About SPUN

SPUN is a non-profit, science-based initiative founded to map fungal networks and advocate for their protection. In collaboration with researchers and local communities, we aim to accelerate efforts to protect the underground ecosystems largely absent from conservation and climate agendas. We propose that fungal networks—and the services they provide—are a global public good, analogous to clean air and water.

Our Mission

Map the fungal networks that help regulate the earth’s climate and ecosystems, and advocate for their protection

Scientific rigor

Advocate for change based on rigorous science.

Open data

Make all data publicly available and accessible.

Inclusive action

Build a diverse network of researchers and local communities.

Dr. Toby Kiers

Toby Kiers is a Professor of Evolutionary Biology and University Research Chair at Vrije Universiteit Amsterdam. Her lab uses nanoprobes and high-resolution imaging to map the nutrient flows and architecture of plant-fungal networks. She is globally-recognized for her scientific work in the evolution of symbiotic trade, and her public outreach activities, including a 2019 TED talk. Kiers won an Ammodo Award in 2019 for “unfettered science”, and was awarded the E.O. Wilson Award for Natural History in 2021.

Dr. Colin Averill

Colin Averill is a Senior Scientist at ETH Zürich where he and his team study the forest microbiome – how does microbial diversity affects which trees live in a forest, carbon sequestration, and climate change forecasts? He has won multiple awards from the Ecological Society of America, and held a NOAA Climate and Global Change Fellowship to incorporate global microbiology into climate change. He currently sits on the scientific advisory boards of global ecosystem restoration initiatives Plant for the Planet and RESTOR.
