Researchers in Brussels will collect 10,000 samples of underground fungal networks over the next 18 months from around the world, using machine learning to seek out the most biodiverse hotspots and map global fungal networks. By creating thread-like webs in soil that suck in CO2 and transport nutrients like phosphorus to plants, these underground fungal networks are necessary for the health of plants, trees and larger ecosystems. The researchers hope to use the information gathered on these hotspots to better protect natural ecosystems and store carbon dioxide to help tackle climate change. The project is funded by a $3.5 million donation from the Jeremy and Hannelore Grantham Environmental Trust.
