Résumé Pl@ntNet is a participatory platform based on artificial intelligence to facilitate plant identification and the monitoring of plant biodiversity. In this presentation, we will first look at the technology behind Pl@ntNet, as well as the innovative …

Résumé In the context of global changes affecting biodiversity worldwide, to what extent flower visitors —and not just bees— are threatened by different environmental factors needs to be evaluated. This is critical if we are to mitigate the effects of …

Résumé Several studies have now shown at different spatial scale that certain species of the wild bee fauna are in decline in Europe. In response, some European countries and the European commission are implementing action plans to mitigate negative …

Résumé Resurveys of historical vegetation plots are invaluable to document patterns of change in community composition and diversity. They are also useful to better understand impacts of multiple and interacting global-change drivers. The relevance of …

Résumé Baseline surveys are essential to assess long-term shifts in plant communities. In the early 2000s, we re-surveyed 293   sites of six   forest types in Wisconsin, USA. Data from these sites, first surveyed in the 1950s, allowed us to infer …

Résumé The Danish monitoring program NOVANA has recorded the community composition of higher plants and selected soil chemical variable in terrestrial habitats since 2004. The monitoring program was developed as a response to the EU habitat directive and …

Résumé Standardised long-term biodiversity monitoring schemes, based on repeated visits to fixed sites, offer the possibility of comparing biodiversity in space and time, while avoiding most of the biases associated with opportunistic data, particularly …

Résumé Switzerland's biodiversity is systematically surveyed by an array of programs, each designed to cover distinct facets of biodiversity across spatial scales as well as policy evaluation needs. Although each initiative has discrete aims, …

Résumé Long-term monitoring is a crucial tool for anticipating population collapse, which is particularly important in the case of priority species (rare, endangered or threatened). The 'Adopt a plant' programme was launched in 2013 as a collaborative …

Résumé Les activités physiques, aujourd'hui considérées comme faisant partie de nos loisirs, ainsi que les sports dans lesquels certains individus démontrent des capacités exceptionnelles, étaient autrefois des pratiques quotidiennes et vitales pour nos …

Résumé Volunteer-based plant monitoring in the UK has focused historically on distribution mapping, with less emphasis on the collection of data on plant communities and habitats. However, abundance monitoring for other groups of organisms is …
