The development of the Streamlining European Biodiversity Indicators 2010 (SEBI 2010) indicator set is described and critically reviewed for coverage and gaps. The indicator set is tested for historical background that would support trend analysis and found to be sensible, but the deficiency of direct biodiversity measurement rather than pressures on biodiversity is problematic.

Spiders at 23 Portuguese protected area sites were sampled (pitfall trapped) over 10-month periods. The data allowed for a “biodiversity quality” assessment consisting of the following indices: Species Richness, Biomass, Simpson Index, Species Conservation Value Index and Population Density. These “biodiversity quality” characteristics were reviewed for relative indication of site spider “biodiversity quality”.

1. Recent political agreements mandate that the current rate of biodiversity loss is reduced by 2010 (the 2010 target). In Europe one of the 26 indicators given for this assessment is butterfly biodiversity which therefore requires butterfly biodiversity to be measured. Feest et al. (2010) advocates that this can be done using the concept of “Biodiversity Quality”.
