This book was such an eye-opener to write. Interviewing the 24 image-makers whose work is featured here, I learned so much more about the beauty, resilience and diversity of trees in different parts of the world, as well as their extraordinary capacities to sink carbon, purify air, support biodiversity and stabilise the climate.

To write about trees in a time of climate and ecological emergency is to write about love and loss, beauty and greed, destruction and redemption... so the journey of making this book was quite a wild one. My intention was to make a book that was first and foremost about wonder, because as the pioneering eco-activist Rachel Carson said in 1954, "the more clearly we can focus our attention on the wonders and realities of the universe about us, the less taste we shall have for destruction." But I could not turn away from the destruction, and there are several very powerful bodies of work in the book that show the devastation being wrought on trees as a result of development, disease, drought and disregard. But yellow is the colour of hope, and that’s the overriding emotion I felt after collaborating with such incredible photographers, activists and storytellers. 

This is a big and gorgeously produced book, one I think every tree-lover will treasure. In the interests of protecting the Amazon rainforest rather than the Amazon conglomerate, please buy it from your local bookseller or direct from the wonderful indie publisher Hoxton Mini Press, who have ensured it's a totally carbon-neutral publication and are even planting a tree for order.
