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.[1] The site has an area of, is managed by Natural Resources Wales, and is north-east of Llanddeusant.
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. Fferam-uchaf shows small but stratigraphically important outcrops, but is an important site for an understanding of Lower Ordovician palaeogeography.
