Australia is the natural home of macadamias, and the only place on earth where they grow wild. Every commercial macadamia crop in the world can be traced back to the wild macadamia trees that still grow in the Australian rainforest. But over the last two centuries, more than 80% of wild macadamias have been lost, posing ongoing threats to their populations. All four precious wild macadamia species are endangered, but thanks to a new National Recovery Plan to guide their protection, their future is now looking more positive.
