David Lindo, naturalist, writer and broadcaster, joined London Wildlife Trust in June 2016 as the Trust’s first ambassador. David helps to promote the Trust’s work across London, sharing the Trust’s vision of a London that is alive with nature, where everyone can experience and enjoy wildlife.

David has been fascinated by wildlife and nature since childhood and is seldom seen without his trademark binoculars, one eye to the sky as he scans for wild birds. Known as the Urban Birder, David was brought up around Wembley and is now a regular television presenter, always happy to share his knowledge and enthusiasm with a wider audience. He is a familiar figure on Wormwood Scrubs, his favourite ‘patch’ for spotting the capital’s birdlife. Visit David's website:

Alison Steadman

London Wildlife Trust ambassador Alison Steadman

Olivier Award winner Alison Steadman joined the Trust as an ambassador in November 2016. Well known as an actress, Alison is also a wildlife enthusiast and nature documentary TV presenter, with a passion for the wild.

Alison’s love of nature started as a child in a small Liverpool back garden, and she fully supports the work of the Trust in engaging urban children with nature and wildlife. She is keen to ensure as much of London remains natural as possible, as she says: “It’s really important we keep our garden species. These big housing developments can be really unfriendly to nature and we need to do more to keep our green spaces."

Tom Holland

Award-winning author Tom Holland joined the Trust as an ambassador in March 2017 and is proof that an interest in nature and wildlife can be sparked at any age, at any time. The historian moved to London in his early 20s, and it was this change that brought about his interest in the natural world: “Being in the city and seeing foxes and suddenly becoming intensely aware of the wildlife around me made me realise what I had missed in the countryside. You think of all the obstacles to wildlife there are in London, and yet it is all around us.”

Tom is the author of acclaimed works of history such as Persian Fire and Rubicon, and has written for the Evening Standard on the need to protect London’s dwindling hedgehog population. His favourite London species are the hedgehog and the sparrow: “I find it upsetting their numbers have declined so much. Sparrows are the spirit of London’s wildlife.”
