Narrative

The project removed the dense network of drainage channels, built a system of 14 pools and restored the area's ability to retain water. After the revitalisation, the groundwater in the Libuňka river floodplain rose to its natural height, the retention capacity of the area increased by more than 26 500 m³ and the site was colonised by rare species of amphibians and birds.

Financial data

The costs amounted to CZK 3 249 271. The subsidy from the Operational Programme Environment covered CZK 3 249 271.

Recommendations

This is a recently completed project, so the improvement of the ecosystem and biodiversity can be evaluated with some distance. However, the revitalised wetland is already having a positive impact on a number of climate risks - it is playing an important role in dealing with torrential rainfall and flooding interspersed with long-term drought. The interruption of the drainage network prevents concentrated water runoff from the area. Thanks to natural evaporation, the wetland cools its surroundings on hot days and thus the landscape does not overheat. In addition, the implementation of the pools has significantly enhanced the biodiversity of the site.
