Habitat point records from 1986 Portsmouth Polytechnic Kench (Langstone Harbour) survey

This study of the macrofauna of The Kench, a small embayment in the Hayling Island shore of Hayling Island, Hampshire, was commissioned by the Nature Conservancy Council in order to provide information on the macrofauna with special regard to invertebrate species of importance as prey items to the avifauna. Small cores were used to capture the smaller animals and large cores for the larger animals. Only three sites were chosen and extensively sampled to ensure a successful catch. The sites were chosen to represent (1) an upper shore feeding ground, (2) a mid shore feeding ground and (3) a low shore site. The sites reflected algal cover variations since they were , respectively: Enteromorpha covered, Ulva covered and bare mud areas. At each site eight cores were taken using plastic drainpipe and placed in polythene bags. Half these cores were 0.0177m^2 area and 0.2 m deep and the other half were 0.0053m^2 by 0.015 m giving a total sampled area of 0.092 m^2. Large cores were put through a 2 mm sieve and small cores through a 0.5 mm sieve.
