Forests are resilient, but their recovery from disturbance or destruction can take decades—or even centuries. As the world faces great challenges from deforestation and habitat loss, many are asking: Can we do more to help forests heal?
Enter the fungal miracle. Recent research and innovative land stewardship practices are revealing how fungi—those often-overlooked organisms beneath our feet—can play a starring role in accelerating forest regeneration. By restoring the intricate web of life in the soil, fungi can nurture seedlings, rebuild healthy ecosystems, and kickstart the recovery of the world’s woodlands at a pace once thought impossible.
HAVE YOU HEARD ABOUT MYCOFORESTRY?
Mycoforestry is a branch of science concerned with the wonderful symbiosis between the fungal and vegetal worlds: the underground hyphal network called mycorrhizal association. Because plants are strongly connected through a mycelial net, we observe fluid communication, even nutrient distribution, and improved forest health.
Why is that?
Fungi colonize a host plant’s root system, increasing water and nutrient absorption, while the plant provides the fungus with carbohydrates produced through photosynthesis. Mycorrhizae also offer the host plant increased protection against certain pathogens.
Approximately 90% of all vascular land plants live peacefully in some association with mycorrhizal fungi. Mycorrhizal associations also appear in the fossil record and are believed to have helped early land plants conquer land.
What we see is a highly competitive way to thrive on Earth among diverse living organisms.
Reforestation efforts are greatly enhanced when mycorrhizae are introduced to sprouting seeds or to the roots of young trees before or at the time of planting.
The value of fungi is increasingly recognized amid serious losses of habitats and biodiversity, driven mainly by human deforestation and land abuse.
To help nature recalibrate after a major loss, fungi must be brought into close contact with the dead wood so that the forest floor can act as a springboard for saprophytic and other fungi, which are instruments of the forest’s immune system, ready to heal its wounds. For several years after a forest has been cut, the mycosphere survives underground, with diversity steadily declining unless plant communities and debris fields are renewed.
Can reforestation be a small-scale intervention?
Absolutely yes. We tend to think that to act against such massive disasters we need to operate at tremendous scales, like within globally organized networks. The truth about the fungi world is that spore dispersal already works this way. Globally.
Spores can travel several thousand kilometers using a natural jet-stream force and can rest in dormancy for centuries, and probably more.
By inoculating spores of known fungi species that benefit a specific tree or multiple tree species, we speed up the growth of individual plants and, in turn, the rehabilitation of entire forests. I recommend creating a matrix by chipping wood into variably sized fragments so mycelium can quickly grab and invade the wood. Wood fragments with greater surface area are more likely to contact spores or mycelium; this is especially true in mushroom cultivation, where spawn growth is integral to success.
As follows are some suggested practices and rules from the Agroforestry guidelines:
- Use native fungal species in habitats needing restoration.
- Select species known to help plant communities
- Select mushroom species that attract insects whose larvae are food for fish and birds
- Select fungal species according to their interactions with bacteria and plants
- Choose species of known medicinal or culinary value if economically valuable mushrooms help tilt the balance in favor of preservation
- If you are not confident about the practice, learn more
