Beyond proxies: towards ecophysiological indicators of drought resistance for forest management.

ABSTRACT: As drought-induced mortality increases globally in forest biomes, it becomes necessary for foresters to have access to reliable predictors of species vulnerability to drought and mortality risk under different climatic scenarios. On one hand, there exist several 'operational' indicators of drought resistance, which are based on technical literature, observations, expert knowledge and species bioclimate. However, they are not available for all species, reduce a species to a single value and have the same limitations as species distribution models. On the other hand, different traits can be measured to estimate mechanistically species' vulnerability to drought and, in particular, to hydraulic failure, a key process of tree mortality under drought. These traits typically include xylem vulnera
