"Researchers from WRI’s Global Restoration Initiative, Land & Carbon Lab and Meta have developed a groundbreaking AI foundation model that we’ve used to produce the world’s first global map of tree canopy height at a 1-meter resolution, allowing the detection of single trees at a global scale."

A great resource as long as it is not used to map global forests, or decide where to plant billions of trees in the name of forest restoration. Tree canopy height does not define forests.

Good point about the savannas!
Tree density obviously matters too.

More importantly, functional traits of plant species matter, such as traits that make them adapted to fire, herbivores, sunlight, warmth and seasonal rainfall, which remote sensing cannot yet capture.
