The site comprises a small upland valley which
supports a diverse mosaic of unimproved pasture, 'ffridd' land, wet
flushes and small valley mires. The 'ffridd' areas are of
importance for birds, particularly nesting whinchat, tree pipit,
yellowhammer and linnet. Three species of fritillary butterfly ‑
marsh, small pearl‑bordered and dark green occur at Cefn Blaenau.
Another species of particular note found in the wet flushed areas
is the nationally uncommon keeled skimmer dragonfly.
