Survey of amphibian breeding sites in the Vallinfreda Municipal Area: a Citizen Science contribution to wildlife conservation.

Abstract

The dataset contains original occurrence and environmental data for all known potentially suitable amphibian breeding sites within the Vallinfreda municipal area. Monitoring activities were conducted from February to August 2025 and covered 45 localities. Amphibian presence or absence was confirmed after repeated visits to each site across different seasons. This approach enabled the observation of individuals at various developmental stages, facilitating species identification without handling any animals. For each locality, the potential breeding site was confirmed when at least one amphibian species was observed at any developmental stage.
Environmental data were collected as the relative percentage of land use composition (streets,  urban areas, grazing land, shrubs, farming lands, mixed forests, reforestation, rushes and reeds) within a 100 m radius of each site. The percentage of sun exposure, and, when applicable, water body volume were also included. The project was fully funded by the Vallinfreda Pro Loco as part of a broader citizen science initiative aimed at promoting environmental education, scientific awareness, and the conservation of local biodiversity.
