The Major Oak has died. This enormous tree, which stood in Sherwood Forest in Nottinghamshire for roughly 1,200 years, failed to produce new leaves this spring—the clearest sign that such an old tree has reached the end of its life. BBC News confirmed the death on June 18.

The tree was so old it began growing around the year 800. CNN first reported the news on June 17. For much of its very long life, the Major Oak was the star attraction of Sherwood Forest. Steel supports held up its heavy branches for over a century. The ground around it was carefully protected so visitors wouldn't damage the roots.

Most people know this tree from the Robin Hood legend. According to the story, the outlaw sheltered inside its hollow trunk. Because of that connection, the Major Oak became one of Britain's most visited natural landmarks. Hundreds of thousands of tourists came to see it every year.

Why did such an ancient tree die now? CBS News pointed to heat waves and droughts caused by climate change. Scientists who study trees have noticed the same problem happening to old oaks across the UK over the past ten years. These ancient oaks need stable, wet soil to survive. Their roots are designed for that kind of ground. But summers in Britain are now regularly very dry. Year after year of drought weakens the underground networks that help the tree drink water. The tree doesn't usually die from one bad year—it's the buildup of stress over many years that finally kills it.

Now comes a harder question. What should forest managers do with the dead tree? The RSPB, Natural England, and local councils are involved in that decision. If they cut down the trunk to make the site safer for visitors, they lose something important: the tree becomes just wood. But if they leave it standing, the dead tree can still provide a home for beetles, spiders, bats, and rare fungi that live nowhere else. Keeping the tree in place—the new best practice for old trees—lets the forest ecosystem keep using it. Because this tree is so famous, whatever they decide will be watched closely.

There's a bigger picture here too. The UK government has promised to protect Britain's ancient and old trees as irreplaceable natural habitats. The Major Oak's death, linked to climate change, arrives while the government is working on net-zero climate goals and arguing about how land should be used. One tree's death doesn't prove climate change is destroying forests everywhere. But it's a real, visible example of the climate stress that old trees across Britain now face.

A tree that survived medieval times, plagues, religious upheaval, the Industrial Revolution, and two world wars did not make it through the first few decades of the 21st century's warming world. That is the simple fact. What happens next to this site, and to Britain's other ancient trees, is the story now unfolding.
