A review of 263 papers reveals that arbuscular mycorrhizal fungi (AMF) play a major role in restoring tropical forests by boosting nutrient cycling, soil structure, and plant resilience. These fungi form symbiotic relationships with over 80% of tropical plant species, improving phosphorus uptake and increasing survival in degraded areas. The review also highlights a major research gap: most restoration projects still overlook fungi entirely. If we want to regenerate ecosystems faster and more sustainably, AMF should be part of the plan.
