Derek M. Schook, Jonathan M. Friedman, Jamie D. Hoover, Steven E. Rice, Richard D. Thaxton, David J. Cooper
2022, Ecohydrology (15)
Riparian trees and their annual growth rings can be used to reconstruct drought histories related to streamflow. Because the death of individual trees reduces competition for survivors, however, tree-ring chronologies based only on surviving trees may underestimate drought impacts. This problem can be addressed by calculating productivity at the stand...
