Scientists have created an interactive global map detailing the vastness of underground fungal networks, which they equate to a biological “wood wide web.” This extensive network, composed of fungal filaments called hyphae, plays a critical role in ecosystem health and plant life, according to research published last July.<\/p>\n
The study estimated that the fungal filaments within the top 15 centimeters of soil stretch approximately 62 quadrillion miles. This length is so immense that if spun into a single strand, it could theoretically extend from the Earth to the Sun and back one billion times. The interactive map allows users to visualize the density of these biological networks across various global ecosystems.<\/p>\n
These fungal networks, particularly arbuscular mycorrhizal fungi, form symbiotic relationships with plants. Plants provide sugars produced through photosynthesis, while fungi supply essential nutrients like phosphorus and nitrogen, along with water. This partnership is crucial for maximizing plant carbon storage potential. The research indicates that fungal network density is significantly reduced in areas of intensive human agriculture.<\/p>\n
While often referred to as the “wood wide web,” the greatest density of these networks is found in grasslands and wetlands, with notable hotspots including the Anatolian steppe, Tibetan plateau, parts of the North American Prairie, the Everglades, and the Sudd wetlands in Africa. This is partly because their extensive reach into the soil complements the shallower root systems of grassland plants, unlike forests where tree roots delve deeper.<\/p>\n
The scientists, affiliated with the Society for the Protection of Underground Networks (SPUN), argue that fungi are a blind spot in current global conservation strategies. Their research indicates that less than 10% of the densest fungal network clusters are currently located within officially protected areas. Furthermore, of the thousands of species involved in these networks, very few have been assessed for endangered status by the International Union for Conservation of Nature.<\/p>\n
SPUN advocates for the inclusion of fungal populations and network density in the designation of conservation areas. The newly developed map is intended to help identify regions where these vital underground networks require greater protection and restoration efforts. The scientists aim to use this data to bolster the global conservation goal of protecting 30% of land in perpetuity for ecosystem integrity.<\/p>\n","protected":false},"excerpt":{"rendered":"
