This happens because taproot formation is impossible, so trees developed shallow root beds.
Permafrost is soil that has a temperature below 0 °C (for about two years) and forms a solid matrix which can extend to a depth of hundreds of meters. Because of this structure the permafrost prevents trees from developing deep root systems. As a consequence, the shallow root bed of trees such as black spruce, causes them to lean or even fall.
