Merlin Hanbury-Tenison has the image of his favourite oak tree tattooed across his back. Wherever I go, I feel like I am carrying the forest and its story with me, he says. This story begins in 2020 when he returned to Cabilla, his familys 250-acre farm on Bodmin Moor. He was suffering from PTSD after three military tours in Afghanistan, his wife Lizzie was floored by repeated miscarriages, and his father Robin was stricken with Covid. In the woods where he had played as a boy, Hanbury-Tenison found solace in one of the last fragments of Britains temperate rainforest, a rare habitat dating back 5000 years. Here, beneath the Mother Tree oak was the best place possible to heal, restore and recover. Now Hanbury-Tenison is on a mission to give others the chance to have access to this healing power and to heal the rainforest in return. In four years, he has hosted 3000 people at Cabillas wellness retreat, planted 100,000 trees and is using the farm as an AgroRainForestry blueprint for his Thousand Year Trust, which aims to triple Britians rainforest cover to one million acres within 30 years. We need to listen, says Isabella Tree, author of Wilding. What Merlin has learnt from the healing power of nature will help us all.
