Description:
The main features of interest at Cae Gwyn
are two wetland areas, separated by an area of heathland with outcropping rock.
The southern wetland is confined by a rock basin; it has a 'lawn' of bogmoss Sphagnum
spp and a profusion of common wetland herbs such as bogbean Menyanthes
trifoliata and marsh cinquefoil Potentilla palustris. The flora is
distinguished by an abundance of royal fern Osmunda regalis which varies
from very large old plants to young plants; other notable species are bog sedge
Carex limosa and cranberry Vaccinium
oxycoccus. The northern wetland differs in having denser areas of willow and common reed Phragmites
communis, but is similar in having
numerous plants of Osmunda.
