'Be vigilant' warning as weasel spotted on island

The Isles of Scilly Wildlife Trust said the weasel had been seen at the Garrison

Wildlife experts have asked residents of the Isles of Scilly to look for signs of a weasel after one was reportedly seen on St Mary's.

The Isles of Scilly Wildlife Trust (IOSWT) said it was "taking this report seriously" because of "the delicate balance of nature on Scilly".

A detection dog was deployed to some of the islands in February to check for signs of rats and mice as they can pose a threat to the populations of storm petrels.

The IOSWT said the weasel had reportedly been seen at the Garrison on Friday and they asked islanders to "keep a close look out" and share any sightings with the team.

'Need to be vigilant'

The charity said: "Many species such as our breeding seabirds can only thrive in the absence of mammalian predators.

"Biosecurity is a high priority for the Isles of Scilly.

"This report is a sharp reminder that we need to be vigilant that we don't bring non-native species or plant or animal diseases to Scilly."

The charity said it would set trail cameras in the area in an attempt to get photographic confirmation of the mammal.

It advised islanders: "If you do spot what you think could be a weasel, see if you can see its relatively short and very furry tail. If at all possible, please get a photo."
