"DRUNKEN FORESTS" - trees lean toward depressions in the soil if the permafrost thaws
CONIFEROUS - Gymnosperm with conical or spire-shaped needles - Conical shape prevents snow build-up - Needles minimize transpiration and desiccation - Cuticle protects from wind - Dark color absorbs heat and sunlight - Most common in North America: fir and spruce -Most common in Eurasia: Scots pine |
