Species point records from 1990 Collins/Mallinson Kimmeridge sublittoral survey

The date of this survey is not available in the report. In 1988, a permanent underwater nature trail was installed off Worbarrow Tout, Dorset, within the Purbeck Marine Nature Reserve. This consists of a fixed 150 m line extending from surface rocks, between gullies, down a boulder slope, across stoney gravel, to a low-lying rock pile in 15 m of water. A second 'hidden' trail was also set up to the east with the aim of comparative studies to determine the effect of intensive diver pressure. The details of this work is described in a previous report to the NCC, which also describes the general marine flora and fauna of the trails and adjacent areas. The numbered stations along the trails were originally intended to provide convenient points for description in diver guides. However, their permanence makes them ideal long-term monitoring stations. This study aimed to give a detailed description of each of the 9 stations along the primary trail. This includes habitat descriptions, species lists and diagrams. Additionally a set of slides for each station has been prepared with wide angle views (2 m across), closer views (60 cm across) and detailed shots (24 cm across). Underwater video footage has also been recorded and used in preparing the description of the stations.
