Sadly the seal died over the night of Friday-Saturday.
It had been moved to the wildlife hospital while the temporary enclosure was renovated. This was because its skin had been damaged on the rough surfaces of the pool.
Examinations suggested there might be further issues and it was discovered the seal had been eating sand and hay. Treatment followed with improvements in its condition but unfortunately it later died of complications related to this.
Korkeasaari have started a collection to support the conservation of Saimaa ringed seals in the wild. Low snowfall this winter is having a negative impact on the seals as they build dens in the snow.
To quote WWF:
Climate change poses a threat to Saimaa ringed seals. They need snow to build the lairs where they give birth. These lairs protect their offspring from the cold, predators, and human disturbance. But over the past several years, the snow cover in the region has not been deep enough to create those lairs.
Humans are helping the extremely endangered Saimaa ringed seals in their struggle to find suitable places to nest by piling up snow on lake Saimaa’s ice to form man-made snow banks for nesting. In 2017, out of the 81 pups born, 90 percent were born in the man-made banks.
