Based on the evaluation of 3,902 local floristic references published between 2005 and 2025, an update to the floristic knowledge map of Italy is presented. To measure the progress in floristic knowledge across Italy’s administrative regions, the ‘Index of Floristic Knowledge Advancement’ (IFA) is proposed here. This index categorizes regions based on the proportion of potential improvement that has actually been achieved. Res...

Floristic mapping advances the biogeographical knowledge by revealing patterns of biodiversity through a standardized grid-based survey of species’ occurrences. It consists of the systematic grid-based survey of species occurrence, aimed at producing distribution maps of vascular plants within a given territory. We compiled a dataset of 32,939 floristic records (field observations, herbarium specimens, and literature) referenc...

The Convention on Biological Diversity ( CBD ) aims at the conservation of all three levels of biodiversity, that is, ecosystems, species and genes. Genetic diversity represents evolutionary potential and is important for ecosystem functioning. Unfortunately, genetic diversity in natural populations is hardly considered in conservation strategies because it is difficult to measure and has been hypothesised to co‐vary with spec...
