Seabirds and sewage among UNESCO status challenges

The Isle of Man became the first entire country, including its surrounding seas, to be given the status, which is reviewed every 10 years.Image source, BBC NatureImage caption, The Manx shearwaters population has succesfully recovered following a rat cull Success storiesAmong the successes of the Biosphere's first decade was the return of juniper, a native shrub that had been lost from the island.The last native plant on the island was dug up from Glen Auldyn in 1947 in an attempt to save it, but died soon afterwards.Since 2016, it has been replanted in the uplands, with surveys showing "encouraging survival and growth".Meanwhile on the Calf of Man, controlling rats - referred to locally as "longtails" to avoid bad luck - has helped the Manx shearwater recover to about 1,500 breeding pairs.Nine new Marine Nature Reserves have been created since 2016, and together they now cover more than half the sea within three nautical miles of the coast.By the end of last year, 420 hectares of damaged peatland had also been restored.Image source, Manx ScenesImage caption, The Calf of Man, off the southern tip of the island, is an important breeding ground for seabirdsStill work to doA 2024 assessment found 48 of the 166 bird species regularly seen on the island were on the red list of greatest conservation concern. Another cause for concern was that monitoring has found declines in young salmon.The report also acknowledges sewage is still being discharged into the sea at Peel and in Garff, though work on a new treatment works for Peel began last year.It says Biosphere status is "not a claim that everything is working as it should", and that its credibility depends partly on being prepared to admit where it is not.Biosphere Isle of Man chairman Jason Bissell said there was "much to celebrate from our first decade, and much still to do".The report has been published alongside an exhibition at the Manx Museum entitled Jeihosphere, which tells the Biosphere's story through 10 objects, running until 28 February.Get in touchTell us which stories we should cover on the Isle of ManMore on this story
