GES description D2 Non-indigenous species
GES description D2C1 Newly-introduced NIS
The number of non-indigenous species which are newly introduced via human activity into the wild, per assessment period (6 years), measured from the reference year as reported for the initial asessment under Article 8(1) of Directive 2008/56/EC, is minimised and where possible reduced to zero.
The threshold for good status in the Bulgarian Black Sea are as follows:
BLK-BG-D2C1_NewNIS (coastal waters) = 1
BLK-BG-D2C1_NewNIS (shelf) = 0
BLK-BG-D2C1_NewNIS (open sea) = 0
The number of non-indigenous species which are newly introduced via human activity into the wild, per assessment period (6 years), is minimised and where possible reduced to zero. The number of non-indigenous species does not exceed the threshold value.
GES description D2C2 Established NIS (2.1, 2.1.1)
Abundance and spatial distribution of established non-indigenous species, particularly of invasive species, contributing significantly to adverse effects on particular species groups or broad habitat types.
Thresholds for good status in the Bulgarian Black Sea are as follows:
BLK-BG-D2C2_ML_BIOM < 4 г/м3
Established Non-indigenous species (Mnemiopsis leidyi) introduced by human activities are at levels that do not adversely alter the ecosystems and do not exceed the threshold values.
GES description D2C3 Adverse effects of NIS (2.2, 2.2.1, 2.2.2)
Proportion of the species group or spatial extent of the broad habitat type which is adversely altered due to non-indigenous species, particularly invasive non-indigenous species. In the Bulgarian Black Sea a threshold is defined for the proportion of bivalves to invasive predatore Rapana venosa biomass:
BLK-BG-D2C3_BV/RV_RATIO ≥ 10
The impact of the established non-indigenous species calculated as Biopollution index of Mnemiopsis leidyi does not exceed the threshold value.
