Prince William has been given some exciting new patronages by none other than Queen Elizabeth II and Prince Philip! As Hello! shares, it was revealed on Monday that William is now patron of two environmental organizations after his grandparents passed on their titles to him.

Prince William's new causes focus on biodiversity and birds

Prince William takes over from Queen Elizabeth II as patron of Fauna and Flora International— a position the queen had maintained for nearly 70 years! As Hello! mentions, the organization is devoted to environmental biodiversity, protecting ecosystems and species that are at risk as well. They are also determined to provide scientifically-backed, sustainable solutions for the planet.

FFI helped found the Duke of Cambridge's anti-wildlife trade organization United For Wildlife, and were also recently named Global Alliance Partner of his new initiative, the Earthshot Prize! As well, William has succeeded Prince Philip as patron of The British Trust for Ornithology, which is an organization focused on the protection and preservation of birds. The Duke of Edinburgh held the role for nearly 30 years before passing the title down to his grandson!

Prince William is known for his environmental activism

Prince William has been known to be a strong advocate for the environment, so his being given these specific patronages comes as no surprise! The royal recently opened up about fatherhood and conservation in a brand-new documentary for ITV revealing how his children— Prince George, Princess Charlotte, and Prince Louis— have helped to inspire his environmental mission.

Along with Duchess Kate, William and his children also got to have a chat with Planet Earth's David Attenborough in September. And while it had been some time since the Duke of Cambridge and Queen Elizabeth II stepped out on official business together, last week the duo was seen visiting the Defence Science and Technology Laboratory, marking their first joint royal engagement in 3 years!

Prince William gave the keynote speech in Dublin on Wednesday.
