After an extremely busy and successful season on Skomer, we’ve now only got four people left on the island; Sylwia and Nathan – the new Wardens, and Bee and Ed - the old (but still very young) Wardens 😉 who will sadly be leaving the trust at the end of the year. They will be deeply missed and have done incredible things for wildlife conservation on Skomer.  The Trust is very excited to welcome Sylwia and Nathan onto our dedicated team and we can’t wait to see what they get up to.

It is definitely different on the island without daily visitors and volunteers' company. The wardens are still enjoying themselves and working hard to make sure that everything is safe, sound and secure for the next season in 2019.

 

Storms on the Islands

Unfortunately, we have been experiencing some storms on the island again this year, with wind gusts reaching 60 knots. Thank goodness we haven’t got anything like last year when Storm Ophelia and Brian hit both Skomer and Skokholm very badly. Our appeal to raise funds to help reverse the impacts of storms is still open for any kind donations you may be able to spare. Any continued donations will still be spent on storm-proofing the islands and developing protocols to deal with seabirds and seals effected by storms.

Although these storms aren’t as bad as last year’s, we’re still battling with a flooded toilet, leaking windows in the library at North Haven, broken garage doors, guttering that’s come off and our boat almost flying down the cliff! But apart from those and a few other small damages, everything is good.

 

Seal pups on Skomer

We have been worrying about the seals and are hoping that they have been OK! We cannot tell how the storm has affected them just yet but we will let you know as soon as we do.

However, seal pupping on Skomer is drawing to a close for 2018. It has been a good season for the seals with no disastrous storm events like last October, and well over 200 pups have been born! At least one of the storms this year corresponded with neap tides which meant the pups had somewhere to retreat to away from the crashing waves. So it seems that survival to weaning (around 3 weeks of age) will be good this year. Of course, knowing this is only possible due to the long-term monitoring that we do on Skomer. This monitoring is of vital importance if we are to understand the population dynamics of the seals and safeguard them for future generations to coexist with and enjoy.
