Our moral circles—that is, the entities believed as worthy of moral concern and thus deserving moral considerations—have historically expanded beyond humans to include also nonhuman beings (Crimston et al., 2018). As a result, various emerging legal instruments around the world have been granting rights to animals. However, the inclusion of animals within moral circles is subjected to important biases, with a preference for charismatic, familiar, and beautiful vertebrates (Klebl et al., 2021). We argue that legal instruments embracing such biases may jeopardize biodiversity conservation., The authors would like to thank all researchers who have kindly contributed to the discussion of this conservation problem in Spain.

In autumn 2021, the largest volcanic eruption on the island of La Palma in historic records took place. The Canary Islands are of volcanic origin and eruptions have always constituted part of their natural disturbance regime. Until recently, their impacts could not be directly observed and studied. Influence of the emission of phytotoxic gases on biodiversity and ecosystem dynamics was hitherto unknown. The recent eruption is still being intensely monitored. We used Sentinel-2 remote sensing data to analyze the spatial extent and intensity of the impact related to sulfuric emissions, aiming to understand the damage patterns in Canary pine forest. The emissions damaged 10% of that forest and affected 5.3% of the Natura 2000 protected areas. We concluded that this is largely due to the toxic effects of the enormous emissions of SO2. We found a clear correlation between the change in the normalized difference vegetation index (NDVI) and distance from the eruption. This pattern was weakly anisotropic, with stronger damage in southern directions. Counteracting effects, such as ash deposition, were largely excluded by combining NDVI change detection with tree cover density. We expect that vegetation damage will be transient. P. canariensis can resprout after forest fires, where most leaves are lost. Consequently, our assessment can serve as a reference for future ecosystem regeneration., This research was funded by the EU Horizon 2020 project e-shape under the grant agreement 820852.
