Abies lasiocarpa, commonly known as the subalpine fir, is a coniferous tree native to the mountainous regions of western North America. It typically grows at elevations between 1,500 and 3,600 meters, thriving in cold, moist environments. The tree can reach heights of 15 to 25 meters and has a narrow, conical shape with soft, flat needles that are dark green on top and silvery underneath. The bark of Abies lasiocarpa is smooth and grayish-brown when young, becoming more rugged and fissured with age. This species produces cylindrical cones that are 5 to 10 centimeters long, which mature in the fall. It plays a vital role in its ecosystem, providing habitat and food for various wildlife species.
