North America has lost a third of its bird population in the last half century, we learned in a recent news report.
So it is with other parts of the world, too. Isabella Tree has written a fascinating and beautifully written book about her corner of the world, a 3,500 acre estate in Sussex, England, a place which had been farmed for centuries until costs outran income and Isabella and her husband Charlie Burrell could no long afford that way of life. All the equipment, pesticides, and herbicides they needed to farm the difficult clay soil had them deeply in debt.
In a radical move, they let the place run wild.
And the birds came back. And the butterflies, the worms, numerous insects, and a riotous resurgence of plants, trees, and scrub.
It all began in 1999 when a tree expert diagnosed the reason their ancient oaks were dying. The soil had been compacted when underground earthworms and mychorrhizae were destroyed by the action of tractors and the elimination of wildlife. Twenty years later, their estate is teeming with life, visible and invisible, and the Burrells have reintroduced to the land red, roe and fallow deer, Old English Longhorn cattle, Exmoor ponies, and Tamworth pigs. The couple now run safari tours of their land, and sell the organically raised meat of their cattle, making more money than they ever did as farmers.
Making money is not entirely the point, Tree emphasizes. But the need to survive financially drove the decision to rewild their estate. The miraculous regeneration of the land through letting nature take its course has astonished them as it has others. While some of their neighbors complain about the untidiness of their once neatly hedged farm, the Burrells revel in its rampant sexuality. That’s a big theme when animals and insects are closely observed. Who knew a purple emperor mating display could be so riveting? Tree’s gorgeous writing keeps the reader glued to the page.
This is an important book, and a hopeful one. The degradation of the planet through monoculture, through the use of artificial fertilizers and heavy equipment has taken place over the last hundred years. But in only twenty years, Isabella Tree and Charlie Burrell have reversed the course in the land they own. It’s a lesson for everyone.
