An assessment of growth responses of healthy versus declined oaks

Dendrochronology and dendroclimatology techniques were used to examine radial growth differences between paired “healthy” and “declined” oak trees in each of four locations across the Southeast.

In each case, initiation of growth decline was associated with a major drought or series of droughts.
