Status summary

Green Woodpecker populations have increased steadily since 1966, except for a period of stability or shallow decline centred on the late 1970s. Recent results indicate that the current phase of increase is continuing across most of the UK range, although the Welsh population appears to be stable. The ecological factors underlying the increase are not yet known.
