Sažetak
Župa dubrovačka is one of the Croatian region less known from botanical point of view. In 2016, a two-years project has started with the aim to investigate flora, presence of alien plants in particular, and current status of the habitats in the area. Study area (surface area of 22.81 km² with an altitude ranging from 0- 628 m a.s.l.) is characterized by complex geomorphological features (steep hillsides, agricultural terraces on slopes, occurrence of intermittent or permanent springs, etc.) and substrata diversity. The coast (cliffs, rocky and pebble beaches) has a total length of 11.4 km. The area has 8, 300 year-round inhabitants (estimated 2011), but this number increases several-fold in summer. Until now, 20 alien plant taxa have been noted. These were: Ailanthus altissima (Mill.) Swingle, Amaranthus deflexus L., A. hybridus L., A. retroflexus L., Aster squamatus (Spreng.) Hieron., Bidens subalternans DC., Chenopodium ambrosioides L., Conyza sumatrensis (Retz.) E. Walker, Datura innoxia Mill., D. stramonium L., Euphorbia prostrata Aiton, Galinsoga parviflora Cav., Helianthus tuberosus L., Parthenocissus quinquefolia (L.) Planchon, Paspalum dilatatum Poir., P. paspalodes (Michx.) Scribn., Phytolacca americana L., Robinia pseudoacacia L., Sorghum halepense (L.) Pers. and Xanthium strumarium L. ssp. italicum (Moretti) D. Löve. The region is affected by strong anthropogenic influences, especially grazing, fire and cutting, and more recently the urbanization of the coastal zone. These features certainly contribute to the richness of alien flora.
