Summary

Circalittoral rock starts at the lower limit of distribution of photophilic algae (which may be as shallow a 10 m on the north-western Black Sea shelf and much deeper in Crimea or Turkey) and ends where the circalittoral rocky substrate gives way to sediments. This habitat is characterised by a complete lack of algal and faunal species.

Indicators of quality:

There are no commonly agreed indicators of quality for this habitat.

Distribution

For each habitat a distribution map was produced from a wide variety of sources indicating known and potential occurrences of the habitat in 10x10 km grids within Europe. Occurrences in grid cells were given in two classes: actual distribution from relatively reliable sources (surveys, expert knowledge), and potential distribution based on models or less reliable indicators. Please download the fact sheet to see the map.

Extent of Occurrence, Area of Occupancy and habitat area

Extent of Occurrence (EOO) (Km2) Area of Occupancy (AOO) Current estimated Total Area Comment
EU28 Unknown Unknown Unknown The habitat is known to occur in the Black Sea but there is insufficient data to accurately calculate EOO and AOO.
EU28+ Unknown Unknown The habitat is known to occur in the Black Sea but there is insufficient data to accurately calculate EOO and AOO.
AOO = the area occupied by a habitat measured in number of 10x10 km grid cells.
EOO = the area (km2) of the envelope around all occurrences of a habitat (calculated by a minimum convex polygon).
