Douglas-fir

CAN BE FOUND IN:

Douglas-fir

Pseudotsuga menziesii

APPEARANCE 

Douglas-fir is not a true fir, so the official name is written with a hyphen to differentiate it from true fir trees (such as Grand Fir). The Douglas-fir grows to 20-100 metres tall, but the tallest trees are only found on the B.C. coast. Its cones have three forked bracts on each scale. The bark is reddish brown, deeply grooved and can grow over 30 centimetres thick. This thick bark is used as a defense against fire and insects. Bears like to rip it off to eat the sap underneath. 

RANGE & HABITAT 

The Douglas-fir is found in western Canada, the US and northern Mexico. It can be found in a range of regions from rocky, dry mountainous areas to temperate rainforests.

RECIPROCAL RELATIONSHIPS 

Douglas-fir is a quick growing tree in its early years. The Douglas-fir is also known for its thick bark used as a defense against fire and insects. Douglas-fir is often one of the first tree species to grow after a fire, and they often survive through very hot fires because of their thick bark.

This is an important being for many animals. The seeds can be eaten by birds and mammals. Tussock moth caterpillars feed on the needles of the Douglas-fir; when they hatch, they first feed on new foliage and as they mature, they begin to eat all leaves. Bears like to rip off the bark and eat the sap underneath.

For the Coast Salish people, the wood of Douglas-fir can be used to build longhouses, canoes, and totems. For the Nuu-chah-nulth people, these trees are used as a heat source and for ceremonies.
