Across the remote reaches of Scotland’s west coast and its islands, volunteers are scouring the landscape for rare seeds—tiny vessels of genetic memory that trace their lineage back to the last Ice Age. More than just planting stock, these hand-collected seeds possess unique adaptations vital for resurrecting the ancient woodlands that once blanketed much of the nation.
Launched in 2023, the joint initiative by Trees for Life and Woodland Trust Scotland has proven to be a resounding success. Far exceeding the original target of one million, volunteers have amassed over 11 million seeds from rare and elusive species over the past three years. A team of roughly 100 volunteers, operating in remote areas that are unprofitable for commercial nurseries to reach, surpassed the project’s target elevenfold. This vast collection has the potential to yield approximately 7.8 million new trees. The seeds were gathered from the western regions and Scottish rainforests, where trees have maintained unique genetic traits that bolster their resilience against disease and a changing climate.
The species collected include hazel, oak, dwarf birch, willow, juniper, wild cherry, wych elm, yew, and elder. Every seed is processed at the Dundreggan rewilding center, home to a specialized Trees for Life nursery. From there, the verified seeds are distributed to accredited nurseries throughout Scotland. All participating nurseries belong to the "UK and Ireland Sourced and Grown" scheme, which ensures the local provenance and high quality of the saplings. Originally planned as a three-year endeavor, the project has already been extended by at least another year following its remarkable success.
Today, Scotland stands as one of Europe’s least forested nations. Woodland covers only about 18% of the land, far below the European average of 37%. Native forests account for a mere 4% of the landscape, and over half of these remaining areas are considered to be in poor condition. The legendary Caledonian Forest in the Highlands, once a haven for red squirrels, capercaillie, and crossbills, has dwindled to less than 2% of its former range. Only about 30,000 hectares of unique temperate rainforest remain on the west coast, representing a critically rare ecosystem in urgent need of protection. These regions feature a hyper-oceanic climate marked by high rainfall and mild winters, providing the perfect habitat for rare mosses, liverworts, and lichens. Harvesting seeds with local genetics helps address a severe shortage of saplings with verified provenance while strengthening the resilience of future forests against disease and climate volatility.
Dundreggan serves as the project’s flagship site. The rewilding center is situated on a 4,100-hectare estate in Glenmoriston, purchased by Trees for Life in 2008. It houses a specialized nursery that produces approximately 80,000 trees annually from locally sourced seeds. The nursery focuses on rare species like dwarf birch, mountain willow, and aspen, which have nearly vanished from the Scottish landscape. The entire process—from collection and testing to cultivation—relies on volunteers who not only address the sapling shortage but also build a community of people personally invested in ecological restoration. Project coordinators view the initiative as a profound act of stewardship for future generations and Scotland's biodiversity.
Every seed collected holds the promise of a full-grown tree, and together they have the power to breathe life back into landscapes once thought lost. This effort is part of the ambitious Affric Highlands project, a 30-year initiative spanning over half a million acres that aims to become the UK's largest rewilding effort. Such initiatives demonstrate that ecological recovery begins with the patient, diligent labor of many hands in the most remote corners, all united by the goal of restoring the ancient forest to its former glory.
