Newborough Warren, in the south-west of the Welsh island of Anglesey, is one of the finest examples of a sand-dune system in Britain.

This National Nature Reserve consists of a large area of sandhills and dune grasslands and there are four main ridges separated by hollows known as "slacks". A large area of dunes close to the reserve has been planted with Corsican Pine and is now known as Newborough Forest.

The Llyn Parc Mawr is a freshwater pool with two nearby hides within the forest. The remaining dunes, which are made up of a large proportion of powdered seashells and thus are high in calcium, have a very rich and varied flora with many scarce species present.

As well as sand-dunes the reserve also consists of a rocky peninsula, Ynys Llanddwyn, and an area of saltmarsh in the east of the Cefni Estuary[Map] including Malltraeth Pool, a noted wader haunt. This range of habitats attracts a variety of birds to Newborough Warren and the area is good for wintering waterfowl and waders.


Notable Species

Breeding species include Canada Goose, Common Shelduck, Common Teal and Red-breasted Merganser as well as Common Kestrel and Eurasian Sparrowhawk. Waders present in summer include Oystercatcher, Ringed Plover and Northern Lapwing and both Great Cormorant and Shag breed at Ynys Llanddwyn.

Sandwich Tern is a common migrant and other terns possible in the Newborough Warren area are Common Tern, Arctic Tern, Little Tern and even Roseate Tern. Sedge Warbler and Grasshopper Warbler breed in the marshy slacks and Common Crossbill, Coal Tit and Goldcrest in Newborough Forest.

During passage periods and in winter the range of species increases with waterfowl such as Bewick's Swan and Whooper Swan, Eurasian Wigeon, Northern Pintail and Northern Shoveler and waders include Purple Sandpiper, Ruff, both godwits, Spotted Redshank and Greenshank.

Divers including Great Northern Diver and grebes including Slavonian Grebe can also be seen in winter. Short-eared Owl occasionally breeds but is a regular winter visitor as are Merlin and Hen Harrier. Golden Pheasant was introduced to the area in the 1970s and small numbers remained for a few years but appear to have died out.

More than 550 plant species have been recorded at Newborough Warren with species such as Sea Spurge Euphorbia paralias, and Dune Pansy Viola curtisii growing amongst the Sand Catstail Phleum arenarium and Marram Grass Ammophila arenaria on the younger dunes. More established dunes have Cuckooflower Cardamine pratensis, Birdsfoot Trefoil Lotus corniculatus, Lady's Bedstraw Galium verum and Meadow Saxifrage Saxifraga granulata. Grass-of-Parnassus Parnassia palustris,

Round-leaved Wintergreen Pyrola rotundifolia and Yellow Birdsnest Monotropa hypopitys grow in the slacks between the dunes along with orchids including Northern Marsh Dactylorhiza purpurella, Early Marsh Dactylorhiza incarnata and the very rare Dune Helleborine Epipactis helleborine.

The Cefni Estuary has one of Britain's largest stands of Sea Rush Juncus maritimus as well as Sea Aster Aster tripolium, Annual Sea-blite Suaeda maritima and Sea Arrowgrass Triglochin maritimum while the rocks of Ynys Llanddwyn are home to Golden Samphire Inula crithmoides and Spring Squill Scilla verna.

To do

Areas of Interest

Return to Newborough village and turn right at the second crossroads and head towards the beach after paying a car-parking fee. The car-park has toilets and information and the peninsula of Ynys Llanddwyn [Map]can be reached on foot from here.

From Newborough village head east to a roundabout and then sharp right to the reserve entrance. Llyn Rhos-ddu[Map] is a freshwater lake with densely vegetated margins close to the reserve entrance. Overlooked by a hide, the lake has some waterfowl including Ruddy Duck.

There are several footpaths over the dunes and through the forest, all of which are worth exploring but to protect this fragile environment it is important to keep to the paths.

Access and Facilities

Newborough Warren is located at the south-western tip of Anglesey and can be reached on the A4080 road which passes through Newborough village to the Cefni Estuary.

The area can be viewed from the road or from the embankment known as Malltraeth Cob.
