Robert and Robyn Guyton have planted a 'Food Forest' around their house in Riverton, Southland so no lawns need to be mowed and in season, the forest is dripping with organic fruit and nuts. The Guytons have several other local projects on the go too, from saving heirloom seeds and developing a community garden, to restoring the Te Wai Korari Wetland Reserve along the Jacob's River Estuary.
