Calculation of biodiversity level between different land-uses to improve conservation outcomes of biodiversity offsetting

The goal of the mitigation hierarchy is to counteract losses biodiversity due development projects by avoiding, reducing and as a last resort, offsetting these losses. However, implementation offset measures currently very unsatisfactory from perspective, many do not incorporate them. Here, we proposed method for comparing level between different land-uses propose set alternative offering same outcomes. Biodiversity (including both bird bat communities) was calculated variation in each (fallow, grass strip, bush, strip with bushes, hedgerow) compared crops (control). In order account local specificities environmental assessment studies, modulated calculation following three examples scenarios that differed according weights assigned species. For scenario, hedgerow always land-use generated greatest level, found be best terms effect size. advantage this its weighting system opinions stakeholders species, such their sensibility project or conservation status, can taken into account, resulting results being better appropriated. Thus, could implemented more efficiently thanks multi-taxonomic calculations weighing possibilities, improving This also used compare residual loss gains measures, using metric.
