70 years ago, the Thames was “biologically dead”. Now it’s thriving.

400 years ago, beavers were hunted to extinction. Now their numbers are increasing.

The actions we take now to restore nature in London will be felt for generations to come.

This is what rewilding looks like.

Through my Green Roots Fund, we’re working with Londoners to restore nature, boost biodiversity and help protect neighbourhoods from the climate crisis.

It’s about healthier rivers, thriving wildlife and a greener London for everyone 🌱

We started small and built from there.

In 2023, a family of five beavers arrived in Ealing.

In 2024, with Enfield Council, we expanded their beaver enclosure.

And they’ve settled in fast: baby beavers have been born in Ealing and Enfield 🦫✨

As you might have seen on David Attenborough’s Wild London programme, beavers are thriving in Ealing and Enfield - the first in London for almost 400 years.

Beavers help clean our waterways and protect against flooding by building dams 🌊
