DOI: 10.1002/ecs2.3569 NOTES: This data file contains raw ring-width chronologies of individual trees that died (dying) and survived (living) an insect oubreak of Phyllocnistis populiella (outbreak period: 1997 - 2013) in Interior Alaska. Living trees have ring-width measurements up to 2015 and the tree names are preceded by TA whereas dying tree ring-width measurements end in 1997-2013 and the tree names are preceded by TM.
