‘Heartwood’, a poem by Robert Macfarlane written for the people of Sheffield during their battle to save more than 17,000 trees from felling, has been turned into a linocut poster by Nick Hayes, and made available for free hi-resolution .jpeg and PDF download.

‘Heartwood’ is, writes Robert on thelostwords.org, ‘free to use, anywhere in the world, without any need to seek permission or give credit, for anyone defending trees, woods or forests from unjust felling. Feel free to post it, set it to music, sing it, share it, read it aloud, turn it into charms against harm…’
