The tree will be planted at the charity’s Dundreggan estate by Scottish wildlife filmmaker, Gordon Buchanan from the BBC’s Big Cat Diary, Springwatch and Natural World. The estate is home to over 60 species that are priorities for conservation in the UK.

Trees for Life founder and executive director, Alan Watson Featherstone, said: “With the critical global issues of climate change, deforestation and loss of biodiversity, helping to restore the Caledonian Forest is a positive and practical local solution that anyone can support and take part in.”

To celebrate planting the millionth tree, the charity is running a lecture tour throughout Scotland and England in April, led by Featherstone and featuring ‘before and after’ photographs of the Caledonian Forest.

Trees for Life is also running a sponsored walking and cycling relay across the highlands on 5–19 May. The ‘treelay’ will link all the sites that the charity has worked on since its establishment 23 years ago, in 1989.
