Competition‐induced tree mortality across Europe is driven by shade tolerance, proportion of conspecifics and drought
International audience 1. Forest stand densities are increasing in the boreal and temperate biomes, suggesting that tree-tree competition is intensifying. Anticipating the consequences of this intensified competition is difficult because competition-induced mortality may depend not only on the occur...

Forest stand densities are increasing in the boreal and temperate biomes, suggesting that tree-tree competition is intensifying.

Competition, measured as the basal area of larger trees, was a stronger driver of background mortality (BM) than tree size and climate. A higher proportion of conspecifics increased the competition effect on mortality, showing that conspecific individuals had a higher competitive effect compared to heterospecific individuals. The competition effect on mortality also increased as a function of the ST of neighbouring trees, suggesting an increased shading effect. A higher ST of a focal tree decreased the competition effect on mortality. Drought anomalies increased the competition effect, resulting in a higher mortality probability for the most suppressed trees.
