GREAT SPOTTED WOODPECKER
Dendrocopos major

Conservation listings

Europe: no SPEC category, secure
UK: Green

Long-term trend
UK, England: rapid increase
Status summary
This species increased rapidly in the 1970s and began a further increase in the early 1990s. Dutch Elm Disease, which greatly increased the amount of standing dead timber and its associated insects, has been linked to the 1970s increase (Marchant et al. 1990). The ecological factors underlying the current increase are not yet known, but the species may be benefiting from the maturation of new forests and from the increasing provision of winter food in gardens. Brood size appears to be decreasing, but NRS data are sparse for this species.
