When she isn't enjoying an afternoon tea or strolling the grounds of her palace with her corgis, Her Majesty Queen Elizabeth II likes to nurture her side hobby of conserving forests around the globe. The Queen discusses her love of trees with Sir David Attenborough in a new nature documentary called The Queen's Green Planet, airing on ITV in the UK on April 16, the Independent reports.

While walking through the gardens at Buckingham Palace, Sir David and the Queen chat about the royal family's history with trees as well as the legacy she hopes to leave to future generations. With the new initiative, The Queen's Commonwealth Canopy (QCC), she aims to create a global network of forest conservation projects connecting all 53 Commonwealth nations. When we don't see the Queen at her home with Sir David, we follow Prince Harry planting trees in the Caribbean and Prince William visiting Canada's Great Bear Rainforest with his family.

The Queen's insights on big topics like climate change come with amusing tidbits about her personal life. In the documentary, she reveals that her love of trees has had some unexpected consequences: "I’ve been quite difficult to give presents to so … they’ve said, ‘Oh, let’s give her a plant.’”

Leading up to the documentary's premiere later this month, viewers will have a chance to take part in the Queen's initiative. The ITV programs Good Morning Britain and This Morning are inviting people to sign up to receive their own saplings, which will be shipped out for planting in August of this year.
