SUGGESTIONS FOR IMPROVEMENT Include data from the 2006 Corine land cover update when available. This would provide the 3 measurements in time proposed by CBD. Extension to pan-Europe. Develop and test complementary indicators on the changes in spatial patterns of selected ecosystems and on the changes in ecologically scaled fragmentation of habitats with regard to species. See above under 'Analysis of options'. To further improve the indicator, variance could be used together with mean values, as well as extreme values, and polygons could be grouped by size, to provide information on the data quality. Size distribution of the habitat fragments could also be investigated, in order to evaluate patch viability. Finally, a variable informing about coverage of semi-natural areas which have decreased by a certain percentage, for example 70 %, would show unequivocally an important biodiversity lost.
