Newborough Warren

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 intertidal mudflats and saltmarshes are important wintering grounds for waders and wildfowl regularly supporting over one per cent of the British population of pintail.

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.

During the late 1970s and 1980s and mid-1990s there were concerns that the water levels within the forest and within neighbouring Warren were falling due to a greater potential evaporation demand caused by afforestation, with the result that winter flooding was not to the same depth and that dune slack pools were drying out sooner.
