State of the soft-bottom macrofauna community HOLAS 3
Description
The indicator evaluates the status of the soft-bottom macrofauna community above the permanent halocline in the open sea areas of the Baltic Sea. Quantitative thresholds are used to classify the core indicators status in Achieve, Fail or Not assessed. The current assessment result shows good status in most of the evaluated assessment units. The indicator is not used in coastal areas which are assessed by national methods or in areas below the halocline which are assessed using the Oxygen debt indicator. The indicator takes into account the relative proportion of sensitive and tolerant species, as well as species richness and abundance.
This dataset displays the result of the indicator in HELCOM Assessment Scale 3 (Division of the Baltic Sea into 17 sub-basins and further division into coastal and off-shore areas), so that the indicator is only applicable in the open sea assessment units.
