A project using drones to disperse tree seeds could "revolutionise" the expansion of rainforests in South West England.
The Woodland Trust says 75,000 seeds have been scattered on hills which would be inaccessible for human planting by hand.
The drones, which seeded 11 hectares of land around Bodmin in eight hours, scattered tree seeds native to rainforests, including pedunculate oak, alder, wild cherry, downy birch and hazel.
