Nikki Jones MSc is a writer, speaker and campaigner on UK and global energy trends. For several years she wrote for an industry magazine on the political economy of oil and gas but in recent years has devoted her time to public talks and blogs to help individuals understand their energy consumption and why it matters.

She has wide experience in the charitable sector, having worked for Age Concern England, the National Council for One Parent Families, the Alzheimer’s Society and Carers’ Centre. Her roles have spanned service development, press and publicity and fundraising. She worked as a press officer for the BBC for six years. 

Cathy Bedford

Cathy Bedford is a freelance researcher, writer and trusts and foundations fundraiser, with ten years’ experience of working in the charity sector and a past career in documentary film-making at the BBC. Cathy grew up on a farm in Devon where she developed a deep love for the countryside and an interest in trees, rivers, natural history and rewilding. Now based in Bristol, when not working she spends her time playing the piano and cello, walking, swimming and wild gardening. 

“For me Avon Needs Trees offers a fantastic focus for my interest in and concern about the natural world – a chance to impact positively, in practical ways, on a local scale, on our threatened environment”

Gavin Spittlehouse

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.”

Harriet Alvis

Harriet Alvis is an aquatic ecologist working in river restoration in the charitable sector for the West Wales River Trust. She has a passion for re-wilding and reducing our impact on the natural environment, as well as re-engaging people with it. In her free time, she enjoys horse riding, kayaking and surfing.

Chris Horwood has had a career in international development and aid mainly in Africa and Asia, but is currently studying a Masters in Forestry at Bangor University as he navigates a switch into the woodland and forestry sector. “Given the current environmental emergency I want to spend the rest of my working life involved in planting trees and improving our collective stewardship of trees.”

Alister Wynn

He is now studying for an MSc in Forestry at Bangor University and is enjoying spending less time in front of a computer and more time with his hands dirty. “I got involved with ANT as they are an inspiring organisation with a great mission. We need more trees, a lot more, which is why I think the work of ANT and others like them is vital for our collective happiness and future”.
