Do drought-affected trees die of thirst or hunger?

A new study has concluded that, universally, trees that have died from drought are unable to transport water to their leaves. The findings also highlight trees that have drained their carbon reserves since they are not able to carry out photosynthesis. The results of the study will permit the creation of more precise models for predicting the effects of climatic changes on vegetation.

Mathematics in the fight against forest drought

A study by CTFC and CREAF scientists has led to the development of a mathematical model which predicts drought stress in forests. The research shows that forest drought stress depends on climatic conditions as well as vegetation and soil characteristics.

Scientists consider it key to understand why droughts kill so many trees and the influence of local forest histories on tree mortality. They also warn that we know very little about the joined effects of different disturbances on each ecosystem, and highlight the necessity to plan research projects covering more time and space.
