Join Isabella Tree and butterfly man Neil Hulme as they anticipate the exciting reintroduction of the black-veined white – a butterfly that went extinct in Britain a hundred years ago. Standing in front of the cages at Knepp where butterflies recently imported from Spain have laid their eggs, Neil is like an anxious midwife. Will the caterpillars survive the winter and the various predators insinuating themselves through the netting? How many butterflies will emerge in spring for their releas...

Isabella Tree catches up with Carl Sayer, Professor of Limnology & Freshwater Ecology at University College London - aka the Eel Man - as he prepares for this year’s survey of Knepp’s eels. Once bountiful in the UK, eels have all but disappeared from most water systems, impacted by overfishing and obstructive dams and weirs that prevent their migration. Carl has loved eels since he discovered them as a boy and relishes the mystery that still surrounds their adventurous lifecycle. Happily,...

And pick up some simple tips to encourage the best pollinators, predators, soil fertilisers and decomposers in your garden. Isabella Tree co-founded the Knepp ...

For many people, rewilding is a one-trick pony – it’s great for restoring nature and wildlife, but does it do anything for climate change? In this episode, Isabella asks her daughter Nancy Burrell about her doctorate research at Knepp and the astonishing findings that are changing how rewilding is valued as a mechanism for storing carbon. Join them as they wander through the scrubland at Knepp, visiting the sites where Nancy and her team excavated 270 trees, roots and all, to measure how much...

Isabella Tree catches up with two of the White Stork Project volunteers, Tim Morgan and Rosemary Dewan, as they prepare food for the non-flying storks in the pen at Knepp. It’s a freezing day with slashing rain, typical of the weather the unflinching volunteers have had to face almost every day this winter. The project relies on around 25 stork-feeding and 30 stork-monitoring volunteers – out in the wildlands of Knepp come rain or shine. Their purpose – to help establish and observe the first...

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 e...

Not according to Mark Elliot, beaver expert and Isabella Tree’s latest podcast guest. Licensed beaver pens – designed by Government as the first stage to wider release over three years ago – are beginning to fail. Beavers, including those installed in a six-acre pen at Knepp, have begun burrowing out of their watery prisons. As Isabella leads Mark through the incredible new wetlands created by Knepp’s AWOL beavers, he describes the importance of beavers in flood defence, neutralising water po...
