The Kemijoki River Delta is located where Finland's longest river meets the Bothnian Bay, near the city of Kemi. This extensive estuarine area is ecologically invaluable, serving as a vital resting site for thousands of migratory birds on their way to the Arctic. The landscape is characterized by numerous low-lying islands, reed beds, and regularly flooded alluvial forests. Geologically, the delta is undergoing constant change due to post-glacial land uplift, which here occurs at a rate of about 8 to 9 millimeters per year, among the fastest in the world. Historically, the delta was a major center for salmon fishing and timber exports. Today, the region is regulated by hydroelectric dams upstream, which affects natural sedimentation processes but still sustains rich biodiversity in the remaining wetlands.
