Uskmouth (Welsh : Aberwysg) is an area to the south of the city of Newport, South Wales.

Welsh language Brythonic language spoken natively in Wales

Welsh or y Gymraeg is a member of the Brittonic branch of the Celtic languages. It is spoken natively in Wales, by some in England, and in Y Wladfa. Historically, it has also been known in English as "Cambrian", "Cambric" and "Cymric".

Newport, Wales City and County in Wales

Newport is a city and unitary authority area in south east Wales, on the River Usk close to its confluence with the Severn Estuary, 12 miles (19 km) northeast of Cardiff. At the 2011 census, it was the third largest city in Wales, with a population of 145,700. The city forms part of the Cardiff-Newport metropolitan area, with a population of 1,097,000.

South Wales Region of Wales

South Wales is the region of Wales bordered by England and the Bristol Channel to the east and south, mid Wales to the north, and west Wales to the west. With an estimated population of around 2.2 million, which is almost three-quarters of the whole of Wales, Cardiff has approximately 400,000, Swansea has approximately 250,000 and Newport has 150,000. The region is loosely defined, but it is generally considered to include the historic counties of Glamorgan and Monmouthshire, extending westwards to include Carmarthenshire and Pembrokeshire. In the western extent, from Swansea westwards, local people would probably recognise that they lived in both south Wales and west Wales. The Brecon Beacons national park covers about a third of South Wales, containing Pen y Fan, the highest British mountain south of Cadair Idris in Snowdonia.

Location

Uskmouth is effectively in the west of the village of Nash. It is at Uskmouth that the River Usk meets the Severn estuary.

Nash, Newport village in Newport, south-east Wales

Nash is a village and community to the south of the city of Newport, South Wales, in the Liswerry ward.

River Usk river in Wales

The River Usk rises on the northern slopes of the Black Mountain, Wales, in the westernmost part of the Brecon Beacons National Park. Initially forming the boundary between Carmarthenshire and Powys, it flows north into Usk Reservoir, then east by Sennybridge to Brecon before turning southeast to flow by Talybont-on-Usk, Crickhowell and Abergavenny after which it takes a more southerly course.

Amenities

It includes part of the Newport Wetlands Reserve , a notable wildlife reserve , with reed beds and grasslands that attract breeding birds such as lapwings, redshanks, oystercatchers, little ringed plovers and ringed plovers, as well as visitors such as wigeons, shovelers, teals, shelducks and pintails, bitterns, hen harriers and short-eared owls. It is part of the Caldicot Levels.

Grassland areas where the vegetation is dominated by grasses (Poaceae)

Grasslands are areas where the vegetation is dominated by grasses (Poaceae); however, sedge (Cyperaceae) and rush (Juncaceae) families can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica. Grasslands are found in most ecoregions of the Earth. For example, there are five terrestrial ecoregion classifications (subdivisions) of the temperate grasslands, savannas, and shrublands biome (ecosystem), which is one of eight terrestrial ecozones of the Earth's surface.

Bird Warm-blooded, egg-laying vertebrates with wings, feathers and beaks

Birds, also known as Aves, are a group of endothermic vertebrates, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the 5 cm (2 in) bee hummingbird to the 2.75 m (9 ft) ostrich. They rank as the world's most numerically-successful class of tetrapods, with approximately ten thousand living species, more than half of these being passerines, sometimes known as perching birds. Birds have wings which are more or less developed depending on the species; the only known groups without wings are the extinct moa and elephant birds. Wings, which evolved from forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in flightless birds, including ratites, penguins, and diverse endemic island species of birds. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming.

Northern lapwing species of bird

The northern lapwing, also known as the peewit or pewit, tuit or tew-it, green plover, or just lapwing, is a bird in the lapwing family. It is common through temperate Eurasia.

Following storms in the autumn of 1986, a track of human footprints was discovered eroding out of the clays in the intertidal zone in front of Uskmouth Power Station. The footprints were found to contain peat deposits, allowing them to be carbon dated to 4200BC. At the time they were the oldest known human footprints in Britain, [1] but in 2013 footprints made about 800,000 years ago were discovered in Happisburgh, Norfolk.

Clay A finely-grained natural rock or soil material that combines one or more clay minerals

Clay is a finely-grained natural rock or soil material that combines one or more clay minerals with possible traces of quartz (SiO2), metal oxides (Al2O3, MgO etc.) and organic matter. Geologic clay deposits are mostly composed of phyllosilicate minerals containing variable amounts of water trapped in the mineral structure. Clays are plastic due to particle size and geometry as well as water content, and become hard, brittle and non–plastic upon drying or firing. Depending on the soil's content in which it is found, clay can appear in various colours from white to dull grey or brown to deep orange-red.

Peat accumulation of partially decayed vegetation

Peat, also known as turf, is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem is the most efficient carbon sink on the planet, because peatland plants capture CO2 naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of 1.5 to 2.3 m [4.9 to 7.5 ft], which is the average depth of the boreal [northern] peatlands". Sphagnum moss, also called peat moss, is one of the most common components in peat, although many other plants can contribute. The biological features of Sphagnum mosses act to create a habitat aiding peat formation, a phenomenon termed 'habitat manipulation'. Soils consisting primarily of peat are known as histosols. Peat forms in wetland conditions, where flooding obstructs the flow of oxygen from the atmosphere, slowing the rate of decomposition.

Happisburgh footprints Set of fossilized hominid footprints in Norfolk, England

The Happisburgh footprints were a set of fossilized hominid footprints that date to the early Pleistocene, over 800,000 years ago. They were discovered in May 2013 in a newly uncovered sediment layer on a beach at Happisburgh in Norfolk, England, and carefully photographed in 3D before being destroyed by the tide shortly afterwards.

Footprint

Footprints are the impressions or images left behind by a person walking or running. Hoofprints and pawprints are those left by animals with hooves or paws rather than feet, while "shoeprints" is the specific term for prints made by shoes. They may either be indentations in the ground or something placed onto the surface that was stuck to the bottom of the foot. A "trackway" is set of footprints in soft earth left by a life-form; animal tracks are the footprints, hoofprints, or pawprints of an animal.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
