National Tree Week
National Tree Week begins on November 25 and continues until December 3. It marks the start of the tree-planting season, providing a wonderful opportunity to celebrate trees. If possible, volunteers can join tree-planting activities organized by local groups and conservation organizations. If planting isn’t an option, consider finding some “Tree Time” to connect with nature in other ways.
Trees play essential roles in ecosystems around the world. They offer food, shelter, and habitats to many species while stabilizing eroding riverbanks. More importantly, as climate change remains a major issue, trees help mitigate it by capturing carbon dioxide, a key greenhouse gas, in their tissues and releasing oxygen.
Background
After the last Ice Age ended about 9,000 years ago, Scotland’s native trees and shrubs began to populate the landscape. Ancient oaks, Scots pines, and Caledonian pines once covered the region, but various events have reduced tree numbers over the centuries.
More than 4,000 years ago, cooler and wetter climates limited tree growth on higher ground. At the same time, woodlands were cleared for farming, a trend that has continued for centuries to make space for housing and infrastructure. In the early 20th century, World War I led to further deforestation, though the Forestry Commission, founded in 1919, aimed to restore Britain’s woods. While large pine plantations were created, conservation efforts now focus on diverse species to provide better habitats for wildlife.
In recent years, severe winter storms like Storm Arwen in 2021 caused significant tree loss in Scotland. Disease has also taken a toll, including Dutch Elm disease, which has destroyed many elms across the country.
The Future
Following devolution, the Scottish government assumed responsibility for forestry and established Scottish Forestry, focusing on native woodlands and conservation. Across Scotland, volunteers, conservation groups, and private estates are planting trees to increase biodiversity. For example, Project Laxford on the Reay Forest Estate in Sutherland aims to boost salmon numbers in the River Laxford by re-establishing trees along riverbanks. This project plans to plant one million trees to improve biodiversity and habitat health in the area.
Famous Trees
The Glen Affric Elm – The Last Ent of Affric: Known as “The Last Ent” after Tolkien’s tree creatures, this lone elm stands in Glen Affric, surviving Dutch Elm disease likely due to its remote location. Thought to be the last remnant of an ancient forest, it won Scotland’s Tree of the Year in 2019.
The Fortingall Yew: Estimated to be 5,000 years old, this yew tree in Fortingall churchyard is one of the oldest in the world. Once used in funerals, the tree is closely linked with life and resurrection, as its branches can re-root to grow anew. Over time, it has suffered damage from rituals, fires, and cuttings. In 2015, part of the tree even changed, sprouting red berries and showing signs of stress.
These trees reveal the complex ways humans impact nature, underscoring the importance of ongoing conservation efforts.
