This NBS involved the reconstruction of two of the total of four lakes/ponds at the Iron Fountain (Železná studnička) and was one of the project sites undertaken by the Bratislava Zelenaj project. (7, 8, 10) The location served as a recreational and relaxing spot for locals and tourists. To undertake the reconstruction, the two lakes/ponds no. 3 and no. 4 had to be discharged. Upon doing so many species of fish were found, including carp, caras, catfish, rabbitfish, toothpick, lure or amur, and also bivalve molluscs and troughs. Reconstruction of water reservoirs (ponds) no. 3 and no. 4 were implemented by the City of Bratislava within the framework of the project in cooperation with the Monumental Office of the Slovak Republic and the Municipal Forests company.

Focus

Management and improved protection of rivers and other blue areas

Project objectives

The main goal of the project was the reconstruction of two of the four ponds at Iron studienke. The objectives included enhancement of the passage for new outlets so that water can flow into a pond of Vydrica as it did in the past. (8, 14, 19) Also, the maintenance of ponds at the Iron studničke are part of the pilot project titled "Bratislava is preparing for climate change" focusing on the negative externalities of global warming on urban environments and residents.

Implementation activities

The staff of Urban Forests in Bratislava began in late July 2016 year with the first water reservoir. They discharged water from it, which was done to prepare for reconstruction work on the tank and its overall revitalization. In connection with the discharge of water from the dam, they had to provide for safeguard measures concerning the protection of the areas protected animals while the constructions took place before they could be returned to their environment. This included carp, crucian carp, catfish, pike, perch, tench and grass carp and also shellfish - mussel ponds and river trough. (9, 11, 20) Work on the ponds was originally planned to end at the end of March 2017. (12) The contract was extended however due to the January frosts, for which abstained the implementation of this NBS. (13)
