Society for the Protection of
Underground Networks


SPUN is to dedicated to the protection of global fungal networks through the conservation of underground ecosystems.

Every year, roughly 5 billion tons of carbon are transferred from plants to underground mycorrhizal networks.

These networks – which evolved 450 million years ago – form a fundamental link between plants roots and our global soils, and represent a key component of underground carbon storage.

Logging, fire, and mechanical tillage destroy the diversity, integrity, spread, and survival of mycorrhizal networks.
