Study of fauna baseline survey in the area affected by facilities of planned HPP Janjići and Environmental and Social Impact Assessment study (ESIA)

Project name: Study of fauna baseline survey in the area affected by facilities of planned HPP Janjići and Environmental and Social Impact Assessment study (ESIA)

Client: JP Elektroprivreda BiH JSC. – Sarajevo
Period: 07/2014 – 06/2016
Funding: KfW
Location: Bosnia and Herzegovina


The Fauna Baseline Survey was conducted to provide information on the significance and number of species present in the area affected by the projected construction of Hydro Power Plant (HPP) Janjići on the River Bosnia. Also, it was conducted to serve as an input for the ESIA and the basis for future environmental monitoring. Habitat (including protected flora mapping) and the following fauna groups were mapped: fish, macrozoobentos, amphibians, reptiles, birds and otters.

Overall, the following activities were conducted:  mapping of fauna habitats for identified species in the coverage of hydro accumulation and excavation of a river bed and future temporary depot of excavated material, baseline survey of macrozoobenthos and ecological quality of water assessment in accordance with B&H legislation and Water Frame Directive (AQUEM), Assessment of displacement of fauna (including barrier effects) due to loss of habitat and avoiding the HPP facilities and immediate surrounding area under the impact of construction works and operation of hydro power plant was conducted. Data was organized in GIS and maps were prepared.

In the Environmental and Social impact assessment study (ESIA) the environmental components that could be affected by the project (population, noise, air quality, flora, habitats, fauna, protected areas, proposed Natura 2000 areas, landscape, geological, hydrogeological and tectonic characteristics, water, climate, existing material assets, including cultural, historical and archaeological heritage) were described. Identification, prediction and evaluation of the potentially significant effects of the HPP Janjići on the environmental components and society was conducted (social impact, impact on flora, fauna, habitats, ecological network, water, soil, climate factors, material assets, cultural and archaeological heritage, landscape). In addition, cumulative impacts were analyzed. Accordingly, the measures to mitigate negative impacts (effects) on the environment were prescribed and the Monitoring plan was presented. A public hearing for the final Study was organized.
