Skomer Marine Conservation Zone (MCZ) - Stereo photographic monitoring of rocky reef communities
In 2015 Skomer Marine Nature Reserve changed designation to Skomer Marine Conservation Zone (MCZ). Skomer Marine Nature Reserve (MNR) was designated in 1990. Investigating rocky reef communities at Skomer MNR. Very little is known about the community dynamics on sublittoral habitats. The epibenthic communities are one of the most abundant and important features in the Reserve. In order to make decisions about the conservation status of these communities it is vital to have some understanding of how these communities change over time. Therefore the aim of the stereo photographic monitoring is to monitor how species and communities vary over time. Possible measurements include species richness / diversity, growth rates, longevity and competitive interactions over time.

Two sites at Skomer MNR (one on the north and one on the south) have been monitored photographically since 1982. Four fixed quadrats are sampled at 10, 15, 20 and 25m BCD using a stereo underwater camera set up. The images provide a consistent time series record going back 1982. In 1982 four sites at North Wall were established at 5m depth intervals between 10 and 25m below chart datum. In 1984 a series of 11 fixed position quadrats were established at Thorn Rock. A stereo camera set was used fixed onto a 50 x 40cm frame. Samples have been taken at least twice every year (May and Sept) since the start of the project.
