Key Takeaways
- Rewilding can be applied to spaces of all sizes, from large landscapes to home gardens.
- Isabella Tree and her husband transformed 3,500 acres of failing farmland into a thriving nature reserve.
- A three-step method can guide individuals in rewilding their own small green spaces effectively.
- Rewilding involves embracing a natural aesthetic and relinquishing absolute control over nature.
Deep Dive
- Isabella Tree inherited 3,500 acres of struggling farmland in southeast England.
- After 17 years, conventional farming methods resulted in significant debt.
- The decision was made to pursue a radically different approach by working with nature rather than against it.
- Initial rewilding steps included removing fences, restoring natural water flow, and reintroducing free-roaming animals like cattle, ponies, pigs, deer, and beavers.
- This led to rapid ecological recovery, attracting rare bird species and improving soil health within five years.
- Animal population management combined with wildlife tourism created an income stream, revitalizing the estate's finances.
- Inspired by their success, hundreds of thousands of acres across the UK are now undergoing rewilding.
- Isabella Tree rewilded her acre-sized walled garden, previously a monoculture lawn, increasing biodiversity by 35% in just three years.
- The first step is creating uneven terrain, such as mounds and hollows, for varied microclimates.
- Second, choose plants that specifically support insects and pollinators.
- Third, emulate herbivores by preventing any single plant from dominating, and 'find life in death' by leaving dead wood, leaves, and seed heads for habitat and fertilizer.
- Private gardens in the UK cover an area significantly larger than national nature reserves, representing vast potential for biodiversity.
- Examples of rewilding efforts in urban and public spaces include a wildflower meadow at the Tower of London and revitalized green space at the Field Museum in Chicago.
- Rewilding requires a shift in aesthetic, embracing the messy and unpredictable aspects of nature, and a relinquishing of absolute control.
