Abstract There is increasing demand for standardised, easy-to-use metrics to assess progress towards achieving biodiversity targets and the effectiveness of ecological compensation schemes. Biodiversity based on combining habitat area condition scores are proliferating rapidly, but there limited evidence how they relate outcomes. Here, we test relationship between statutory metric used Net Gain (BNG) in England — as basis new credit systems around world invertebrate richness, abundance, community composition. We find that combined area-condition BNG does not capture value arable farmland grassland sites biodiversity: communities were highly variable across had same type under metric. was no significant abundance or species richness scores. Our results highlight need incorporate factors beyond into site evaluations, complement use with species-based surveys.
