Long term trend
UK: rapid increase
Status Summary
Green Woodpecker populations have increased steadily since 1966, except for a period of stability or shallow decline centred on the late 1970s. The BBS indicates that the increases are continuing across most of the UK, although the size of the Welsh population appears to be stable. The ecological factors underlying the increase are not yet known.
