Transition mire and wet woodland of international importance with remnants of heath, wood pasture and acid/neutral grassland.
Emer Bog is an excellent example of a lowland valley mire. It has a rich flora and fauna dominated by bog species including reeds and sedges. Downstream, the bog gives way to a mature alder carr, whilst upstream, it moves into heathland with pine, birch and scrub. Baddesley Common contains remnants of former common land. Today, it forms an acid grassland dominated by purple moor grass, cross-leaved heather and meadow thistle.
