wintering grounds in Africa. They then migrate back to Africa in the autumn. The Sand Martins are not disturbed by the sound of nearby quarrying and can be seen swooping in and out of their burrows as they leave to catch flying insects, then return to feed their young.

The vertical cliff face they nest in is tens of metres tall and the different coloured layers of strata clearly show different points in time as the land formed over millions of years. The rock in the cliff face formed in the Cretaceous era, the time of the last dinosaurs, 60 million years ago.
Enrique Moranmontero, National Restoration Manager at Tarmac, said: “Sandy Heath Quarry is a great example of how mineral operations and conservation organisations can join forces, securing the products needed for our day-to-day life and having a positive impact for nature. It is very exciting to see how the site keeps evolving and new species establish there.”
Due to it being a working quarry, the site is closed to the public, however it can be seen at a distance from the Skylark trail opposite the entrance to RSPB The Lodge nature reserve in Sandy. Parking is available at the nature reserve.
