Several dead reindeer carcasses were discovered on the Puutosuo mire in North Ostrobothnia following a heatwave, and water samples showed tenfold elevated intestinal bacterial levels, suggesting possible poisoning or bacterial contamination.

In Karasjok this spring, bears, lynx and a golden eagle attacked an enclosed reindeer herd, killing around 100 animals, while five state agencies coordinated the response and initially denied a permit for lethal control.
