The wild vascular flora of the area in the northwestern part of Croatia-Hrvatsko zagorje (near the settlements of Cerje Jesenjsko, Šaša, Pašnik, Vrbno and Ježovec, along with the related hamlets) was explored during the vegetation season of 2011. So far, no floristic data have been recorded for this area, planned to be a part of the future Hrvatsko zagorje Regional Park. On the area of about 4 km 2 , 389 vascular plant species (which belong to 77 families) were noticed. The most abundant families are Fabaceae (9.3%), Poaceae (7.7%), Asteraceae (7.5%), Lamiaceae (6.2%) and Rosaceae (5.1%). The spectrum of life forms indicates the dominance of hemicryptophytes (50.4%), and the most prominent chorological type is Eurasian (55.0%). The share of urbanophobic and invasive taxa as well as the values of indicators of anthropogenic changes in the researched flora indicate that the investigated area shows semi-natural character, with weak to moderate anthropogenic pressure. Although the share of endemic, endangered and protected taxa is low, the diversity of other native plants justifies protection of the researched area at the level of a regional park.
