O TYM ODCINKU
Isabella’s guest is Harriet Rix, the Indiana Jones of tree science. She’s chased down rare trees in some of the remotest, wildest places in the world, and in the UK she’s worked for DEFRA, researching tree diseases and strategies for trees in cities. Her latest book The Genius of Trees explains how trees have influenced, even controlled, life on our planet.
Wandering through the ancient oaks and young saplings of Knepp’s scrubland, Harriet opens up a perspective of millions of years of tree evolution. Far from being static and vulnerable, as we tend to think of them, trees are resilient survivors, agents of their own destiny – and quite possibly ours. Harriet explains the secrets of genetic diversity and how, by encouraging natural regeneration as we do at Knepp, we can help trees adapt to climate change and resist disease. She shares extraordinary insights, including that the English oak, our country’s pride and joy, is originally American.
Isabella Tree co-founded the Knepp rewilding project with her husband, Charlie Burrell. She is an award-winning author, including of the best-selling book, Wilding: the return of nature to a British farm, which was made into a major motion picture in 2024.
