Tree Communication: A Natural Phenomenon Explored
Suzanne Simard's Mother Tree Project: A Vision for Sustainable Forestry
Suzanne Simard's Mother Tree Project is a groundbreaking long-term ecological research initiative that seeks to understand and preserve the complex underground fungal networks connecting trees, particularly focusing on "mother trees." This project, conducted in multiple regions of British Columbia, aims to find more ecologically sound forest harvesting methods and better understand forest resilience to disturbances and climate change.
The project contrasts traditional clearcutting methods—which completely remove large patches of trees, destroying these fungal networks and the knowledge embedded in mother trees—with more selective and less destructive approaches. For instance, the project is investigating the impacts of the European cut-to-length system, which allows loggers to selectively fell trees and cause less damage to the remaining forest. Initial results from trials suggest that this method causes less ecological damage compared to clearcutting, by preserving more standing trees and maintaining fungal connections.
The Mother Tree Project spans nine forests of Douglas fir, covering an area about the size of Denmark. It includes a climate gradient along the border with the U.S. and Canada, from the 49th parallel up to about the 57th parallel. The project compares the effects of clear-cut logging with other sylvan culture systems to understand the impact on carbon pools, soil biodiversity, and wildlife.
Suzanne Simard, a renowned ecologist, grew up in massive old-growth forests and comes from a family of horse loggers, which has significantly influenced her perspective on forest management. Her spiritual connection to forests is rooted in her upbringing, and she views forests as communities of interdependent species, rather than individual trees competing for resources.
Simard's research has significantly altered our understanding of forests, revealing the existence of a vast below-ground network of mycorrhizal fungi used by trees for communication and resource exchange. This network is essential to a forest's health, with mother trees acting as central hubs, supporting younger seedlings by sharing nutrients and information through these networks.
Simard's vision is one of forests healing and people working together to stand them back up, as a symbol of a resilient future. She believes that it is a choice for humanity to create a future where people live in harmony with the land and forests, reducing suffering and creating abundance. This vision has inspired various works of art, including the movie "Avatar" and Richard Powers' novel "The Overstory."
The Mother Tree Project is a 100-year project, with potential for future generations to continue the work. Simard collaborates with Indigenous communities and scientists in British Columbia to learn about traditional forest management practices, aiming to create a future where forests and people can thrive together.
However, Simard's spiritual approach to forestry has been met with criticism from reductionist scientists. Nevertheless, her work continues to challenge the dominant paradigm in forestry, which emphasizes managing forests like tree farms for economic gain, and to inspire a new vision for sustainable forestry.

- Suzanne Simard's Mother Tree Project, a long-term ecological research initiative, seeks to understand and preserve intricate underground fungal networks in forests, focusing on mother trees and their roles in environmental-science, particularly regarding climate-change resilience.
- The project contrasts traditional clearcutting methods, which cause extensive damage to these fungal networks and the rest of the forest ecosystem, with selective approaches such as the European cut-to-length system, which causes less ecological harm.
- The Mother Tree Project investigates the impacts of various forest management practices on carbon pools, soil biodiversity, and wildlife, and it is conducted across diverse regions of British Columbia, including areas with varying climates.
- Suzanne Simard's vision for sustainable forestry encompasses forests as resilient, interdependent communities of species and centers on the idea of humans living harmoniously with nature, promoting sustainable-living, home-and-garden practices that respect the environment.
