The endangered Saimaa ringed seal population has reached a major milestone. For the first time, the species has surpassed 500 individuals in official population estimates. The latest count shows 530 seals living in Finland's Lake Saimaa system.
This represents growth from last year's count of 495 seals. The population estimate is conducted each January, meaning newborn pups from spring are not included in these numbers.
This spring brought 114 new seal pups into the world. A decade ago, that number stood at only about 80. Warmer winters have complicated breeding efforts, leading to high pup mortality rates.
Humans are now building artificial snowbanks on the ice to help the seals. These structures provide crucial protection during breeding season. About 85 percent of newborn pups relied on these human-made shelters this spring.
Most population growth occurs in Puruvesi and Greater Saimaa areas. The situation appears much weaker in Northern Saimaa, according to conservation experts.
Northern Saimaa shows concerning conditions, particularly around the Pyhäselkä-Jänisselkä area. No seal pups have been born there for three years. The nearby Orivesi area records just one pup annually.
This year, 45 dead Saimaa seals have been found. Half died as pups in their nesting areas, while eight perished in fishing gear, mostly nets. Authorities are investigating other causes of death at the Finnish Food Authority.
Current fishing restrictions in Lake Saimaa are being updated. Citizens can share their views through a public consultation process.
The population growth shows conservation efforts are working, but climate change presents new challenges that require ongoing human intervention.
