About a third of Banstead Downs lies in the north of Nork ward, where it is occupied by a golf course. Banstead Downs has been designated a Site of Special Scientific Interest. The golf course provides a mixture of types of grassland with a rich chalk flora (including a number of locally rare plants) and areas of mixed scrub important for birds. (Over the whole of these downs 57 species of bird have been recorded, of which 44 have bred.) In addition there is some more mature oak and hawthorn woodland. The invertebrate fauna includes very rare and localised species.
