Floristic and habitat diversity of Hrastovička gora (Petrinja City area)

Hrastovička gora najsjeverniji je dio brežuljkastog područja Zrinske gore u Banovini (Sisačko-moslavačka županija). Dosad nije napravljen sustavni popis flore Hrastovičke gore. Tokom 2020. godine provedena su terenska istraživanja flore 31 plohe na 13 stanišnih tipova na tom području kako bi se usporedila stanišna raznolikost ovog kraja. Determinirano je 418 biljnih vrsta iz 85 porodica, među kojima 15 ugroženih, 14 strogo zaštićenih, 18 invazivnih, te jedna endemska vrsta. Na temelju florističke raznolikosti te ekoloških svojstava biljnih svojti (florni elementi, životni oblici, ekološki indikatorski faktori, životna strategija, podrijetlo) provedena je usporedba grupa ploha koje pripadaju istom ili sličnom stanišnom tipu. Analizom je uočen značaj šuma kao staništa za rijetke i ugrožene biljne svojte, te termofilnih travnjaka za orhideje.Hrastovička gora is the northernmost part of the hilly area of Zrinska gora in Banovina (Sisak-Moslavina County). No sistematic research on flora of this region was ever done. Fieldwork focusing on 31 sample sites across 13 different habitat types was carried out during 2020 in order to compare different habitat types. 418 plant taxa belonging to 85 plant families were found, of which 15 taxa are endangered, 14 are strictly protected, 18 are invasive and one is an endemic species. Based on the floristic diversity of these sample sites, accompanied by ecological data on found taxa (chorological types, life forms, ecological indicator values, life strategies, origin), a comparison of sample sites was made. Forests have proved to be an important habitat type for endangered and strictly protected plant taxa, as well as thermophilous grasslands, where many Orchidaceae species were found
