Fferam Uchaf is a Site of Special Scientific Interest (or SSSI) in Anglesey, North Wales, for its exposures of Llanvirn (Ordovician) rocks. It has been designated as a Site of Special Scientific Interest since October 2001 in an attempt to protect its fragile Geological elements.Countryside Council for Wales website (Natural Resources Wales since 2013); accessdate: 30 December 2013 The site has an area of , is managed by Natural Resources Wales, and is north-east of Llanddeusant.
Type The site is designated due to its geological qualities. In Wales, geological sites range from quarries to rocky outcrops and massive sea-cliffs. Thirty percent of SSSIs in Wales are notified for geological and geomorphological features.
The site has a number of small rock outcrops including a quarry on farmland approximately and is considered to contain the best examples of Llanvirn rocks in Anglesey, a Series that is otherwise poorly represented in North Wales.
