The 3-30-300 Rule

Straight from the source: Maria Burnett sits down with Cecil Konijnendijk, the urban forester behind the world-famous 3-30-300 rule.

Together, they unpack how this deceptively simple guideline — 3 trees in view, 30 percent canopy cover, and 300 meters to green space — can reshape urban planning, public health, and social equity.

From city streets to forest roots, this is a global idea with deeply personal beginnings and a conversation that might just change how you see the world outside your window.
