ANOTHER Scots island has been added to a rising listing of these the place public landings are being suggested to cease, as a result of ongoing avian flu disaster.
NatureScot is advising public landings cease on the island of Mousa in Shetland, to restrict the unfold of avian flu and provides seabirds the very best likelihood to outlive and recuperate from the present extreme outbreak.
The island joins the listing of 23 different Scottish islands the place public landings have been suggested to cease till chicks have fledged.
The Mousa Boat will cease operating journeys to the island from thirtieth July for the rest of the 2022 season.
Historic Surroundings Scotland can also be closing Mousa’s well-known Iron Age broch till mid-October.
Mousa is residence to round 11,000 breeding pairs of European storm petrels, referred to as alamooties in Shetland, representing 2% of your complete world inhabitants of the birds.
A number of hundred breeding pairs make their residence inside the partitions of Mousa Broch.
NatureScot has assessed that the chance of tourists transferring the avian flu virus across the island on their footwear and contained in the broch is just too nice.
NatureScot says it has thought-about “all doable routes of an infection” for the small and elusive seabirds.
Storm petrels seldom combine with different seabirds, as they feed far out to sea throughout the day and solely come ashore beneath the duvet of darkness.
The virus that causes avian flu can survive for a lot of days on fowl faeces and soil.
There’s a excessive danger of petrels touchdown and choosing up the virus the place guests have walked each contained in the broch and at different locations the place they nest on the island.
Eileen Stuart, NatureScot’s Deputy Director of Nature and Local weather Change, mentioned: “Limiting visits to Mousa was not a straightforward choice, however we’re more and more involved concerning the horrible impact avian flu is having in Shetland’s seabird colonies.
“Along with the Scottish Authorities and the Animal and Plant Well being Company, we now have checked out biosecurity measures to permit the broch to stay open to the general public whereas the storm petrels are nesting.
“Nonetheless, the logistics of getting sufficient clear water out to the broch and guaranteeing that guests can clear and disinfect their footwear adequately has proved too difficult for this season.”
Helen Moncrieff, RSPB Scotland’s Shetland Supervisor, mentioned: “We vastly recognize the choice to cease operating the boat service to Mousa to present the dear seabirds on the island the very best likelihood of survival throughout this devastating outbreak of avian flu.
“Storm petrels breed throughout the island, together with the Broch, and draw 1000’s of tourists to the reserve.
“The affect avian influenza is having on tour operators is extremely robust, notably after the previous couple of years.
“We’re grateful for the sacrifices that The Mousa Boat firm, and different tour operators elsewhere in Scotland, are making to assist restrict the unfold.”
NatureScot thought-about the prevailing biosecurity measures have been ample for guests strolling around the island on the footpaths however not for coming into the broch.
Mousa Boat took the troublesome choice to cease operating as a result of there are usually not sufficient passengers to make operating the service viable if the broch is closed.
Visiting cruises, leisure boats and sea kayakers are requested to not land on Mousa till mid-October as there are at present no biosecurity preparations in place on the seashore by the jetty and there are storm petrels and Arctic terns nesting on the different potential touchdown websites.
NatureScot has mentioned it’ll assessment this danger evaluation in March 2023 within the mild of analysis into how avian influenza virus spreads on completely different surfaces and details about the predominant pressure of the virus circulating in wild fowl populations.
This info might be used with the intention of devising efficient biosecurity measures to maintain Mousa Broch open to guests whereas defending the storm petrels from avian flu.
