Taiga
Boreal forest, Alaska, U.S., dominated by spruce trees (Picea).
The taiga, or boreal forest, is a critical component of Earth's carbon cycle because it serves as a massive terrestrial carbon sink. Its importance in storing carbon stems from two primary factors:12
- Biomass Storage: The taiga contains a significant portion of Earth's total biomass. A large amount of carbon is sequestered directly within the tissues of the coniferous trees and other vegetation that make up these vast forests.12
- Soil and Permafrost: The ecosystems and soils of the boreal region store vast quantities of carbon in the form of dead, undecomposed, or partially decomposed organic matter. Much of this carbon is locked away in permafrost, where cold temperatures have preserved organic material for thousands of years.134
Together with the tundra, the taiga accounts for approximately one-third of global soil carbon storage. However, this carbon is vulnerable; global warming and land-use changes can accelerate decomposition or trigger fires, potentially releasing this stored carbon back into the atmosphere as carbon dioxide or methane, which would further exacerbate climate change.315
