caption_attribution_description: English: Ockham Common heath maintenance These sandy soils are home to many of our threatened heathland species - lizards, snakes, birds and insects. If they are not actively maintained, birch, pine, and rhododendron invade leading to local extinctions. The clearance shown in this photo may look devastated, heather will quickly re-establish.
context_page_description: Ockham is a rural and semi-rural village in the borough of Guildford in Surrey, England. The village starts immediately east of the A3 but the lands extend to the River Wey in the west where it has a large mill-house. Ockham is between Cobham and East Horsley.
context_section_description: The soil of Ockham Common varies between fertile light clay and humus topsoil to highly acidic, sandy heath. In the north is the high, uneroded Bagshot Sand. The southern part of the parish is on the London Clay. Part of the Wey Valley in the west of the parish and the banks of a stream which joins it from the east are particularly formed from alluvium.
caption: Ockham and Wisley Commons support rare species in their nationally rare soil type, acid, naturally wet sandy heath and bog soil.
