Cleddon Bog

[1] The bramble Rubus trelleckensis, which is endemic to Monmouthshire, is present at the site.

[2] Other plant species present include cranberry (Vaccinium oxycoccos), bog asphodel (Narthecium ossifragum), round-leaved sundew (Drosera rotundifolia), bottle sedge (Carex rostrata) and heath spotted orchid (Dactylorhiza maculata).

The site's interfaces between boggy heathland and woodland, with patches of bilberry and heather grow under an open canopy of rowan and other deciduous trees, means that it is home to a variety of important lepidoptera species for Wales such as the Bilberry Pug and welsh wave moths.

A total of 57 nationally notable or local species of butterfly and moth have been recorded on site.

The heathland moths have also declined, with some species not being recorded in recent years.
