Trees & reforestation

Forests absorb carbon, shelter wildlife, and anchor watersheds — yet billions of trees have been lost to logging and land conversion. This archive tracks the science, policy, and community efforts driving reforestation forward, from Indigenous-led land restoration to large-scale planting programs showing measurable results.

Scottish forest, for article on Scotland reforestation

Scotland’s forests are the largest they have been for 900 years

Scotland’s reforestation story just keeps growing: tree cover has tripled over the past century, climbing from under 6 percent of the country’s land to roughly 18 percent today. That’s close to forest levels not seen since medieval times. Behind the numbers are decades of work by government agencies, private landowners, and rewilding groups like Trees for Life, who’ve been steadily replacing fast-growing conifer plantations with native species like Scots pine, birch, and oak. Public enthusiasm is striking too — around 80 percent of Scots backed Highland reforestation in a 2021 survey. Scotland’s recovery is a hopeful reminder that landscapes stripped bare over centuries can begin healing within a single lifetime, when communities decide they want them back.
