Sažetak
In present time of globalisation, transport of animal and plant alien species is increased. With their arrival to the new habitat they often show invasive character due to various reasons, e.g. lack of predators or equally competitive species. During regular monitoring of macrophytes for ecological quality assessment in June 2013, Egeria densa Planch. was identified in the Norin River at the site approx. four kilometres before confluence with the Neretva River. The following year, in 2014, E. densa was confirmed at the same locality in the Norin River but it was also found in its spring area and in Vid village, as well as in nearby Lake Modro Oko. During sampling of E. densa in 2014, basic physical and chemical parameters of water were measured, identifying slightly brackish water with higher conductivity and neutral to slightly alkaline pH. Spreading of E. densa was also noticed in the year 2016 when it was identified in the Mislina River at Mlinište village near Opuzen. This non-native plant in the Mediterranean rivers and lakes already shows its invasive character creating population of very thick masses in Lake Modro Oko and the Mislina River. Such observations indicate that it is posing a threat to the biodiversity of hundreds of rivers and canals in the Neretva River Delta. Other European countries with confirmed presence of E. densa are Austria, France, Italy, Hungary, Germany, Slovakia, Spain Switzerland, Turkey and Great Britain.
