Description:55.880° N, 98.481° W, elevation of 259 m, Boreal coniferous: Black spruce; occasional larch present in poorly-drained areas. Groundcover is moss (feathermosses and Sphagnum), Labrador Tea, Vaccinium, and willows are a main component of the understory. It was established in 1993 as a BOREAS site.
Acknowledgments:The data collection was funded by many sources, including: the DOE Terrestrial Carbon Program, NASA Terrestrial Ecosystem Program, the Fluxnet Canada Research Network and the Canadian Carbon Program (supported by the Canadian National Science and Engineering Research Council (NSERC), the Canadian Foundation for Climate and Atmospheric Sciences and the BIOCAP Canada Foundation).
