Fungal Ethnoecology: Observed Habitat Preferences and the Perception of Changes in Fungal Abundance by Mushroom Collectors in Poland

Summary

This research examined how mushroom collectors in Poland understand and describe where different mushrooms grow and how mushroom populations have changed over time. The study reveals that local mushroom collectors have detailed knowledge about mushroom habitats that sometimes exceeds scientific understanding. Most notably, collectors have observed a concerning decline in mushroom abundance, mainly due to increasing drought conditions. Impacts on everyday life: – Helps preserve traditional knowledge about mushroom habitats that could be lost as older generations pass away – Provides early warning signs about environmental changes affecting wild mushroom populations – Demonstrates how citizen observations can contribute to scientific understanding and monitoring of nature – Highlights the importance of considering local knowledge in forest management and conservation – Shows how climate change is affecting food resources that many people traditionally gather

Background

Scientists frequently raise concerns about data deficiency related to the abundance and distribution of macrofungi in the context of climate change. Traditional ecological knowledge from local communities can provide valuable insights about fungal ecology and habitat preferences that complement scientific understanding.

Objective

To document habitat types used by local Polish mushroom collectors to describe fungal habitat preferences, document habitat preferences of specific mushroom species based on collector observations, analyze local perception of macrofungal population trends, and generate hypotheses for further research based on these observations.

Results

The study documented 98 different habitat types used by collectors to describe fungal habitats. For 35 fungal taxa, detailed habitat preferences were compiled based on multiple independent observations. Most respondents (53%) observed a decrease in macrofungi abundance during their lifetime, with drought being the main reported cause. Only one species, Imleria badia, showed increased abundance according to multiple independent reports.

Conclusion

Polish mushroom collectors demonstrated deep understanding of fungal habitats, using different habitat scales to describe preferences. Some ecological phenomena they observed have not yet been studied scientifically. The unanimous perception of decreasing fungal abundance, with drought as the key driver, suggests local ecological knowledge could contribute to citizen-based monitoring of macrofungi and generate new research directions.
