The Saimaa ringed seal population has reached 530 individuals according to the latest count. This marks an increase from 495 seals recorded last year.
Conservation efforts show mixed results across different parts of Lake Saimaa. The population grows strongest in Puruvesi and southern Suur-Saimaa regions.
Northern Saimaa presents serious concerns for conservationists. No seal pups have been born near Joensuu in the Pyhäselkä-Jänisselkä area for three consecutive years.
This year's count revealed 114 newborn seal pups. A decade ago, the annual average was only about 80 pups.
High pup mortality remains a major challenge. Climate change increasingly creates poor breeding conditions for the endangered species.
Artificial snow banks play a crucial role in seal survival during low-snow winters. A large majority of pups now depend on these human-made structures.
Conservation specialist Riikka Alakoski from the Finnish Forest and Parks Service explained the situation. "Without artificial snow banks and nest structures, pup mortality would be even higher," she said in a statement.
Fishery equipment poses additional threats to young seals. Officials found 45 dead Saimaa seals this year, with eight confirmed deaths caused by fishing gear.
Current protection measures may become insufficient as climate conditions worsen. Artificial snow banks could melt too early or lack sufficient snow cover in future winters.
WWF program director Petteri Tolvanen noted the experimental nature of artificial nests. Replacing snow banks with artificial structures would require massive operational efforts.
The fundamental challenge remains climate change mitigation. Conservationists emphasize that controlling global warming is essential for the species' long-term survival.
While population growth offers hope, the uneven regional distribution and high pup mortality reveal the fragile nature of this conservation success. The species remains critically endangered despite recent gains.
