The Major Oak's Death Signals a Wider Crisis for Britain's Ancient Trees

The Major Oak, a 1,200-year-old pedunculate oak in Sherwood Forest, has died after failing to produce leaves in spring 2026—the first clear sign its life has ended. Climate-driven heat waves and drought are partly responsible. The death matters because ancient oaks lack drought tolerance; their roots depend on stable moisture and mycorrhizal networks that cumulative dry summers progressively weaken. This isn't unique to one tree. Successive dry seasons are now a regular feature of the British climate, threatening veteran oak populations across the UK.
