From the video's description, “In the small town of Riverton at the bottom of New Zealand's South Island is Robert and Robyn Guyton's amazing 23-year-old food forest. The 2-acre property has been transformed from a neglected piece of land into a thriving ecosystem of native and exotic trees where birds and insects live in abundance. Robert and Robyn are a huge inspiration to us, not only for their beautiful approach to healing the land and saving heritage trees and seeds, but for the way they've impacted on their local community.”
