MWT have purchased this expansive site thanks to a generous donation from Aviva, marking our charity’s transition from nature conservation towards both nature conservation and nature’s recovery.
In partnership with other charities, we will protect and enhance existing habitats of international importance at Glen Auldyn, whilst re-creating lost temperate rainforest within the bracken-clad valley itself.

Dogs
Welcome along footpaths and greenlanes only. All dogs must be on a short lead (no more than 3m in length) throughout the year owing to the presence of red-listed ground nesting and over-wintering birds and upland sheep and lambs.

An extensive and beautiful area of upland moorland and bracken-clad valley at the headwaters of the Glen Auldyn River. In time, this landscape will become the Island’s largest native temperate rainforest, which would have been the dominant landcover for the Manx uplands for thousands of years before Neolithic farming gradually cleared our native forests to make way for open fields.
Management:
During 2025, 2026 and 2027 sheep grazing will continue at Glen Auldyn as in the past, whilst we undertake detailed ecological survey work and gain planning permission to undertake tree planting, from 2027 on areas of bracken and similar low-quality habitat.
Once the new trees are established, we will reintroduce grazing across the reserve to create and maintain a rich mosaic of wildlife-rich habitats, including woodland pasture.
