How a massive annual flood creates a hidden wildlife paradise
In short: Every year, a flood wave from the Alps creates a unique ecosystem in Croatia. This video explores how the River Sava's natural flow preserves a rare, species-rich meadow landscape that thrives on seasonal cycles.
Following the annual snowmelt, a flood wave travels from the Alps toward Zagreb and Belgrade, raising the River Sava's water levels by approximately ten meters. This massive influx of water covers an area comparable to Lake Constance, creating a natural retention reservoir. Because the river flows unhindered, it protects the surrounding capitals from disaster while nourishing a rare alluvial flood plain.
This landscape represents the last major meadow environment of its kind in Central Europe. It functions as a riotous paradise where nature takes precedence over profit, supporting a diverse food web: enormous predatory catfish lie in wait for prey, birds hunt the fish, and horses bathe in the waters.
