The aerial walkways provided by interlocking tree branches provide a home for the rare and elusive hazel dormouse. In autumn they begin to prepare for their winter hibernation by fattening up on nuts and berries. Other than bats, they are the only other British mammal that truly hibernates over winter. When the temperature falls below 15 degrees Celcius, their metabolism shuts down and they find a secure, dry place to build a nest and sleep.
