What This Reference Covers
Thistlegate documents Cirsium, Carduus, and Onopordum species recorded from Italian grasslands, roadsides, montane meadows, and coastal habitats. The three genera collectively constitute Italy's thistle flora as broadly defined — a group of approximately 45 taxa ranging from ubiquitous weedy biennials to narrow regional endemics confined to a handful of localities.
Content is structured around three primary topics: species identification (morphological keys, habitat descriptions, distribution notes), pollinator ecology (visitor records, floral resource data), and conservation status (threat assessments, habitat pressure analysis, protected area coverage). Secondary material includes phenology data, field identification challenges, and annotated reference lists.
Editorial Approach
Identification keys and distribution notes draw on herbarium collections at the Florence (FI), Rome (RO), and Padua (PAD) herbaria, supplemented by GBIF occurrence records filtered for Italy and by published regional floras. Conservation assessments follow IUCN Red List criteria (version 3.1) and the Italian National Red List for vascular plants (2020 edition). Where regional assessments diverge from national figures, both are noted.
