Saimaa ringed seals are very sensitive to disturbance, and it is forbidden to deliberately approach them without a permit.
I once wrote here about one of John’s a Ukrainian employees who told me that in Soviet days it was dangerous to read certain books. People read The Master and Margarita, for example, under the library table with a flashlight if no one was around.
I don’t think we are there yet, but I do have a sense that a whole segment of our society will be living an alternate life and trying not to draw attention. That might include people who care about wildlife and global warming, like the Finns in today’s story.
Phoebe Weston writes at the Guardian, “Eight hours shoveling snow in -20C [-4 F] might not sound like the ideal day out, but a committed team of volunteers in Finland are working dawn to dusk building enormous snow drifts for one of the world’s most endangered seals.
“The Saimaa ringed seal was once common around Lake Saimaa in the south-east of the country, but only 495 of them remain.
“The seals make ‘snow caves’ inside snow drifts where they raise their young and protect them from the elements and predators such as red foxes – but as the climate warms, the snow is disappearing. To save these rare seals, 300 volunteers spend days shoveling snow into piles [23 feet long] around the edge of the frozen lake. Last winter they made 200, and the seal population is growing as a result. …
Volunteers meet at first light and work until dusk. [Vincent Biard, a PhD student and volunteer from the University of Eastern Finland] describes the day as ‘kind of fun,’ and adds, ‘you actually have an impact, which is nice. If we don’t do it, then they would just go extinct quite quickly.’ …
“Saimaa seals are less than 1.5 metres long and each one has a unique fur pattern – individual to each animal, like human fingerprints. In the late 1980s their population dwindled to its lowest point, with fewer than 200 left, driven by hunting and deaths caused by fish traps. Accidental deaths in fishing nets remain a challenge.
“Now, the seals are fully protected but the threat of the climate emergency looms large. Between 1925 and 2002, the maximum thickness of the ice decreased by 1.5cm [~i/2 inch] a decade. In mild winters the ice caves can collapse, leaving the pups exposed, with up to 30% of them dying.
“Human-made snow drifts are larger and ‘more durable than natural snow drifts,’ says [Jari Ilmonen, coordinator of Our Saimaa Seal Life, which is an EU-funded program]. …
In the future, ice cover is expected to disappear before the pupping season has ended.
“There have already been some winters where there has not been enough snow to create an artificial drift. In some cases the seals have been known to breed elsewhere, but with no snow ‘just a few would hang on,’ says Ilmonen.
“However, scientists from the University of Eastern Finland are working on plan B. They are creating artificial dens, or nest boxes, that mimic the real thing, with preliminary research showing the seals use them for resting, giving birth and nursing their young. The nest boxes could be used in ice-free winters, researchers say. …
“There are about 40 dens on the lake, where three pups have already been born, but Ilmonen wants to get more out there. ‘If you think that there are maybe 500 seals and maybe 100 pups born each year, you’d need a lot of the boxes,’ he says.
