Abstract
Štirovača je dolina smještena u južnom dijelu Nacionalnog parka Sjeverni Velebit. Među rijetkim je lokalitetima Parka s izvorom pitke vode i potočićima koji znatno vlaže okolne livade. Danas su livade najugroženiji tip staništa u Parku te im prijeti nestanak. Kako bi utvrdili biološku vrijednost Štirovače provedeno je istraživanje samonikle vaskularne flore koje je dalo uvid u brojnost i raznolikost vrsta ovih livada. Na livadama Štirovače utvrđene su 134 biljne vrste s podvrstama, a najzastupljenije su svojte porodica Asteraceae i Poaceae. U inventariziranoj flori prevladavaju hemikriptofiti te svojte europsko-azijskog flornog elementa. Zabilježeno je pet strogo zaštićenih biljnih vrsta od kojih i jedan endem. Sedam svojti nalazi se u nekoj od kategorija ugroženosti. Ustanovljene su dvije alohtone vrste u kategoriji invazivnih neofita. Rezultati ovog istraživanja ukazuju na izričitu bioraznolikost vrsta livada Štirovače s naglaskom na vrijednost vlažnih livada za prirodnu i kulturnu baštinu Hrvatske.Štirovača is a valley located in the southern part of the Northern Velebit National Park. It’s one of the few sites in the Park with natural spring and water streams that significantly moisten the surrounding grasslands. Today, grasslands are the most endangered type of habitat in the Park and are threatened with extinction. In order to determine the biological value of Štirovača, a study of wild vascular flora was conducted which gave insight into the abundance and diversity of species in these grasslands. 134 plant species with subspecies have been identified in the Štirovača grasslands, with the most common species being the Asteraceae and Poaceae families. Vascular flora is dominated by hemicryptophytes and taxa of the Euro-Asian floral element. Five strictly protected plant species were recorded, including one endemic. Seven plant taxa are considered threatened. Two alien species have been identified in the invasive neophyte category. The results of this study indicate the explicit biodiversity of Štirovača grassland species, with an emphasis on the value of wet grasslands for Croatia's natural and cultural heritage
