The lesser spotted woodpecker is the UK's smallest and most rapidly declining woodpecker, with its welfare linked to the availability of dead and decaying wood in deciduous woodland.
Loss of old trees with standing deadwood through excessive woodland tidying removes both nest cavities and the invertebrate communities lesser spotted woodpeckers depend on for food. Competition for nest holes from great spotted woodpeckers and nuthatches is an additional pressure. Woodland management that retains and creates deadwood is the most important welfare measure.
