- •
We studied the mortality in unmanaged 100–150 years old Norway spruce forests.
- •
Climate extremes acted together with competition to cause sharp growth declines.
- •
Most dead trees had one to several growth declines lasting from few years to decades.
- •
Trees which died had significantly lower initial radial growth.
- •
More frequent future droughts may contribute to higher rates of mortality in subalpine forests.
