They found that rates of tree mortality at least doubled in the drought - affected areas, to 4 - 7 %, from a long - term trend of 1.6 %. (climatechangenews.com)
Overall, increased tree mortality from increased forest disturbance may cause a reduction in forest carbon storage. (montanaclimate.org)
We found that competition was strongly correlated with tree mortality rates over the last five decades (Fig. 3 A and D). (pnas.org)
