The RSPB's primary conservation aim is to expand the area covered by the forest. On 24 August 2011 the RSPB received consent from the Forestry Commission to expand native woodland through natural regeneration and planting, since when they have begun the planting of 60,000 aspen, birch, juniper and willow trees within an area of approximately 590 hectares. They are also working to improve bog, moorland, scrub, rivers and mountain habitats, both within the area of the reserve and in partnership with neighbouring estates.
