Project summary

Edit project overview to modify the project summary.

Restoration of natural habitats alongside the rivers Vuka and Drava with the aim of restoring the original hydrological situation and providing proper habitat for protected and rare aquatic species – the interventions into the environment will also induce the forming of a new water ecosystem on Laslovo oxbow that will develop the landscape in rural surroundings and restore its ecology, forming a more sustainable and valuable natural environment and attractive ecotourism destination on the Vuka in the long run.
