Wildlife - Newborough Forest and Warren

Newborough Forest and Warren forms the southernmost corner of Anglesey, positioned between the Afon Braint and the Afon Cefni with its extensive estuary.

The Warren is a large sand dune system which has been designated as a Site of Special Scientific Interest (SSSI) for its geological, botanical, invertebrate and ornithological qualities.  The Warren (along with Llanddwyn Island) is also a National Nature Reserve (NNR), although the forest is not included within this designation.  There is a network of footpaths through the forest and across the Warren and onto Penrhos and Llanddwyn beaches.  There is a footpath across to Llanddwyn island, but it is cut off from the beach at high tide. The reserve is served by four car parks which are situated at the main access points.  The adjoining Malltraeth estuary holds large collections of wading birds, with the small and rarer waders often gathering on the Cob Pool and also the wildlife pool in the northern part of the forest.

The saltmarsh bordering the forest to the north west is especially good for hen harriers, merlins and other birds of prey in winter.  This habitat, in addition to the adjacent mudflats, provides important wintering grounds for wading birds and wildfowl, regularly supporting over 1% of the British population of pintail.  Ynys yr Adar, near Llanddwyn Island, supports a large breeding population of cormorant.  The forest is famed for its huge raven roost (up to 2,000 birds have been recorded), and other notable species include crossbills and siskins.  In the summer, the forest is permeated by the entrancing song of skylarks.  Red squirrels make their home here – the site is well known as one of their strongholds.  The sand dunes harbour many rare and interesting plants, such as butterwort, dune helleborine, dwarf adder's tongue and shore dock.  The area has a thriving invertebrate population, which includes scarce species such as the small red damselfly and the hairy dragonfly, as well as mining bees and the rare hoverfly Eumerus sabulonum.  There are medicinal leeches in some of the wet dune slacks, and even a population of great crested newts!
