Efforts to mitigate the negative effects of human activity on small peri-urban watercourses have long been inadequate compared to other ecosystems, despite the fact that they provide numerous ecosystem services. Although they have been better accounted for since the publication of the Water Framework Directive, they receive less investment. One of the reasons may be that aquatic biodiversity fails to capture the attention of the general public, whose support is essential for promoting the conservation of these environments. Our objective is to shed light on the hidden aquatic biodiversity through terrestrial species in small streams in the Île-de-France region. With the emergence of citizen science, it is now easier to determine which taxa are most appreciated by the public and access the data collected through these initiatives. Using a species distribution model, we estimated the distribution of four terrestrial taxa: odonates, lepidopterans, common pipistrelles, and Anatidae, which are frequently observed in Île-de-France with a minimum of 2500 observations between 2007 and 2017. This distribution was then compared to the distribution of aquatic biodiversity data related to benthic macroinvertebrates from regulatory monitoring networks at 106 stations during the same period. According to our results, with just these four taxa, we managed to have representatives for all types of benthic macroinvertebrate communities, whether in degraded or non-degraded situations.
