Beyond tree cover: mapping the world’s forest types

October 22, 2026 ResearchMaxim Neumann and Charlotte StantonA new 10-meter resolution map shows which of the world's forests are natural, planted, or farmed, and how they are changing over timeProtecting the planet's forests starts with a simple question: what type of forest are we looking at? From space, an old-growth rainforest, a eucalyptus plantation, and an oil palm estate can look like the same patch of green. But they hold very different amounts of carbon and biodiversity. Telling them apart, and knowing how each patch has changed over time, shows us where conservation is working and where natural forests are being converted into plantations and farms.Today, Google DeepMind and Google Research, together with the World Resources Institute (WRI) and the International Institute for Applied Systems Analysis (IIASA), are releasing Forest Typology (ForTy) 2020, a global map that categorizes every 10-by-10-meter patch of land on Earth into six distinct forest and land-use types, a key baseline for the EU's deforestation regulation. Alongside it, we're sharing an early time series that tracks how these forests changed each year from 2017 to 2025, including where natural forests were replaced by plantations or farms. For the first time, users can see at 10-meter detail worldwide, year by year, not just where forest was lost, but what replaced it: a timber plantation, a tree-crop farm or other land.Why "tree cover" isn't enoughAll forests store carbon and, together, forests are home to most of the world's land-based plant and animal species. But a forest’s ecological value also depends on its history: a primary forest that has never been cleared holds far more carbon and biodiversity than a single-species timber plantation that is harvested every decade or two.Most global maps only indicate whether trees are present. That's a challenge for those trying to protect natural forests. The European Union's regulation on deforestation-free products (EUDR), for example, requires that products like coffee, cocoa or palm oil do not originate from land that was forest in 2020 and has since been converted to agriculture. Similarly, wood products, such as furniture, must also be free of forest degradation: they can't come from primary forests that have since been converted into plantation or planted forests, or from naturally regenerating forests that have since been converted into plantation forests. As a result, companies and regulators need to know not just where …
