[ACG43-13] Spatio-temporal variation in vulnerability and resilience of tree radial growth to climate changes in Eastern Siberia
Keywords:International Tree-ring Data Bank, Tree radial growth, Eastern Sibeira, Climate change, Vulnerability
I evaluate the response of tree radial growth to climate changes over past decades in ITRDB (International Tree-ring Data Bank) sites over Eastern Siberia. Especially, I focus on the extreme events that show remarkable decline in tree growth, their frequency and the recovery process of tree growth from the decline events, i.e., resilience. The frequency of the extreme events varied from site to site, with more frequent events observed in the Arctic sites. In terms of the magnitude of the extreme events, they also tended to be more severe in the Arctic sites. In this presentation, I would also like to discuss the temporal change for the extreme events, which is expected to vary from region to region.
