The study specifically re-evaluated carbon stocks between 20032004 and 2018 at the Aleza Lake Research Forest to understand how carbon storage is impacted by tree species and size. The authors found that while younger forest stands generally accumulated carbon, older stands with larger trees showed a decline in aboveground live-tree carbon, largely due to increased mortality of these large trees. This highlights a critical concern regarding the role of mature forests in carbon sequestration amidst accelerating climate change and increasing tree mortality rates. -
