Floristic checklists carried out in Protected Areas represent important tools for flora management. A checklist of Turvo State Park’s vascular flora was created based on a floristic survey published on 1985 and using the available databases and own collections. Biological form, habitat, category of threat and rarity of the species were indicated. Rheophytic species were listed and categorized. A total of 892 species were recorded, being 800 angiosperms and 92 ferns and lycophytes, representing an increase of 22,7% in relation to the previous list. The richest families were Asteraceae (62 species), Poaceae (57) and Fabaceae (53), making up 19% of the total. Herbs (40%) were the most representative biological form, followed by climbers (18%), trees (17%), epiphytes and subshrubs (8% each), shrubs (7%) and other forms (2%). There are 42 rheophytes, 13 of which are exclusive, 9 are preferential and 20 are occasional. A total of 51 species are threatened with extinction, being 24 in the Vulnerable category, 16 Endangered and 11 Critically Endangered. Thirty-tree species of restricted occurrence to the Alto Uruguai region in Rio Grande do Sul state were highlighted. The present results demonstrate the need for updating floristic lists as one of the basic tools for biodiversity conservation.
