Forester and scientist Suzanne Simard is well known for her landmark 1997 paper, which demonstrated that two distinct species of trees could share resources. At the time, it turned traditional Western forestry thinking on its head. Instead of the Darwinian view of trees as being in competition with each other, it introduced the idea that these trees may actually help each other, and that industrial logging practices may be missing the forest for the trees.

In recent years, Simard has been advocating for Indigenous knowledge as the only way to save the Earth and its forests. Environmental reporter Erica Gies spent some time in the field with Simard and her colleagues, looking into her latest project, The Mother Tree Project, which seeks to find the most sustainable form of forestry for both people and ecosystems.

Gies joins the Mongabay Newscast to explain what she learned from Simard and why she advocates Indigenous knowledge and systems, which are governed by rules of reciprocity. A shift in her thinking occurred when she read the dissertation of fisheries ecologist Teresa Sm'hayetsk Ryan, who now works with Simard.

"She realized that, you know, the people were also a very important part of the complex forest relationships," Gies says. "Which is much more of a reciprocity kind of mentality. If you take, you also give back. There is a responsibility to care for the system. Because if you don't, and if you overexploit it, it would be really easy to starve, right?"
