This mighty tree is known to us as the Douglas Fir, however, it’s scientific name is Pseudotsuga menziesii.


Douglas firs are a major component of succession in the forest. Since they have almost no seedlings and cannot grow in the shade. Thus, when a tree dies the canopy opens up and sunlight becomes available as a source of energy for new growth. Now, the seedlings from other species that can thrive in the shade can get a head start. Meanwhile, the Douglas Firs are struggling. This results in trees such as the western hemlock dominating the canopy of a lowland rainforest.
