Taiwan's Hidden Giant Forests: What They Reveal About Fungi and Climate Change

Summary: A Lost Forest in Taiwan's Mountains

Scientists have discovered an extraordinary forest in the remote, steep mountain regions of Taiwan: hundreds of giant Taiwan cedars (Taiwania cryptomerioides), including one specimen measuring 84.1 meters—the tallest known tree in East Asia. The expeditions, which spanned years, combined LiDAR mapping, citizen science, and detective-like meticulous work. Researchers speak of "temples of giants," as dozens of these ancient forest titans stand close together. These forests are among the most carbon-rich ecosystems in the world—and this is exactly where the topic of fungi and climate change comes into play: the underground fungal cycle plays a crucial role in the growth and resilience of such forests.

The original report was published on August 2, 2026, on ScienceDaily (see sources). This article is an editorial summary and analysis from a fungal ecology perspective.

Fungi and Climate Change: Why Ancient Forests Are Important Allies

The newly discovered forests in Taiwan are remarkable not only for their trees but also for their contribution to the global carbon budget. Trees store carbon in their biomass—but a large portion is also locked in the soil, bound through complex fungi-tree interactions. Mycorrhizal fungi, which live in symbiosis with the roots of the cedars, transport nutrients and water, extend the root system, and help trees survive dry periods. At the same time, they act as a carbon sink: they deposit organic material in the soil that would otherwise be released as CO₂. In Taiwan's "lost" forests, these fungal networks may have grown over centuries, contributing to the exceptionally high carbon stocks.

However, climate change is altering the conditions for these fungi. Rising temperatures and changing precipitation patterns are shifting the habitats of many species. In our latitudes, we already observe that some fungal species fruit earlier in the year (phenology) and that warmth-loving species are migrating northward. These changes are not only relevant for mushroom foragers but also for forest health: when fungal networks are weakened, trees can absorb less water and nutrients, making them more vulnerable to drought and pests. Taiwan's giant forests offer a unique opportunity to study such relationships in a still largely undisturbed ecosystem.

The Role of Mycorrhizal Networks in Carbon Sinks

For climate research, it is crucial to know how much carbon a forest actually stores—above and below ground. The newly mapped forests in Taiwan could serve as a model to quantify the contribution of fungi. Studies show that mycorrhizal fungi can be responsible for up to a third of the carbon bound in soil. They stabilize soil aggregates, promote humus formation, and protect organic material from microbial decomposition. In the dense "temples of giants" with their hundreds of ancient trees, these processes are likely to be particularly effective.

At the same time, such ecosystems are fragile: disturbances such as logging or extreme weather events—which are becoming more frequent due to climate change—can destroy fungal networks and release stored carbon. Therefore, it is important to protect not only the trees but also the invisible soil life. Citizen science projects and modern mapping techniques, such as those used in Taiwan, can help identify such hotspots.

What Does This Mean for Mushroom Foragers and the FungiFind App?

Even though Taiwan's giant forests are far away, the findings have direct implications for our local forests and mushroom growth. Climate change is shifting not only the distribution ranges of fungi but also their fruiting times. Species like the sheathed woodtuft (Kuehneromyces mutabilis) now often fruit earlier or later in Central Europe than they did decades ago. With the FungiFind mushroom map, you can observe and document such changes in your region. The app shows where mushrooms are currently reported and helps identify patterns related to weather data.

The weather score—which we regularly present on the blog—evaluates how favorable conditions are for mushroom growth based on temperature, humidity, and precipitation. In times of climate change, this prediction becomes increasingly important, as extreme weather such as droughts or heavy rain makes the mushroom season unpredictable. The FungiFind species lexicon also provides information on many species, including their ecological requirements—so you can better understand why some mushrooms suddenly appear elsewhere or not at all.

Conclusion: Fungi as Indicators and Allies in Climate Change

The discovery of the giant forests in Taiwan is a fascinating example of how little we still know about the complex ecosystems of our planet. But it also shows how closely trees, fungi, and climate are intertwined. Fungi and climate change are not a contradiction but a unity: fungi respond sensitively to changes, and they can help us understand and perhaps even mitigate the impacts of climate change—for instance, through their role as carbon sinks.

For us at FungiFind, this means: we want to make these connections visible—through observations, data, and education. The next time you stroll through the forest, remember: beneath your feet, a vast network is working to keep the forest alive. And with your help, we can better understand how it is doing.
