Summary

This habitat occurs in the Baltic on aphotic bottoms with 10- 90% coverage of hard (rock/boulders/stone) and 10-90% soft substrata (e.g. muddy/coarse sediment/sand) according to the HELCOM HUB classification.

Threat status

Synthesis of Red List assessment

There is insufficient information on habitat extent, quality and changes over time to assess this habitat at the present time. It has therefore been assessed as Data Deficient for both the EU 28 and EU 28+.

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 This habitat is present in all the Baltic sub-basins however there is insufficient information for accurate calculation of EOO and AOO.
EU28+ Unknown Unknown This habitat is widespread however there is insufficient quantitative data to make an accurate estimate of 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).
