Cors Goch

The Cors Goch reserve is one of several lowland fens on Anglesey and you can find it between the villages of Pentraeth and Benllech. The reserve lies in the bed of an ancient glacial lake. Over time, the lakes ancient hollow has filled in with peat, as plant life thrived and died through the past 10,000 years - leaving the fen we see today. Like the other wetlands on Anglesey, Cors Goch is an outlying refuge for many plants more often associated with the fens of East Anglia.

Visiting

The main access point to the reserve lies at the northeast end of the site. A path runs the length of Cors Goch for about one-and-a-half kilometers and there is a boardwalk through the fen, although this can be uneven when there’s a high water level.

There are no surfaced paths on the reserve and the terrain varies from flat to quite steep.Some uneven short stretches are unsuitable for wheelchairs or prams.

The paths can also get extremely wet and muddy with poor weather conditions.

Wildlife

Next to the lowland fen habitat, there are also areas of open water, heath and grassland due to the nature of the underlying geology.

The lime-rich swamp supports plants such as:

Great pond sedge
Bottle brush sedge
Common reed

While the lime-rich fen is characterised by species such as:

Black bog rush
Blunt-flowered rush

On the drier heathland and grassland areas flowers lie amongst the heather and cross-leaved heath, including:

Bog asphodel
Western gorse
Pale heath violet
Fragrant orchid

A diverse range of orchids, including green-winged orchid, thrive in the grassland. Additional rare plants include:

Marsh dandelion
Narrow leaved marsh orchid (nationally scarce)
Fen pondweed (nationally scarce)

The rare dwarf stonewort can be found in areas of open water.

It is also an important site for both breeding and overwintering bird species, and – given the huge range of fauna - a particularly rich invertebrate assemblage, with:
