Site Description: An exposed pocket beach, situated at Crawfordsburn Country Park (EHS) on the southern shore of outer Belfast Lough. Rock ridges and pebble/stone areas occur which house a very patchy Fucus vesiculosus flora. A freshwater stream flows over the pebbles giving rise to an Ulva intestinalis (originally recorded as Enteromorpha intestinalis) and Porphyra purpurea flora. The transect site is on a horizontally narrow intertidal beach of coarse sand. Backing is a concrete stone sea wall with grass and wood behind. It is popular for recreation being situated in a Country Park. The upper shore is steep dry coarse sand and shell gravel with little infauna. The mid and lower shores are less steep and have wet coarse and medium sand layers. Arenicola is present in the middle shore and Lanice in the lower, although neither are abundant. Wave action appears to structure the sand layers causing them to be highly mobile towards the lower shore.
