Ice breakup on Lake Vänern after coldest winter in 13 years

Ice breakup is occurring along the shoreline of Lake Vänern in Sweden. This follows a cold winter with extensive ice coverage on the lake, which had not happened in 13 years. Martin Sandmark, a landscape conservationist focusing on the Vänern area, explains that the ice plays a crucial role by scraping vegetation off the shores, benefiting biodiversity.

He notes that many species depend on this disturbance from ice and water. The ice formations are described as mighty, and the sound of ice floes rubbing together signals the arrival of spring. Sandmark plans to check the effects of the ice's work in the Lurö archipelago once the boat melts free.
