Species point records from 1990 MNCR Rhos Point to New Brighton littoral survey

The coastline within the survey area is bordered by the heavily industrialised Mersey to the east and the more unspoilt North Wales coast to the west. The shores within the survey area are backed by sand dunes, shore defence works and urban developments. Sediment shores predominate and there are few sites where a rocky substratum extends down onto the lower shore. Sixteen sites were surveyed on both rocky and sedimentary substrata. A wide range of soft sediment habitat was present and four basic communities were recognised: Crustacean/Polychaete, Tellina (characterised by Spio martinensis), Arenicola and Echinocardium - siliqua (with Lanice conchilega being an important component species). There was a limited range of habitats from the hard substrata sites which, together with the isolated nature of the sites within the region and the heavy sediment influence in most habitats, has lead to a poor species diversity. Beware ! the infauna has been entered in the epifauna window The nature conservation importance of the area has been assessed pointing out those sites and species which might be considered of regional and national importance.

调查区域的海岸线东临繁华的默西河，西接较为原始的北威尔士海岸。调查区域内的海岸线由沙丘、海岸防御工事和城市发展所环绕。沉积岸为主，仅有少数地点岩石底层延伸至较低的海岸。共对十六处既位于岩石底层又位于沉积底层的地点进行了调查。存在广泛的软沉积物生境，并识别出四种基本群落：甲壳类/环节动物群落、Tellina群落（以Spio martinensis为特征）、Arenicola群落和Echinocardium - siliqua群落（Lanice conchilega为其重要组成部分）。硬底质地点的生境范围有限，加上该区域内地点的孤立性以及大多数生境中重沉积物的影响，导致物种多样性较差。请注意！底栖动物数据已被录入表层动物窗口。该区域对自然保护的重要性已得到评估，指出了那些可能具有区域和国家重要性的地点和物种。
