More than 200 trees have been planted at Threave Estate.
Around 10 volunteers from the National Trust for Scotland, HSBC UK and the Galloway Glens Landscape Partnership planted the native aspen trees at Kelton Mains.
The work was part of the Threave Landscape Restoration project.
The trees were planted at Millburn to improve the banks as a wildlife habitat.
Estate manager David Thompson said: “These new trees are the next step in our plan to restore the natural features that are so unique to this part of the Threave Estate.
“The benefits of these trees will be immediate – from the moment they go in the ground, they improve the biodiversity of this site and they’ll keep doing that for centuries to come. This is a really exciting step for our project to protect and restore Threave’s landscape now and for years to come.”
The project, which aims to transform 91 hectares of land, is being supported by HSBC UK, the Galloway Glens and the Heritage Lottery Fund.
Chief executive of HSBC UK Ian Stuart said: “A challenge as significant as climate change can only be tackled in collaboration. Our ambition is to help open the door for National Trust for Scotland to explore new areas of agroforestry management and how nature-based solutions are being scaled and delivered to tackle climate change internationally.”
Galloway Glens project officer Nick Chisholm added: “This is a super ambitious project that demonstrates a new way of managing and interpreting our landscape. Humans will be the spectators and biodiversity will be the winner.”
It is hoped the new system will be up and running this month.
