Dersingham Bog

It is notable for a rock dating from the Lower Cretaceous Period known as 'Dersingham Formation' which has been important in understanding the geology of the region.

The mire's make-up of wet acid peat makes it ideal conditions for some rare and diverse species of plants such as bog asphodels (Narthecium ossifragum), round-leaved sundew (Drosera rotundifolia), white beaked sedge (Rhynchospora alba) and cranberry.

The mire also has some rare insects such as the black darter dragonfly (Sympetrum danae) and moths such as the light knot grass (Acronicta menyanthidis).

The mire lies on shallow peat and is bordered on one side by a steep escarpment containing large areas of dry heath and woodland which marks the edge of an ancient coastline.

The woodland glades attract birds such as redpoll, crossbill, long-eared owl, tree pipit, woodlark, shelduck, nightjar, and sparrowhawk.
