Macro-moth (Lepidoptera) Diversity of a Newly Shaped Ecological Corridor and the Surrounding Forest Area in the Western Italian Alps

In addition to the compilation of biodiversity inventories, checklists, especially if combined with abundance data, are important tools understand species distribution, habitat use, and community composition over time. Their importance is even higher when ecological indicator taxa considered, as in case moths. this work, we investigated macro-moth diversity a forest area (30 ha) Western Italian Alps, recently subjected intense management activities. Indeed, an corridor, which includes 10 clearings, has been shaped thanks compensation related construction site Turin–Lyon High-Speed Railway. Here, identified 17 patches (9 clearings 8 forests), conducted moth surveys using UV–LED light traps. A total 15,614 individuals belonging 442 were collected 2020 2021. Two fifteen new records for Piedmont Susa Valley, respectively. faunistic interest study—using standardized method—provides geo-referenced occurrences, species-richness, values useful compile baseline dataset future comparisons. replicable easy shareable method allows us make comparisons other research thus assess impact environmental changes.
