Somewhere it might be useful to cite DeSoto et al. 2020, who conducted a global meta-analysis and found that in angiosperms, drought mortality risk was related to low resistance, but in gymnosperms it was related to low recovery.

DeSoto et al. 2020. Low growth resilience to drought is related to future mortality risk in trees. Nature Communications 11:545.

Sapes et al. (2019) found that plant volumetric water content was a better predictor of drought-induced mortality than percent loss of conductivity or measures of non-structural carbohydrates. Volumetric water content is also easier to measure, and it can be estimated over large areas using remote sensing.

Sapes, G, B Roskilly, S. Dobrowski, M. Maneta, W. R. L. Anderegg, J. Martinez-Vilalta, and A. Sala. 2019. Plant water content integrates hydraulics and carbon depletion to predict drought-induced seedling mortality. Tree Physiology 39:1300-1312.

Sapes citation added. DeSoto is really cool, but not so relevant here (not a species trait).

side note: in your region, there has been much less drought, fewer extended droughts, or less severe droughts during the period of field studies than vs the time of some of the oldest trees. Tree rings can help overcome this limitation/many field studies are biased to one of the wettest eras of the last 500 years:

This is a good point, but I don't see where it fits nicely.
