The author’s credit reads ‘Henrik G. Dahle and Co’. The following are the Co’s I can remember. As a tree claps its leaves, I give my grateful applause to: 

All my teachers, supporters and muses: The many authors, journalists, Wikipedians, bloggers, vloggers, filmmakers, and artists whose research I’ve plundered and been inspired by. Along with the academics, I want to acknowledge the co-authors and researchers who often namelessly bring illumination. 

Charlotte Du Cann, Cate Chapman and Nick Hunt: The editors who I worked with on various drafts of the book over several years approached my work with a light touch while provoking enormous improvements to content and clarity – asking great questions, offering their broad knowledge and detecting bullshit. Of course, I take full responsibility for any remaining bullshit or lack of clarity. (I’ve made many changes since anyone had a look). I’ve been deeply privileged to work with these exceptionally talented and generous people. Shaun Chamberlin gave valuable encouragement as the first reader of a very early (rubbish) draft, and Prof. Gauntlett, who was with me all the way…

I thank Ruth Reddecliff for inviting me to her Pirate Party, and for her and Mike Reddecliff’s playfulness, which started it all. To my brothers Peter Gauntlett, who pushed me up a tree all those years ago, and Magnus Grundtvig, whose head I stood on to get into one.

Thanks to Equator Goldstein who, when I was 13, suggested I carry a notebook.

Tree tattoos (canvas, not artist credited. Collected from people I met along the way: Gustav Ahlcrona p.404, Lizzy Carey (bottom)p.411, Yvette p.409, Natacha Higo p.413, Ida S Dahle p.417, Ana Gabriel Mendes p.420, Amalie Basse p.422, Nathan Goodwin p.424, Nils Symanczyk p.427, Flaminia de Martino p.429, Anonymous p.406, 408, 411(top), 418, 430. (For subsequent versions of the book I’d like tattoos on more than one black/brown skinned person, to reflect the Greenprint’s intent).

And, if you’re thinking, ‘Where’s my name?’ then it probably ought to be here. Please close your eyes, imagine my apology, and write it in… Then, let me know, and you’ll be included in Version 02.

And last, but perhaps, in fact, first, I thank all the trees, and their inhabitants, who I met along the way.
