The surrounding woodland consists of Rowan, Holly, Alder Buckthorn (which supports a large Brimstone butterfly population), Silver Birch, Hairy Birch and Scots Pine (believed to have been planted in the nineteenth century as a timber crop). The insect groups present contain many uncommon species, including 22 species of [[dragonfly]], and several species of rare [[beetle]] which prefer the upright dead trees to fallen dead trees. | The surrounding woodland consists of Rowan, Holly, Alder Buckthorn (which supports a large Brimstone butterfly population), Silver Birch, Hairy Birch and Scots Pine (believed to have been planted in the nineteenth century as a timber crop).
