Inventarisation of invasive flora of the city of Velika Gorica

Invazivne vrste u urbanim sredinama stvaraju mnogobrojne direktne i indirektne štete. Invazivna flora nije sustavno istraživana ni na području Republike Hrvatske, pa tako ni na području grada Velike Gorice. U ovom radu prikazana je zastupljenost invazivnih vrsta na području grada Velike Gorice i njene okolice. Nakon provedenih terenskih istraživanja, uslijedilo je sakupljanje, fotodokumentiranje, determiniranje i herbariziranje inventariziranih vrsta. Pomoću zabilježenih GPS koordinata napravljene su topografske karte. Utvrđeno je 18 invazivnih vrsta iz 14 porodica. Prema broju nalaza najbronija vrsta je Erigeron annuus (L.) Pers., a najbrojnija porodica Asteraceae. Na temelju literaturnih podataka i običaja istraživanog kraja utvrđeno je da se inventarizirane vrste koriste u prehrambene, ljekovite, medonosne, ukrasne i krmne svrhe, u različitim industrijama ili da posjeduju svojstvo alelopatije.Invasive species in urban areas create numerous direct and indirect damages. Invasive flora has not been systematically studied either on the territory of the Republic of Croatia, nor in the area of the town of Velika Gorica. This paper brings the representation of invasive species in the town of Velika Gorica and its surroundings. After conducting the field research, collection of invasive species, photo documentation, determination and herbarization of inventoried species followed. Topographic maps were made using the recorded GPS coordinates. 18 invasive species from 14 families were identified. According to the number of findings, the most numerous species is the Erigeron annuus (L.) Pers. and the most numerous family is the Asteraceae. Based on the literature and practices of the investigated area, it was determined that the inventoried species are used for food, medicinal, honey, ornamental and herbage purposes, as well as in various industries, also they possess the property of allelopathy
