Australia gave the world the macadamia. Now the wild trees are disappearing.
Macadamias evolved here millions of years ago and were tended by First Nations peoples for tens of thousands of years. Today, over 80% of wild macadamia habitat has been cleared. The trees grown for their nuts are thriving – but the original wild trees are struggling to survive. Wild Macadamia Conservation exists to protect them and the rich biodiversity of the sub-tropical forests they call home.
