Sažetak

Tuškanac Forest Park has been floristically studied over the past 15 years, but most extensively and systematically during the year 2021. Tuškanac Forest Park is a natural treasure in the center of Zagreb City. This oblong 150-year-old stand of oak, common beech, and hornbeam is a natural extension of the vegetation of Mount Medvednica and descends almost to Zagreb's main street (Ilica). A total of 173 vascular plant taxa were recorded (62 families and 131 genera). The largest part of the flora consists of Angiospermae (163 taxa; 94.2 %), followed by Monilophyta (6 taxa; 3.5%) and Gymnospermae (4 taxa; 2.3%). Rosaceae is the richest family with 14 taxa (8.1%), followed by Asteraceae sensu lato (13 taxa; 7.5%), Poaceae (11 taxa; 6.4%), Lamiaceae (9 taxa; 5.2%) and Fabaceae (8 taxa; 4.6%). The highest percentage of recorded plants are hemicryptophytes (41.0%) and phanerophytes (27.7%). The analysis of chorotypes shows that the Eurasian floral elements dominate (50.9%), followed by European (18.5%) and Mediterranean elements (8.1%). Urbanophobic (45.3%) significantly outnumber urbanophilic taxa (8.7%). A “close to nature“ environmental condition is additionally confirmed by the low values calculated for indicators of anthropogenisation and by the low share of alien flora (27 taxa; 15.6%). The following invasive alien taxa grow in the study site: Ailanthus altissima, Duchesnea indica, Erigeron annuus, Parthenocissus quinquefolia, Phytolacca americana, Robinia pseudoacacia and Veronica persica. According to IUCN categories, only two taxa belong to threatened categories: Taxus baccata and Lilium martagon are vulnerable (VU) and both taxa are strictly protected in Croatia.
