Wilding is the story of the how the Burrell family ditched intensive farming of their estate at Knepp and returned the land to the wild. 
Isabella Tree takes you through the decision making and reasoning behind all their choices, such as why they introduced certain animals, as well as describing the effects they had on the land. Hearing about all the incredible animals and critters that returned to the area when the land was left to (mostly) manage itself is inspiring. I immediately started telling my parents off for mowing the lawn! 
Tree also explains how a lot of what they have done on the land could be done on smaller scales around the country to help with flood plain management, bring back species that are struggling in the country, as well as managing farms with climate change in mind. 
My only gripe with this book is the slightly preachy tone Tree sometimes has when she talks about some of the topics she touches on. She and her husband are privileged to have such a large piece of land to return to the wild. They also seemed to find it easy to make the right contacts in the conservation world to get the right advice on what to do with the land. 
Still, the work they have done and carry on doing at Knepp is incredible, and my only hope is that people who read this are inspired to allow the wild to be. Stop cutting grass verges so much, allow hedges to get a bit wild (unless it blocks the view when driving of course, safety first), and for gods sake stop hard landscaping everything.
