Its area is 121 hectares (300 acres), one of the Trust's largest reserves.
Bird species seen in the reserve include curlew, red grouse and short-eared owl.
[1] Moorland plants amongst the heather include bilberry, crowberry and cowberry; these attract particular species of butterflies, moths and other insects, notably the green hairstreak butterfly.
[1] Two-thirds of the reserve is moorland, and one-third is a conifer plantation, planted in the 1970s and never harvested.
The Trust plans in the long term to remove the plantation, so the land can be more beneficial to wildlife.
