Species are located on the isle of Arran

The public is being urged to help save endangered tree species in Scots woodlands.

The National Trust for Scotland made the call as part of a wider campaign to support the regeneration of native woodland.

It is wanting to replant trees in woodlands that have faced been decimated because of climate change.

The charity has launched a ‘Dedicate a Tree’ appeal where supporters can help protect the woodlands for “generations to come”.

Catacol whitebeam is one rarest species in the world and grows in Glen Catacol on the Isle of Arran. The public is being asked to help to save this as well as the the cut-leaved whitebeam trees.

Kate Sampson, the NTS’s senior ranger at Brodick Castle, Garden & Country Park and Goatfell, said: “Glen Rosa is a fabulous iconic Highland landscape in the heart of Arran, which has been depleted of trees since humans came here around 4,000 years ago – by people building roundhouses and shielings, then by sheep, and now by deer.

“People have had huge impacts on this amazing landscape – and of course on other landscapes around Scotland – and now our supporters at the National Trust for Scotland have been working to put back these trees.

“To date, we’ve planted around 39,000 native trees in Glen Rosa, thanks to generous support from donors and players of the People’s Postcode Lottery, which allowed us to fence off a large area from deer.”

“We hope that our members and supporters will continue to back our wonderful woodland regeneration projects and progress – on Arran and the other wonderful and important landscapes supported by our charity’s Dedicate a Tree appeal."
