Site Description: A very sheltered narrow shore within the Foyle estuary just downstream of the New Bridge. Fucoids dominated low small sandstone ridges with soft silt and small boulders between. All ridges and organisms were covered with silt. A narrow saltmarsh occurred in the upper shore extending from a walled boundary of parkland (private). The estuarine nature of this habitat is illustrated by a zone of Fucus ceranoides in the upper shore. Some areas of flat broken sandstone occur with little algal life growing on it except some patches of Blidingia sp.. Four biological zones were noted. The mud between ridges tended to be only a few cms thick with a shallow sulphide layer. Hediste diversicolor (originally recorded as Nereis diversicolor) ranged from common to abundant. Access may be gained directly to the shore by walking down a patch from a small car park. Fences must be climbed through, but not difficult.
