Fferam Uchaf

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. The site has an area of 1.05 hectares and is managed by Natural Resources Wales and is situated 1.5 km north-east of Llanddeusant.


This site is designated due to its geological qualities. In Wales, geological sites range from quarries to rocky outcrops and massive sea-cliffs. 30% 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.
