- Alpine Zone
The portion of land that lies above treeline.
Extreme climate makes survival impossible for tall trees. If trees are present they grow no more than a few feet high or tend to sprawl across the ground. This is "krummholz".
Alpine plants usually have adaptations for minimizing the effects of wind, cold temperatures, short growing seasons, dry conditions and extreme ultraviolet radiation.
The alpine zone is nice to visit but there's no shelter there for camping - just krummholz.
