Marine Nature Conservation Review Intertidal Survey of Rhos Point to New Brighton
The results of intertidal surveys carried out on the flora and fauna of sixteen sites within a survey area along the southern coast of Liverpool Bay. The shores within the survey area were mainly sediment shores however at some sites rocky substratum was present. The purpose of this data capture was to describe a representative range of intertidal habitats and their associated flora and fauna from locations on the open coast distributed throughout the survey area. The survey was part of the Marine Nature Conservation Review which had the aims of extending our knowledge of British marine ecosystems, identifying sites of nature conservation importance and providing information to support more general measures required to minimise adverse effects of development and pollution. The sampling area extends from Rhos-on-Sea in the west to New Brighton in the east, (approximately 50 km) and comprises of the majority of the southern coast of Liverpool Bay. All sites were surveyed between the 23rd - 25th of May 1990, and some sites were subject to additional visits on the 17th and 18th of September 1990.

Sites were chosen to provide a representative range of intertidal habitats. At soft sediment sites macrofauna was sampled using four cores of 0.01m2, to a depth of 15 cm. Hand-digging of approximately 1m2 at each site and observations of cast, tubes etc gave information on the larger more sparsely distributed species. Sediment was also taken from each station for granulometric analysis. The survey methods for the hard substrata sites involved taking samples of barnacles from different locations at all sites to check their identity and scrapes of mud encrusting rocky surfaces were also taken in order to identify their flora and fauna. The biological interest and conservation importance in terms of sites, habitats, communities and species was then assessed. This field survey contributed to the Marine Nature Conservation Review of Great Britain which commenced in 1987.
