A study published in Science on June 11 estimates that there are approximately 110 quadrillion kilometers of arbuscular mycorrhizal fungal networks underground, which, if connected, would stretch nearly a billion times the distance from the Earth to the sun. These networks form symbiotic relationships with plant roots, providing essential nutrients while sequestering about 1 billion tons of carbon annually. The research, led by the Society for the Protection of Underground Networks (SPUN), utilized literature reviews, soil samples, machine learning, and laboratory testing to map the distribution and density of these fungal systems globally. The study highlights the importance of these networks in supporting plant growth and carbon storage, while also noting that fungal densities in agricultural areas are significantly lower than in wild ecosystems. The findings indicate that 90% of fungal communities worldwide are unprotected, and the researchers plan to present their work at the upcoming United Nations Climate Change Conference (COP31) to emphasize the ecological significance of these networks.

Research Maps Global Distribution of Mycorrhizal Fungal Networks
A recent study published in Science has mapped the global distribution of arbuscular mycorrhizal fungal networks, estimating their length to be 110 quadrillion kilometers. These networks play a crucial role in nutrient exchange with plants and carbon sequestration, but they are under threat, particularly in agricultural areas. The research team will present their findings at COP31 to highlight the importance of protecting these ecosystems.
