New data on distribution of Apium repens (Jacq.) Lag in the Slunjčica River, Croatia

Species Apium repens grows on wet and aquatic habitats. In Croatia it is distributed mostly along karstic rivers. Field investigation was performed in the autumn of 2016 from the boat, with the purpose to record and map distribution of Natura 2000 species Apium repens along the course of the river Slunjčica. Studied aquatic habitat, with a total length of 6, 5 km, was divided into survey units. For every survey unit we estimated cover with A. repens plant stands according to Braun-Blanquet five-point-scale in each survey unit. The study determined occurrence of the species A. repens on 52 of 96 survey units in total. Estimated cover ranged from 1 to a maximum of 5 in some survey units. Distribution was not continuous. Newly gathered results are significant contribution to assessment of the status of this species in Croatia and to establishment of effective conservation management for Apium repens on the Slunjčica Natura 2000 site.
