The life of the forest. Fungi
Forest Film Studio・14 minutes read
Forests are complex ecosystems where fungi play a significant role in converting energy and carbon dioxide into biomass, with an estimated 5 million diverse species globally. Fungi, both beneficial and pathogenic, are crucial for ecosystem functioning and require preservation to maintain biodiversity and ecological balance.
Insights
- Fungi, with over 5 million species globally, have diverse fruiting bodies and play vital roles in forest ecosystems, from decomposing organic matter to forming symbiotic relationships with plant roots for nutrient exchange and protection from pathogens.
- Human activities, including overexploitation of forest resources and improper management practices, threaten fungal diversity in forests, leading to dieback and habitat loss for symbiotic fungi, highlighting the importance of preserving forest ecosystems to maintain fungal biodiversity and overall ecosystem health.

Recent questions
What role do fungi play in forest ecosystems?
Fungi play a significant role in forest ecosystems by breaking down dead wood, creating ecological niches for other species, forming symbiotic relationships with plant roots, aiding in nutrient exchange, and protecting against pathogens. They contribute to ecosystem functioning and biodiversity.
How do fungi impact tree health in forests?
Fungi can impact tree health in forests by attacking plants as pathogenic fungi, leading to dieback and extinction in some cases. Trees like oaks, ashes, and elms are threatened by fungal pathogens, emphasizing the importance of protecting forests to preserve tree species.
Why is preserving fungal biodiversity crucial for forests?
Preserving fungal biodiversity is crucial for forests because fungi are essential for ecosystem functioning, nutrient cycling, and maintaining biodiversity. Managed forests serve as indicators of ecosystem changes due to human activities, highlighting the importance of protecting fungal diversity.
What are the threats to fungal diversity in forests?
Threats to fungal diversity in forests include overexploitation of forest resources, improper forest management practices, changing climate conditions leading to forest dieback, and habitat loss for symbiotic fungi. These factors pose risks to the diversity of fungi and overall forest health.
How do foreign fungi species impact native ecosystems?
Foreign fungi species, introduced to Europe from distant lands, can impact native ecosystems and species of fungi. Mass collections of foreign fungi by mushroom pickers contribute to their spread to new areas, emphasizing the need to understand and preserve the complex forest ecosystem where fungi play a crucial role.

The Importance of Fungi in Forest Ecosystems
- Forests are complex ecosystems where various organisms interact, converting solar energy and carbon dioxide into biomass.
- Fungi, a crucial group in forest ecosystems, play a significant role in ecosystem functioning.
- Fungi are incredibly diverse, with an estimated 5 million species globally, and produce a wide variety of fruiting bodies.
- Fungi can have different fruiting body shapes and colors, ranging from white to dark brown, with various forms of hymenophore.
- Fungi, like velvet shanks and common morels, have specific fruiting periods and preferences for decomposing organic matter.
- Fungi, including bracket fungi, help break down dead wood, creating ecological niches for other species.
- Pathogenic fungi can attack plants, affecting forest ecosystems, especially in human-influenced forests like those experiencing oak dieback.
- Trees like oaks, ashes, and elms are threatened by fungal pathogens, leading to dieback and extinction in some cases.
- Mycorrhizal fungi form symbiotic relationships with plant roots, aiding in nutrient exchange and protection against pathogens.
- Protecting forests is crucial for preserving fungal biodiversity, with managed forests serving as indicators of ecosystem changes due to human activities.

Restoring Forests: Fungi's Vital Role
- To support the newly created forest, the young generation of the forest takes care of its fungi, emphasizing the importance of restoring forests quickly and introducing diverse tree species to create niches for hundreds of fungal species.
- Forest trees are obligatorily mycorrhizal species, requiring association with mycorrhizal fungi for proper growth, highlighting the significance of high colonization by diverse mycorrhizal fungi in tree seedlings for efficient planting and afforestation.
- The overexploitation of forest resources and improper forest management practices, such as simplifying forest structure and species composition, pose threats to the diversity of fungi, exacerbated by changing climate conditions leading to forest dieback and habitat loss for symbiotic fungi.
- Foreign fungi species, like the octopus stinkhorn and matte Jack from distant lands, have been introduced to Europe, impacting native ecosystems and species of fungi, with mass collections of Aureoboletus projectellus by mushroom pickers contributing to its spread to new areas, emphasizing the need to understand and preserve the complex forest ecosystem where fungi play a crucial role.
