Beach is located on the North West corner of Northern Ireland and stretches
from Downhill to Magilligan Point, close to County Donegal in the Republic
of Ireland. The beach is the foreward end of a cuspate foreland which
started to develop as a result of sea and land level changes after the
last ice age. Magilligan foreland is Irelands largest coastal accumulation
feature comprising 32 square kilometres of marine and wind-blown sand
This study is of a psammosere.
Sand dunes are dynamic elements of the landscape. They grow when sand is deposited on the beach by longshore drift or shoreward movement of sediment. As the sand dries between periods of high tide, it can be blown landwards and trapped by plants to become the beginnings of a sand dune system. The interrelationship between the mineral input (the sand) and the vegetation is what defines the development of the sand dunes. Where tidal range is low and sediment size is big, such as in the south of England, sand dunes are rare. In Ireland about 20% of the coast has sand dunes.
