Peter Williams is a local musician and music teacher, who founded the Chippenham based charity fundraising band ‘Shake the Bucket’. Since 2005 the band have raised over £75,000 for local and national causes.

Peter is also passionate about trees, and as Coordinator for North Wilts Friends of the Earth helped create a new woodland near Castle Combe. He also started the Chippenham Tree Mapping Project, that will be used as part of the Forest Schools initiative.

“Avon Needs Trees is a positive, productive, hands-on project that has the potential to make a big difference. Not only for carbon sequestration but for flood management, biodiversity and landscape protection. Doing nothing is not an option”.

Gavin took some time out from his IT career in 2015 and planted 15 acres of native woodland a few miles from his home in central Bristol. Along with a wealth of practical woodland skills Gavin has professional experience of managing teams of volunteers. Gavin keeps bees and is interested in agroforestry.

John Chew

John has been a primary school teacher for over twenty years. His favourite subjects have always been science and geography, seizing every opportunity he can to introduce children to the wonders of the natural world. More recently, he has become passionate about sharing knowledge and understanding of climate change with children of all ages. He is currently studying for accreditation in the UN Climate Change Learn programme and is aiming to become an accredited Forestry School Educator later this year.

“I have found children to be very concerned about the state of the planet; the animals, forests and ecosystems that are being destroyed and sometimes lost for ever. Let’s get them re-engaged with wilderness and encourage them to learn about our precious natural world. They are our future and perhaps our greatest hope in sorting out the mess we’ve created.”

Andy chester

Andy has a lifelong love of wild life and wild places which began on the heaths  and woods of Dorset and the New Forest. He has spent the last twenty years working at Natural England, creating opportunities for people to be in the English countryside. He cut his teeth on the roll out of open access rights – the so called ‘right to roam’ – and was a founding member of the team that is creating the England Coast Path. He brings experience of balancing and reconciling outdoor recreation with safety, nature conservation, farming and other land uses.
