What is this habitat?

The almost magical beauty of the Cotswolds in spring and summer defies the term “unimproved grassland”. Growing on soil that is based on limestone, these grasslands can be brim-full of wild flowers, butterflies, bees and many more creatures. They are lost when they are “improved” for farming by reseeding and fertilising. Created long ago when humans cleared the forests, this is a fragile haven for species that could not survive without it.

Why is this habitat at risk?

In the 1930s, limestone grassland covered 40% of the Cotswolds area. Now it covers just 1.5% – which is over half of the UK’s total area of this habitat.  Limestone grasslands must be appropriately managed to maintain their special wildlife. They need the right livestock grazing to prevent them becoming overwhelmed by scrub and young woodland, and the fertility of the soil must remain low if the special plants are not to be out-competed and lost.

How we will bring back the Cotswolds limestone grassland

This Back from the Brink project, led by Butterfly Conservation, will work with landowners to restore and manage a network of grassland sites in the Cotswolds. We will provide specialist advice to landowners and train up volunteers to help us monitor the impacts of management on a host of species, including the Red-shanked Carder Bee, the Duke of Burgundy and Marsh Fritillary butterflies, Fly Orchid, Basil Thyme and the rare Greater Horseshoe Bats.

We will reintroduce threatened butterflies and engage with volunteers and local communities to connect them with this precious wild heritage.

What we’re aiming for

By the end of the project, we aim to ensure the recovery and long-term viability of this vulnerable habitat and the species that rely on it. We hope to have enabled communities in the area to understand and appreciate these wonderful grasslands.
