Ecology

The common is described by Natural England as "one of the best examples in Britain of a lowland mixed valley mire". It has diverse habitats, including wet acid heath, calcareous fen and dry heath on acid sands. There are rare plants, birds and insects, including the black darter dragonfly.[9]

Uncommon plant species include black bogrush, marsh fern, cranberry, bog asphodel, common cotton-grass, all three species of sundew and sphagnum moss. The common also supports some uncommon dragonfly species such as the broad-bodied chaser. Many species of flowers grow in grassy clearings on the drier ground which attract butterflies such as green and purple hairstreaks and brown argus.

Access

There is access by footpaths including one from Pott Row which runs along the southern boundary
