Extended Data Fig. 8: Relationship between the extent of stand-replaced forests and changes in net CO2 fluxes.
From: Global covariation of forest age transitions with the net carbon balance
Relationship between the fraction of forests replaced by young stands (that is, stand-replacement extent) and changes in net CO2 fluxes between circa 2020 (average of 2019–2021) and 2010 (average of 2009–2011) for young (a), maturing (b), mature (c) and old (d) stand-replaced forests. The dark solid line represents the linear regression on the ensemble estimates, while the dashed grey lines indicate the regressions for the nine individual atmospheric inversion models. To smooth the spatial distribution of net CO2 fluxes, we applied a Gaussian filter (length = 500 km, equivalent to approximately four one-degree pixels). This smoothing technique reduces noise in the data and helps minimise the influence of local transport errors.
