The 3-30-300 test

Yes, yes, and yes would be my answers to the 3-30-300 test. (I can't actually count the number of trees that I can see out of the windows of our house.) But then, we don't live in a city and my home county of Northumberland is blessed with trees and open spaces.

The 3-30-300 test is simple. Every home, school and office should have a view of at least three trees, be in a neighbourhood with 30% tree cover, and be within 300 metres of a park.

Proposed just a few years ago by Cecil Konijnendijk, the rule has spread quickly. The Italian city of Florence committed to planting 50,000 trees by 2030 under the framework. Fort Collins, Colorado made it a formal planning target. Cities from Haarlem, Netherlands to Saanich, British Columbia have followed suit.

Its popularity makes sense: 3-30-300 is a catchy, straightforward test that sets a clear benchmark for measuring equal access to nature.
