Million Tree Challenge

The Million Tree Challenge seeks to inspire Londoners to plant one million trees to enhance environmental and human health in our Forest City.

Now that we have reached a quarter of a million trees registered, 2016 is set to be a great year to really push the total up. We need everyone in London to be part of this. Why not make plans now how you can plant a tree on your property this year - or donate to have trees planted. If you have planted any trees since 2011, please take the time to register them at and be counted!

Watch our 1 minute animation that describes what London's Million Tree Challenge is.
