The Major Oak, a celebrated tree in Sherwood Forest estimated to be at least 1,000 years old, was confirmed dead after failing to produce leaves or buds. The ancient Nottinghamshire oak had an 11-metre girth and a canopy spanning 28 metres, making it one of Europe’s largest and oldest trees.
The tree attracted about 350,000 visitors each year and was linked in folklore to Robin Hood and his companions. It took its modern name from Major Hayman Rooke, a local historian who described it in 1790. Although the oak would not have been hollow during the period associated with the legend, later stories presented it as an outlaw sanctuary.
Experts did not attribute the death to a single cause. Arborist Reg Harris, who monitored the oak for nine years for the Royal Society for the Protection of Birds, pointed to a long combination of visitor and vehicle compaction, water-table changes associated with coal mining and significant climate shifts. He said limited summer rain over the previous five years and unprecedented high temperatures probably contributed substantially.
Past efforts to preserve the tree also affected how it aged. Supports and metal chains were added in 1904. During the 1960s, cavities were filled with concrete and limbs received coverings and fire-retardant treatment. The props kept the large branches standing but prevented the natural process in which an old oak sheds limbs and reduces its demand for water and nutrients. They could not later be removed without risking collapse.
Underground examinations found a deprived root system disconnected from nutrient-poor surrounding soil. During three winters, the RSPB carefully opened soil around the roots to improve aeration, nutrition and biological activity. Tests showed the soil recovering, but the tree produced very few leaves in its final living year and none in 2026.
The dead oak will remain standing because its habitat value continues. Woodland Trust conservation adviser Ed Pyne said deadwood supports forest species and that the Major Oak remained ecologically important despite its death. About one quarter of forest species depend on deadwood during some part of their life cycle.
Conservationists used the loss to draw attention to other ancient trees that lack specific legal protection. The Major Oak’s unusually high profile ensured that its decline was monitored and documented. Its death ended its living growth, but not its role as a large habitat structure, historical landmark and source of local folklore in Sherwood Forest.
England retains an unusual concentration of very large ancient oaks: 114 living specimens have girths above nine metres, compared with 98 across the rest of Europe, including Scotland and Wales. Conservationists compared their rarity with white rhinos. That wider population made the Major Oak prominent but not the only ancient tree facing similar pressures.
