Once a large freshwater lake, this unusual wetland habitat has a number of rare plant species. A speciality of the site here is the delicate bird's eye primrose, whilst other species include the black bog-rush, wild columbine and fragrant orchid. To the north of the wet area is a woodland of mainly Scots pine with birch and sycamore. Hazel and holly form a shrub layer in places and you can find early dog violet and herb Paris.
