Study Site: Saskatchewan
Purpose: The boreal biome accounts for approximately one third of the terrestrial carbon (C) sink. However, estimates of its individual C pools remain uncertain. Here, focusing on the southern boreal forest, we quantified the magnitude and temporal dynamics of C allocation to aboveground tree growth at a mature black spruce (Picea mariana)-dominated forest stand in Saskatchewan, Canada. We reconstructed aboveground tree biomass increments (AGBi) using a biometric approach, i.e., species-specific allometry combined with forest stand characteristics and tree ring widths collected with a C-oriented sampling design. We explored the links between boreal tree growth and ecosystem C input by comparing AGBi with eddy-covariance-derived ecosystem C fluxes from 1999 to 2015 and we synthesized our findings with a refined meta-analysis of published values of boreal forest C use efficiency (CUE).
Abstract: The Southern Old Black Spruce (OBS) study site in Saskatchewan consists of a Picea mariana master ring width measurements collection (cana610.rwl), and ring width measurements at two sub-plots established in the field (cana610.plota.rwl and cana610.plotb.rwl). The subplot collections consist primarily of black spruce (core ID's 'PM'), but also contain a few samples of Larix laricina (core ID's 'LL'). NOAA Template Raw Measurements file added 2020-07-07.
