Map of integrated BEAT+ assessment of Europe\u2019s benthic habitats suggests that 58 % of the total shallow water seabed area is not in good status. The respective score varied among the sea regions: 63 %, 100 %, 98 % and 44 % of the areas assessed in the Baltic, the Black Sea, the Mediterranean and the NE Atlantic. The assessed area excludes areas where the seabed is more than 2 km below the surface as data for these areas, such as from commercial fishing, are sparse.<\/SPAN><\/P>

<\/P>

The BEAT+ tool integrates data from normalised indicators to identify worst case status measures for different biodiversity components. The results are then linked to a standard gridE based Spatial Assessment Unit (SAU) which is used both for biodiversity and for pressures assessments (Andersen et al., 2014).<\/SPAN><\/P>

<\/P>

These grid-­based SAUs not only allow alignment of indicators for biodiversity and for pressures but provide a means for combining large assessment areas (e.g. for wide\u2010ranging species) with point data collected from biological surveys e.g. WFD monitoring.<\/SPAN><\/P>

<\/P>

BEAT+ tool works by calculating a Biological Quality Ratio (BQR) which is an aggregated score of indicator outcomes within a grid square. To allow objective comparison, the indicator outcomes are normalised to a scale of 0 to 1, with five status classes at equal intervals on that scale (from Bad starting at 0, Poor at 0.2, Medium at 0.4, Good at 0.6 and High at 0.8). By this means, indicators based on different biological criteria can be aggregated in a consistent way.<\/SPAN><\/P>
