With the planned construction facing continuous delays, the industrious beavers stepped in, reportedly creating dams valued at approximately 1.2 million euros. According to Bohumil Fišer, head of the Brdy Protected Landscape Area, the beavers established optimal environmental conditions that contributed to revitalizing the area much faster than governmental efforts could have achieved. The beavers’ work occurred before excavation efforts officially began, although the exact timeline of their constructions remains unclear.

Local authorities had hoped to erect a barrier that would mitigate sediment and acidic water influx from nearby ponds into the Klabava River, thus safeguarding the aquatic ecosystem. The unexpected assistance from nature highlights both the limitations of bureaucratic processes in environmental projects and the ability of wildlife to restore habitats when human intervention is temporarily stalled.
