This kind of design, where one element does many jobs and the jobs reinforce each other, seems to be nature’s signature approach. It’s how healthy systems work. And increasingly, it’s how the most successful ecological restoration works. When you restore a degraded landscape by reintroducing the right elements, trees, soil bacteria, water flows, you’re not just fixing one problem. You’re restoring multifunctionality, and that multifunctionality creates cascading benefits that spread through the system. Rewilding efforts demonstrate multifunctionality. When wolves were reintroduced to Yellowstone, they reduced deer populations that had been overgrazing young trees. With more trees able to grow, beavers had the materials to build natural dams. Those dams created wetlands that recharged aquifers and changed the course of rivers, providing more water for the whole forest system. The wolves weren’t just controlling deer, they were part of a chain of operations affecting trees, water, soil, and the entire landscap…
