The goat moth is a declining moth species whose larvae spend up to five years developing inside the wood of large old trees, making ancient woodland habitat critical to its welfare.
Goat moth welfare is tied entirely to the availability of large old trees with accessible heartwood for larval development. Loss of veteran trees through felling, damage or decline removes habitat for a species that cannot simply move to younger trees. A single large old willow or poplar can support multiple generations of goat moths across decades. Ancient woodland protection and veteran tree retention in urban and agricultural landscapes are key welfare interventions.
