Site details
Site description: The IBA of Mynydd Cilan, Trwyn y Wylfa ac Ynysoedd Sant Tudwal (Mynydd Cilan, Trwyn y Wylfa and the St Tudwal Islands) is located on the southern coast of the Lleyn Peninsula in North Wales. The site consists of a 10 km stretch of Atlantic vegetated sea-cliff and exposed sandy shore from Penrhyn Du in the east, to the eastern edge of Porth Neigwl in the west. These cliffs have adjacent habitats composed of unimproved permanent pasture, maritime grassland, semi-improved grassland, arable farmland, and coastal and maritime heath. The coastal habitats support an important resident population of Pyrrhocorax pyrrhocorax, which depend on the diverse mix of habitats present and their low-intensity agricultural management.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
Delineation rationale: First identified in 2007. SPA boundary used from JNCC; digitised at 1:10,000 scale.
