Integrating Ecological Connectivity into Conservation of the Last European Free-Flow-River Protected Area

Habitat fragmentation and human direct intervention in river morphology and hydrology has become one of the severe issues of fluvial ecosystems within the Balkan Peninsula. Thus, it is critical to research and protect native eel habitats. The Balkans are home to some of the few remaining large, near-natural rivers in Europe. This study presents a comprehensive, spatial assessment of freshwater components’ biogeographical patterns across the Vjosa/Aoos transboundary river between Greece and Albania with regard to ecological connectivity using newly compiled distribution data derived from appropriate modeling, covering the Albanian part of the basin. Using biodiversity data as a case study, this research aims to provide a series of recommendations that may be helpful for managers of an aquatic protected area. A novel dendritic connectedness index (DCI) has been computed for the main river channel and its tributaries, and the thorough technique utilized in this study to model species distribution using Maxent aims to identify suitable habitats for the target species. In order to provide evidence-based information for water management decisions, we connect study findings to pertinent laws and references. To ensure the Vjosa/Aoos’ exceptional conservation value, we demand its serious protection.
