Estimating carbon sequestration in the Pacific Northwest

Mean net ecosystem production in the U.S. Pacific Northwest

Mean net ecosystem production for 2006-2010 (from Turner et al., 2016).

Net ecosystem production (NEP) for the 2006–2010 interval on Pacific Northwest forestland reveals an overall carbon sink throughout the region.

How will climate change shift the tundra - taiga interface?
