Rewilding Surfing
Back in 1995, when Kelly Slater had hair, boardshorts were made from sails, and grommets suffered abuse, Grey Wolves were reintroduced in Yellowstone. They soon controlled overabundant elk and allowed native trees to recover, which in turn stabilised riverbanks and led to the return of songbirds and other native species.
More recently, beavers have been dropped in all over the USA, and have improved freshwater storage, boosted biodiversity and helped contain wildfires. As the old saying goes; The power of the beaver is strong.
