Overall assessment: GES is achieved if the proportion of habitats in good status from all representative habitats in the MRU is 100 % - all habitat shall be in good status. One habitat is allowable to be in not good status on the condition that no more than 20 % of its total natural extent at national level is adversely affected and no more than 20 % of the total seabed in the MRU is adversely affected. D6C4: The extent of habitat loss resulting from anthropogenic pressures does not exceed 5 % of the total extent of the habitat type in the assessment area, relative to baseline in early 1980s. D6C5: The extent of adverse effects from anthropogenic pressures on the condition of the habitat type, including habitat loss, does not exceed 20 % of the natural extent of the habitat type in the assessment area. D6C3: The threshold value for absence of adverse effects of physical disturbance from fisheries is SAR ≤ 0.2. Swept Area Ratio - SAR D2C2: The threshold value for absence of adverse effects from the invasive species Rapana venosa is Bivalves/Rapana biomass ratio ≥ 10. D3C3: The threshold value for the size structure of the population of the commercially-exploited bivalve Donax trunculus is L95 ≥ 33.78 mm. D5C8, D7C2, D8C2, D8C4: The threshold value for adverse effects from pressures, including under criteria D5C8, D7C2, D8C2, D8C4 is EQR M-AMBI(n) ≥ 0.68 corresponding to good status.

Spatial extent and distribution of physical loss (permanent change) of the natural seabed.

Spatial extent and distribution of physical disturbance pressures on the seabed.

The spatial extent of each habitat type adversely affected by physical disturbance.

The extent of habitats subjected to physical loss.

The extent of adverse effects from anthropogenic pressures on the condition of the habitat type does not exceed a specified proportion of the natural extent of the habitat type in the assessment area.
