The smallest reserve on Anglesey
Porth Diana became a nature reserve in 1979, primarily to ensure the protection of the spotted rock rose, Anglesey's county flower. The reserve is part of the nationally important coastal heath on the west coast of Holy Island. Characteristic plants here include bell and common heather and in the open patches of grassland, wildflowers such as spring squill and English stonecrop can be seen. There is a healthy population of invertebrates, including green tiger beetle and mottled grasshopper
