Contributo alla conoscenza della flora del Comune di San Miniato

This study presents an updated contribution to the knowledge of the vascular flora of the municipality of San Miniato (Tuscany, central Italy), an area characterized by a mosaic of alluvial plains, hilly systems, and agriculturally transformed landscapes. Over the past two decades, floristic data were gathered through opportunistic observations, later integrated with literature records and the Wiki-Plantbase #Toscana database. The resulting checklist includes 757 species belonging to 103 families and 439 genera, of which 130 are alien taxa. Analyses of biological forms, chorotypes, Ellenberg ecological indices, reproductive traits, and phenology reveal a flora reflecting the transitional Mediterranean–temperate setting of the area. The data highlight the ecological imprint of land-use change, the increasing prominence of synanthropic and exotic species, and the persistence of rare hygrophilous taxa of conservation interest. The study provides a foundational reference for future ecological assessments, management planning, and conservation strategies within this culturally and environmentally complex landscape.
