Ockham and Wisley Commons have been designated a Site of Special Scientific Interest and are part of a European Special Protection Area. The heathland on Ockham common is rare and is known for its beautiful purple heather in the summer. Wisley Common is wetter than Ockham and is home to many species of wetland plants and birds. Both commons have a large population of dragonflies and damselflies. A rare bird known as a hobby (a small falcon) can also be found here. There are two main trails that lead you through the woods to the commons.
