Healthy forests are essential for healthy coral reefs. When forests disappear, sediment, nutrients, and polluted runoff flow into the ocean, smothering corals and reducing water clarity. Reforestation stabilises soil, filters water, restores natural hydrology, and reduces nutrient overload — giving coral reefs the chance to recover. In Bali, restoring forests upland directly supports the reefs below.

Our work at Restore the Legacy shows that mycorrhiza is essential for restoring healthy tropical forests in Bali and Borneo. In this article, we explain how these underground fungi improve soil health, boost tree growth, and strengthen ecosystem resilience.
