Sublittoral Survey of Sarn Badrig, Sarn-y-Bwch and Cynfelin Patches 1986
The results of a sublittoral survey of the mid Wales sarnau (reefs) carried out in 1986 to more fully describe the sublittoral communities, habitats and species present on Sarn Badrig and the two smaller reefs to the south. The purpose of this dataset was to describe the sublittoral and sublittoral fringe communities on and around the mid-Wales sarnau (reefs), and to assess their scientific interest and nature conservation importance.

Twenty sites (15 on Sarn Badrig, 3 on Sarn-y-Bwch and 2 on Cynfelin Patches) were selected to cover a range of depths. At each site, records were made of plants and animals present at each habitat encountered. Abundance scales were used to estimate the abundances of plant and animal species and all the information was later transferred to habitat forms and species checklists. Samples of pebbles and cobbles were collected for later identification of encrusting and cryptic species and a suction sampler was used at several sites to collect sediment infauna for later identification, using a quadrat of 0.075m2 and 10cm deep to collect replicate samples at each site. Photographs of habitats and species present were taken at most sites.
