New paper out on how data analysis choices influence multiple stressor assessments. We used the #KGM dataset evaluated to which extent the criticism of the Liess et al. 2021 paper is relevant. We found that for most choices pesticides remain the most important driver of sensitive species loss.

Implementation of the EU Nature Restoration Regulation requires a shift from restoration targets to restoration landscapes
Nature Reviews Biodiversity, Published online: 10 July 2026; doi:10.1038/s44358-026-00186-6The EU’s Nature Restoration Regulation has created unprecedented momentum for ecosystem restoration. Its success now depends on translating ambitious targets into spatially coordinated restoration landscapes supported by effective governance, long-term financing and broad societal engagement.

We observed consistent relation with salinity, oxygen depletion, and fine sediment accumulation, while the relation with nutrient enrichment and warming varied among groups. The results allow us, amongst others, to predict how species richness changes with increasing stressors intensity (Fig. 3):

The figure (1a) shows the probability distribution on how species number of the different organism groups are associated with increasing stress intensity. Invertebrates are generally most sensitive and species number is negatively associated to six of the stressors.
