This database includes the data used in paper “Studying habitat requirements in extremely small, peripheral populations: an assessment of the barred warbler Curruca nisoria in the Italian Alps”, Ecological Solutions and Evidence. Breeding barred warblers were surveyed in South Tyrol (northern Italy) between years 2019 and 2024. We then compared the environmental and topographic characteristics of 21 presence and 21 control plots (1 ha-squares) to investigate the habitat preferences of the species in an Alpine context. Land use/land cover variables were obtained by mapping them in QGIS using detailed recent aerial photographs made publicly available by the Autonomous Province of Bozen/Bolzano, while terrain slope and solar radiation were derived in QGIS from a 10 m-resolution digital elevation model (Tarquini et al. 2023).
