An initiative to save one of Scotland’s most endangered species of tree has been launched in the Cairngorms National Park.

Aspen provides a vital habitat for rare wildlife, plants and fungi and is one of Scotland’s most important native trees.

The tree was once common but deforestation and overgrazing has caused it to largely disappear from the Scottish landscape.

A new partnership between the rewilding charity, Trees for Life, and the Cairngorms National Park Authority will map the location and health of the existing aspen population and use the information to guide the planting of new trees.
