Soil Fungi Act like a Support Network for Trees, Study Shows

Being highly connected to a strong social network has its benefits. Now a new University of Alberta study is showing the same goes for trees, thanks to their underground neighbours.

The study, published in the Journal of Ecology, is the first to show that the growth of adult trees is linked to their participation in fungal networks living in the forest soil.

Though past research has focused on seedlings, these findings give new insight into the value of fungal networks to older trees–which are more environmentally beneficial for functions like capturing carbon and stabilizing soil erosion.

“Large trees make up the bulk of the forest, so they drive what the forest is doing,” said researcher Joseph Birch, who led the study for his PhD thesis in the Faculty of Agricultural, Life & Environmental Sciences.

When they colonize the roots of a tree, fungal networks act as a sort of highway, allowing water, nutrients and even the compounds that send defence signals against insect attacks to flow back and forth among the trees.

Why Healthy Soil Means A Healthier Planet

Dirt, it turns out, has been underestimated. Healthy soil is perhaps the most essential part of a thriving ecosystem. In the face of climate change, farmers and scientists are working to better understand how soil supports a healthy planet. It turns out that without it, the rest of an ecosystem suffers.

Soil is composed of various materials, including sand, silt, stone and water. Depending on the geographic location, it can be sandy, dense, rocky or porous. Soil is a living thing and composed of millions of tiny organisms that help keep it healthy. Different types of insects, bacteria and fungi all work together to keep things in balance. Fungal networks, known as mycelium, play a vital role in helping dirt communicate with plant roots. In fact, the largest known organism in the world is a fungus that covers 4 square miles of forest in the Pacific Northwest.

Modern farming practices, land development and pollution are threatening the health of our planet.

Restoring Soils Could Remove up to ‘5.5bn Tonnes’ of Greenhouse Gases Every Year

Replenishing and protecting the world’s soil carbon stores could help to offset up to 5.5bn tonnes of greenhouse gases every year, a study finds.

This is just under the current annual emissions of the US, the world’s second largest polluter after China.

Around 40% of this carbon offsetting potential would come from protecting existing soil carbon stores in the world’s forests, peatlands and wetlands, the authors say.

In many parts of the world, such soil-based “natural climate solutions” could come with co-benefits for wildlife, food production and water retention, the lead author tells Carbon Brief.

Ground up

The top metre of the world’s soils contains three times as much carbon as the entire atmosphere, making it a major carbon sink alongside forests and oceans.

Soils play a key role in the carbon cycle by soaking up carbon from dead plant matter. Plants absorb CO2 from the atmosphere through photosynthesis and this is passed to the ground when dead roots and leaves decompose.

SANTIAGO, Chile – November 11, 2019 – In a show of solidarity with the growing Regeneration Movement in Chile and throughout Latin America, Regeneration International today announced it will hold the regeneration network’s annual general assembly and related global climate events in Santiago and regions, as planned, despite the recent announcement that Chile has pulled out of hosting the COP25 Global Climate Summit.

Regeneration International and key partners will also send delegations to the official COP25, which has been relocated to Madrid. 

“This is a historical and deeply symbolic moment for Chile,” said Ercilia Sahores, Regeneration International Latin America director. “Our decision to proceed with the meetings we’ve spent months organizing on the ground with Latin American civil society organizations reflects our commitment to ensuring that citizen voices, not just institutional voices can join forces and have a platform at COP25. We believe that the Regeneration Movement offers hope, in the way of practical, environmental, socioeconomic and political solutions to the systemic crisis occurring now in Chile and other parts of the world.”

“Regeneration International is inspired and energized by the unprecedented upsurge of grassroots resistance and regeneration spreading across the globe, said Ronnie Cummins, Regeneration International co-founder and steering committee member. “The recent uprisings in Chile, Hong Kong, Moscow, Lebanon and other nations, and the rapid growth of the Sunrise and Extinction Rebellion movements in the U.S. and Europe, are calling for system change as the only way to address the Climate Emergency and the related political, social and economic crises bearing down upon us. Regeneration International and our allied NGOs look forward to traveling to Santiago in December to participate with our Chilean and Latin American partners in building up a strong network throughout the Americas for a transcontinental Green New Deal with a strong focus on regenerative food, farming, reforestation and ecosystem restoration.” 

“The time we expected has arrived, years of training and active experimentation for eco-social regeneration in our hands, hearts and minds,” said Javiera Carrión, co-founder of El Manzano Permaculture, a Regeneration International affiliate. “The context has changed rapidly and violently here in Chile, as is happening in other parts of the world“. These are interesting and uncertain times. It is also time for the Regeneration Movement to gather and re-strategize. We have much work to do, and are grateful to have the support of Regeneration International at this critical moment.”

“Savory is excited to join forces with Regeneration International,” said Daniela Howell, CEO of the Savory Institute,” in both Chile and Spain during COP25, with our Hub leaders in South America and Europe joining in an expression of our committed support to the regenerative movement in these regions and globally. We look forward to participating as a united front in key sessions to advance the support for regenerative agriculture and the global 4×1000 initiative, as well as shared time of inspiration and friendship.”

Regeneration International will hold its General Assembly in Santiago December 9-10.

Regeneration International is a 501(c)(3) nonprofit dedicated to promoting, facilitating and accelerating the global transition to regenerative food, farming and land management for the purpose of restoring climate stability, ending world hunger and rebuilding deteriorated social, ecological and economic systems.
