Type

This site is designated due to its biological qualities: Marsh orchids (Dactylorhiza incarnata) are exceptionally abundant. SSSIs in Wales have been notified for a total of 142 different animal species and 191 different plant species. Scarce plants include fewflower spikerush (Eleocharis quinqueflora) and marsh arrowgrass (Triglochin palustris).

Portheiddy Moor lies on the sloping southern side of the valley separating Barry Island from the mainland. The valley is known as the "Abereiddi meltwater channel", and is a product of sub-glacial meltwater erosion during the Ice Ages.
