Oaks are biodiversity powerhouses – a single oak tree can support up to 2,300 species, more than any other native UK tree. Birds nest in bark crevices, bats roost in old woodpecker holes, and insects thrive in the canopy.
Trees are often the home of invisible ecosystems – for example, aphids, ants, fungi, mosses, and over 700 species of lichen live on and around oak trees.
Dead wood is a critical habitat and food couse for stag beetles throughout their entire 3-to-7-year life cycle. Larvae burrow into rotting logs, stumps, and buried timber to feed on the wood, while adult females lay eggs in the soil near the wood sources.
