Biology
The hill's vegetation is species-rich chalk grassland, dominated by Upright Brome and False Oat-grass, but with many species characteristic of this habitat, including a strong population of the rare Knapweed Broomrape. This vegetation has led to a 2.3 hectares (5.7 acres) area of the site being notified as a Site of Special Scientific Interest, this notification initially being given in 1965. The site is unique in that its slopes have 360-degree aspects, allowing comparison between growth of the flora on the differently-facing slopes of the hill.
