Drained by humans, rewetted by beavers—opposing forces shape boreal wetlands

A study conducted in the Evo area of southern Finland reveals how human activities, specifically forestry drainage, and natural processes, such as beaver-induced flooding, have significantly altered boreal wetlands over the past six decades. Researchers analyzed historical maps, aerial imagery, geospatial data, and field observations to show that the ditch network nearly quadrupled in size, increasing the proportion of drained peatlands from 23.8% to 72.5%. Meanwhile, beavers have created a wetland mosaic of approximately 1.4 square kilometers, restoring some wetter conditions locally. The study highlights that while drainage has had a broader impact, beavers can naturally reestablish wetlands without costly interventions. The research suggests that beaver ponds may help mitigate extreme weather events by acting as natural water reservoirs.

Bias read (Center): The article presents a balanced scientific analysis of environmental changes driven by both human and natural factors. It does not take a clear ideological stance but rather reports on ecological impacts and potential solutions. The framing remains neutral, focusing on empirical findings and expert-
