The site includes part of King’s Wood, with Bragenham Wood and Rammamere Heath, and consists of heathland and ancient woodland, with areas of conifer plantation on both habitats. It is part of a larger SSSI and King’s Wood is an NNR.

A range of woodland communities are present including acid oak-birch woodland on sand and ash-maple woodland on boulder clay. Large stands of small-leaved lime are present and other rare species include adder, bilberry and a large population of lily-of-the-valley. Parts of the woodland have been managed by coppicing, and conifers have been removed to restore areas of broad-leaved woodland.

The open heathland is managed by grazing with Exmoor ponies and Hebridean sheep, and it is planned to remove most of the remaining conifers on the remaining heathland.
