Desiccation of tree foliage is a key factor in the spread of fires. However, during droughts, changes in the water content of forest canopies remain poorly understood. Scientists from INRAE and the CNRS have developed the first model to predict canopy water content during drought and heat waves. Their results, published in the journal New Phytologist, could enable the development of fire danger forecasting models that include the role of vegetation in their calculations.
