As a seedling, the tree's first leaves would attract green flies and saw flies which nibble into the leaves, and warblers and titmice eat the flies. Gall wasps work their way into the young bark. When it becomes a sizeable tree, other plants grow in the leaf drop, ferns and tiny mosses. Birds nest and eat insects on the trunk and leaves.
A mature tree houses more species than it is in years itself - rich in wildlife including squirrels, bats, jays, woodpeckers, blackbirds, woodmice, dormice, rabbits, foxes, millipedes, centipedes, butterflies, beetles, wasps, ants and owls.
In 2011 we had a family of Tree Creeper birds roosting in the tree.
