A groundbreaking study led by Dr. Sabrina Trivedi from the Society for the Protection of Underground Networks (SPUN) has unveiled the critical importance of mycorrhizal fungi — tiny organisms forming vital underground partnerships with plants worldwide. By analyzing over two billion fungal DNA samples from 130 countries, the team created detailed global maps showing that more than 90% of these essential fungal biodiversity hotspots fall outside current protected areas. This leaves these underground networks highly vulnerable to habitat destruction and climate change.
These fungi play a crucial role in maintaining healthy ecosystems by cycling nutrients, supporting plant growth, and sequestering over 13 billion tons of carbon dioxide annually — roughly one-third of emissions from fossil fuels. Despite their importance, fungal ecosystems, or “funga,” have been largely overlooked in conservation efforts. Researchers warn that neglecting these hidden networks could disrupt forest recovery, reduce crop yields, and threaten biodiversity. To help address this, SPUN has launched an interactive “Underground Atlas” to guide policymakers in identifying and protecting critical fungal habitats. The study highlights the urgent need to include fungi alongside plants and animals in global conservation strategies to safeguard ecosystems and combat climate change. More
