peatlands
Peatlands are waterlogged wetland ecosystems where incomplete decomposition of plant material leads to the accumulation of thick layers of organic-rich peat over thousands of years. They represent a critical intersection of plant biology and carbon cycling, as the slow breakdown of plant litter under anoxic conditions effectively locks away vast stores of carbon. Understanding the plant communities that drive peat formation — and how they respond to environmental change — is essential for predicting ecosystem stability and the fate of globally significant carbon reserves.

Canadian researchers built a detailed, nationwide map of soil, rock, and peatland water-holding properties to better model how water moves through the landscape — from rainfall down through the ground and into rivers and streams.
The dataset covers all Canadian provinces and territories at 250-meter resolution, organized into 7 underground layers with the top two spanning 0–1 meter below the surface.
Peatlands were classified into three decomposition levels (moderately, decomposed, and well-decomposed peat), each with different water-storage properties critical for wetland ecosystems.
The final product is an 18-band raster map integrating mineral soils, bedrock outcrops, and peatlands — extending into shared watersheds with the United States for cross-border water modeling.
