Having helmed over 40 primetime programmes, her work is wide ranging, from animal behaviour and wildlife series such as Super Smart Animals and Nature's Epic Journeys, to hard hitting environmental documentaries such as Meat: A Threat to our Planet? and Drowning in Plastic, which investigated the ocean plastic crisis and successfully raised the level of public debate on the important topic. Liz also presented the award-winning Galapagos - a three-part series which saw her join a team of scientists to carry out ground-breaking research and undertake her first submersible dive to 1km beneath the waves, the deepest anyone had gone on the Archipelago

Her most recent projects include, four-part series Liz Bonnin's Wild Caribbean which aired last Autumn on BBC Two and saw Liz return to her Caribbean roots, to discover the region's lesser-known, remarkable wildlife and meet the extraordinary people who are fighting to save it. Our Changing Planet which began airing on BBC One during spring 2022 and is a definitive seven-year diary, documenting the fight to save our planet's most threatened ecosystems - Liz's latest episode for the series is a coral reefs special airing in spring 2024 . In 2023, on Sky Nature with Arctic from Above, Liz joined scientists in one of the planet's last great wildernesses to reveal fresh insights about how Arctic wildlife is faring in the face of climate change. And in Secrets of the Jurassic Dinosaurs for BBC Two, Liz travelled to Wyoming to investigate a dinosaur graveyard that is transforming the way we think about the Jurassic. 

In addition to her television work, Liz presented What Planet Are We On? for BBC Sounds and Radio 5 Live. The podcast series looked at the impact we are having on our planet and the practical solutions we can adopt to create a more sustainable future. Guests included Sir David Attenborough, Idris Elba and Christiana Figueres. Liz most recently hosted Dead River,  a compelling podcast series telling the story of the worst environmental disaster in Brazil’s history and the law firm who took on over 700,000 plaintiffs to bring the largest case of its kind to the UK courts.

Liz has a Masters degree in wild animal biology from the Royal Veterinary College and Zoological Society of London. Bonnin regularly speaks at and hosts science, natural history, and environmental events, including The National Science and Engineering Competition, the Natural History Museum's Wildlife Photographer of the Year Awards, and New Scientist Live. She was elected the first female president of The Wildlife Trusts in the UK, and was recently awarded an Honorary Fellowship of the British Science Association. She is also frequently invited to speak to the business sector about the systemic transformation needed to create a healthy planet and sustainable future.
