Vascular flora of the educational trail "Okićnica" in The Žumberak-Samoborsko Gorje Nature Park (NW Croatia).
Vascular flora of the 2.5 km long circular Okićnica educational trail in Žumberak-Samoborsko gorje Nature Park contains 287 species and subspecies, with Fabaceae, Asteraceae and Rosaceae the most abundant families. The domination of Eurasiatic and Central European floral elements reflects the phyto-geographical position of the area; however, the presence of Illyricoid plants of mesophylous forests on the NW border of Dinarides is what makes the flora unique. The most common life forms (hemicryptophytes, phanerophytes and geophytes) are the result of a moderate climate and the dominant forest vegetation. Six vulnerable, five near threatened, ten strictly protected, two endemic and nine invasive taxa were recorded along the trail. Our results contribute to the knowledge on the flora of the Nature Park and can be used in the future design of an educational botanical trail.
