Grangelands and Pulpit Hill is a 25.5-hectare (63-acre) biological Site of Special Scientific Interest in Cadsden in Buckinghamshire.

[4][5] The site has grassland and scrub, which support interesting breeding birds and invertebrates, such as glow-worms and marbled white and chalkhill blue butterflies.

Further down the slope there is mixed woodland of recent origin where the beech trees are associated with a variety of other trees and shrubs including yew, ash, whitebeam and wild cherry, blackthorn, hawthorn and purging buckthorn.

[6][7] English Heritage (now Historic England) carried out an archaeological survey and investigation of the prehistoric hillfort in November 2000.

[8] The site is always open but accessibility is difficult for anyone who is not able bodied, due to steep slopes and soft ground.
