The shade-intolerant mountain pines follow diverging growth trajectories that are imposed by extrinsic environmental influences. Variability in lifespan was further contingent on aspect, slope steepness and elevation. Early growth was not correlated with temperature or precipitation over the growing period. Slowly growing mountain pines may reach a large diameter and a long lifespan, but risk to die young at a small size. rapidly growing mountain pines face a trade-off between reaching a large diameter at the cost of early tree death. mean tree-ring width over the first 50 years) correlated positively with diameter at the time of tree death, a negative correlation resulted with lifespan, i.e. For 200 dead standing mountain pines ( Pinus montana) located along gradients of aspect, slope steepness and elevation in the Swiss National Park, radial annual growth rates and lifespan were reconstructed. The main objective of this study was to investigate the relationships between radial growth, tree size and lifespan of shade-intolerant mountain pines. A within-species trade-off between growth rates and lifespan has been observed across different taxa of trees, however, there is some uncertainty whether this trade-off also applies to shade-intolerant tree species.
