Question

How has the douglas-fir adapted to enable its survival in the taiga biomes?

Answer 1

The Coast Douglas Fir is a perennial, woody plant which means it has longevity and continues growing for many years. One of these characteristics is that they have developed a bark that is thicker then many other species of trees. The bark is also almost cork-like in the way it is composed. The trees have also developed adventitious roots, which means that they grow directly out of the trunk.

Answer 2

waxy needles

Taiga is the biome with needle leaf trees. It is a cold biome. Douglas-fir have long, thin and waxy needle shaped leaves. Wax prevents the loss of water through transpiration and also prevents freezing and leaves being drying out.
