About the reserve

This unusual nature reserve was once a mineral quarry, since reclaimed by nature. The grassland is striking, with hollows and banks providing sheltered hummocks of acid grassland which come alive in summer with insects. A colony of rabbits grazes the grassland, leading to an abundance of wildflowers that you can now see in open areas.   

History of Dews Farm Sand Pits

Dews Farm was once a mineral quarry, abandoned several decades ago when sand and gravel extraction ended. Nature has reclaimed the site and now a fascinating array of wildlife is present.   Facilities at Dews Farm Sand Pits There are no facilities available at the reserve.
