Many of the Dartmoor farms still have old granite bee boles in situ.
Without being very plentiful anywhere, it is generally distributed in suitable localities throughout its range - those localities being such as afford it a sufficient supply of food, consisting during the greater part of the year of insects, which it diligently seeks on the boles and larger limbs of old trees; but in autumn and winter it feeds on nuts, beech-mast, the stones of yew-berries and hard seeds.
Bark has almost square plates as in U. procera, but still vertically fissured; large boles are fluted (Mitchell, 1974 ).
A further six tree boles were recorded within Intervention 18.
Down the faster runs and chutes, artfully wedged pine boles clog the current with trouty habitat.
