of the Grade II listed derelict old brewhouse, part of the old stable block, to create an exhibition and discovery centre. Site of Special Scientific Interest In 1981 an area of was designated an SSSI. A wide variety of species-rich habitats surround the former mansion, including the lake and wetlands, grassland, heath and mature deciduous woodland. The mature trees and dead and decaying ancient trees provide good habitats for beetles. There are breeding birds of woods and heath including nightjar, woodlark, redstart, hawfinch, water rail and gadwall ducks. Ancient breeds of English Longhorn cattle and Jacob sheep have been introduced to pastures surrounding the lake as part of the process for managing the grassland habitats while safeguarding rare livestock breeds. In January 2018 the National Trust sent a "heartfelt letter" to the environment manager at fracking company Ineos, asking her to visit the park and to stop its survey there for shale gas reserves.
