This document summarizes research on monitoring biodiversity in urban forests in Lombardy, Italy. Birds and insects were used as indicators of biodiversity. Over 20 species of birds were recorded during point counts in forests. Butterfly and beetle species were also recorded at forest sites. Analysis found links between biodiversity and forest structure, with more species found in areas with greater tree diversity, coverage, and distance from city centers. Specific bird species like the blue tit were examined in relation to diameter at breast height statistics of forest trees. The research aims to inform management decisions about maintaining and enhancing biodiversity in urban forests.
