There are 23 native woodland mammals and then a further 13 species of bats found in the UK. There are several species like the Red squirrel and Badger that are under threat and are monitored closely by wildlife organisations..
Grey Squirrel
Tree-climbing nut buriers. Scampering grey squirrels are a familiar sight, but sadly these American imports have had a disastrous impact on the native red squirrel.The red squirrel is smaller and is in decline as the grey squirrel has a bigger appetite and so there is not always enough food left for the red squirrels.
Voles
Bank voles are common and widespread across the UK. They don't hibernate so you can spot them all year round. Their burrows are often in grassy areas buried shallowly underground but can be above ground provided there is thick cover.
Red and Fallow Deer
The Red Deer is bigger than the Fallow Deer but are othen seen close together. They can be found in some local parks and wildlife reserves.
