OOAO (20 or 57.1%)
Integration rule description for parameters
Swept Area Ratio is used as indicator for assessing adverse effects under D6C3.
Multi-metric index M-AMBI(n) is used for assesing D5C8, D7C2.
Extent in square kilometers is used for habitat loss under D6C4.
Polygon shapes are created in GIS for not good status according to thresholds of SAR and M-AMBI(n) and for habitat loss and then merged to created a shape of overall adverse effects.
