A floristic study of the vascular flora of ancient olive groves of Apulia (Italy) was carried out from 2009 to 2012. Research was mainly focussed on the fields and the ecological infrastructures of four olive groves. In total, 408 taxa were identified, of those, 332 species, 73 subspecies and 3 cultivated varieties were classified into 275 genera and 74 families. Only 18 taxa out of the 408 were considered important from a conservation point of view. These 18 taxa were analysed more thoroughly, the topography of the collecting site, plant community, population density and relationships with the habitats being recorded, according to Directive 92/43/EEC. The work was planned and carried out with the aim of providing tools for improving the conservation and management of the olive groves of Apulia.U razdoblju od 2009. do 2012. istraživana je vaskularna flora starih maslinika Apulije (Italija). Istraživanje se usredotočilo na polja i ekološku infrastrukturu četiri maslinika. Sveukupno je zabilježeno 408 svojti, od toga 332 vrste, 73 podvrste i 3 kultivirana varijeteta, smještenih u 275 rodova i 74 porodice. Samo 18 svojti od njih 408 se smatra važnima u smislu zaštite. Tih 18 svojti su podrobnije analizirane, i u skladu s Direktivom 92/43/EEC za njih je zabilježena topografija nalazišta, biljna zajednica, gustoća populacije i suodnos sa staništem. Istraživanje je planirano i izvedeno u cilju pronalaženja načina za poboljšanje zaštite i upravljanja maslinicima u Apuliji
