The insect crisis, as conservation topic, has historically received little attention among the general public. Yet, the publication “More than 75% decline over 27 years in total flying insect biomass in protected areas” by Hallmann et al. gained vast media coverage in Germany in October 2017. Given the media's known influence on public perception, we investigated (i) whether coverage of this publication increased awareness among the German public for insect die‐off, and (ii) whether it contributed to people's intentions to undertake insect protecting actions. We used Google Trends to examine people's internet activity in Germany in relation to keywords relevant to our research question. A high peak in Google searches for insect die‐off (“Insektensterben”) was indeed visible immediately after the study publication, and search volume remained significantly higher for the following 6 months, confirming that the topic gained attention. Further, searches for the three keywords insect hotel , bee‐friendly and bee meadow (“Insektenhotel”, “bienenfreundlich”, “Bienenweide”) increased significantly over the summers of the years 2017 to 2019. It appears that increased media attention around insect die‐off spurned by the publication of Hallmann et al not only addressed the crisis but also encouraged implementation of simple insect protection measures by the public. These findings suggest that cooperation between the media, conservation organizations and scientists to disseminate evidence‐based information alongside practical conservation measures may have lasting benefits.

Managing non‐native species in cities is often controversial because these species can support both ecosystem services and disservices. Yet, how the acceptability of non‐native species management by the general public differs in relation to native species, to distance (i.e. close to residence and elsewhere) and among plants and animals is understudied. Furthermore, while values, beliefs and knowledge are often considered in this context, psychometric factors such as emotions and anthropomorphic views have received little attention. We surveyed 658 residents in Berlin, Germany, to assess (i) the acceptability of management actions differing in their severity for non‐native plants and animals compared to native species with similar traits, (ii) the influence of perceived distance of species (i.e. close to residence and elsewhere) and (iii) the predictive potential of psychometric (i.e. values, beliefs, self‐assessed knowledge, emotions and anthropomorphism) and socio‐demographic factors for this acceptability. Eradication (i.e. lethal control/removal) was generally the least accepted management action, but more accepted for non‐native than native species. Distance mattered for the acceptability of non‐native plant management with unspecified control action the most accepted management action close to residence. While values (self‐transcendence and conservation) mostly explained the acceptability of doing nothing and eradication, emotions related strongly to all management actions. Beliefs were more important than self‐assessed knowledge in relation to non‐native species management and beliefs about non‐native plants and animals were rated almost similar. Anthropomorphic views had predictive potential for plants and animals; that is, the stronger people held anthropomorphic views, the less they accepted eradication. Participants with a garden supported doing nothing with plants (native and non‐native) more than without. Results highlight the complexity of factors underlying the acceptability of management actions on species in cities. While values, beliefs and self‐assessed knowledge are important in the context of species management, other psychometric factors add to our understanding of acceptability. We conclude that awareness about different acceptability patterns related to species management can support environmental policies on biological invasions in cities. Tailoring and implementing adequate management actions can benefit from incorporating cognitive but also affective factors of the public.
