Newborough Warren - Geomorphology

Geomorphology

There are large expanses of both active and fixed dunes, although many of the latter have been afforested, along with a freshwater lake, salt marsh and mudflats and a tidal island. The reserve contains an outstanding flora, interesting lichen and moss communities and a wealth of invertebrates. The intertidal mudflats and saltmarshes are important wintering grounds for waders and wildfowl regularly supporting over one per cent of the British population of Pintail. Ynys yr Adar, near Ynys Llanddwyn, supports over one per cent of the British breeding population of Cormorant.

At the extreme southern tip of the Warren is Abermenai Point, the location of probably the earliest ferry crossing over the Menai Strait to the Welsh mainland.
