About SPUN

SPUN (Society for the Protection of Underground Networks) is a scientific research organization that maps mycorrhizal fungal communities and advocates for their protection. It runs programs like the Underground Atlas to visualize biodiversity hotspots and assess protected status of subterranean fungal networks, and it collaborates with researchers and local communities through expeditions such as Underground Explorers. The organization operates globally, with a focus on soil biology, mycorrhizal fungi, and ecosystem health. SPUN also publishes explainers, peer‑reviewed papers, and field protocols to advance understanding of underground biodiversity.
