Calvert Jubilee
From Wikipedia, the free encyclopedia
Calvert Jubilee is a 22 hectares (54 acres) nature reserve in Calvert near Steeple Claydon in Buckinghamshire. It is managed by the Berkshire, Buckinghamshire and Oxfordshire Wildlife Trust (BBOWT). In July 2020, High Speed 2 (HS2) announced it would take possession of 20% of the reserve and clear it.
Most of the site is a deep lake, created by the extraction of clay for the brick industry. The abandoned Great Central Main Line also passed through the site.[1] It is now used in winter by wildfowl such as mallard, tufted duck and pochard. There are two bird hides, and the trust has created three floating islands to enable waterfowl to breed safe from foxes. The lakeside has a variety of wild flowers and butterflies.[2] All of the UK's five varieties of hairstreak butterfly have been seen at the reserve.[3] It is managed by the Berkshire, Buckinghamshire and Oxfordshire Wildlife Trust (BBOWT) and there is access from the road which passes between Calvert Jubilee and Grebe Lake.[2]
