Description:
One of the last remaining sections of the Swansea Bay Coastline which has remained
substantially unmodified by industrial development. Over the past one hundred and fifty
years, parallel sand dune ridges have developed at right angles to the River Neath and these
are continuing to accumulate at the present time. Salt water is able to gain access to the
system at high tide via the river channel, with the result that the dunes are interspersed by
tongues of saltmarsh. These grade westwards into wet dune slacks and carr woodland.
Several plant species with local distribution occur within the site including rock sea lavender
Limonium binervosum, dittander
Lepidium latifolium, rock hutchinsia
Hornungia petraea,
round leaved wintergreen
Pyrola rotundifolia, dutch rush
Equisetum hyemale and the
variegated horsetail
Equisetum variegatum. The rare fen orchid
Liparis loeselii is found
occasionally within the slacks, whilst the sea stock
Matthiola sinuata which was re-recorded
in 1964 following its earlier disappearance, is widespread along the strandline and in the
dunes.
The rare strandline beetle
Eurynebria complanata has been recorded from the site.
This part of the Neath estuary is also used by part of the population of small waders
overwintering in Swansea Bay.
