How is Douglas fir adaptations to the temperate rainforest?

Douglas fir (Pseudotsuga menziesii) is well adapted to the temperate rainforest through its thick, fire-resistant bark, which protects it from wildfires. Its needle-like leaves minimize water loss while still allowing photosynthesis, and the tree's deep root system helps it access groundwater during dry periods. Additionally, Douglas fir can thrive in the shade of other trees, allowing it to grow in the dense, competitive understory of the rainforest. These adaptations enable it to survive and flourish in the moist, nutrient-rich environment of temperate rainforests.
