The associated NCEI study type is Tree Ring. The data include parameters of tree ring with a geographic location of Saskatchewan, Canada. The time period coverage is from 56 to -65 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data. Tree ring data from the International Tree Ring Data Bank and World Data Center for Paleoclimatology archives. Most data sets include raw treering measurements (most are annual ring width, with some collections of earlywood or latewood width or wood density), plus chronologies (standardized growth indices for a site compiled from multiple treering samples). Reconstructions of climate variables are included with some of these data sets. Each data type is stored in a separate data file; the data type is coded into the file name.

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. ABSTRACT SUPPLIED BY ORIGINATOR: 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). Mean AGBi at the study site was decoupled from ecosystem C input and equal to 71 +/- 7 g C m-2 (1999-2015), which is only a minor fraction of gross ecosystem production (GEP; i.e., AGBi / GEP ~= 9 %). Moreover, C allocation to AGBi remained stable over time (AGBi / GEP; -0.0001 yr-1; p-value=0.775), contrary to significant trends in GEP (+5.72 g C m-2 yr-2; p-value=0.02) and CUE (-0.0041 yr-1, p-value=0.007). CUE was estimated as 0.50 +/- 0.03 at the study area and 0.41 +/- 0.12 across the reviewed boreal forests. These findings highlight the importance of belowground tree C investments, together with the substantial contribution of understory, ground cover and soil to the boreal forest C balance. Our quantitative insights into the dynamics of aboveground boreal tree C allocation offer additional observational constraints for terrestrial ecosystem models that are often biased in converting C input to biomass, and can guide forest-management strategies for mitigating carbon dioxide emissions.
