Mountain hemlock is a coniferous tree native to the mountainous regions of the western United States and Canada. It typically grows in cool, moist environments and can reach heights of 50 to 100 feet. The tree is characterized by its slender trunk, drooping branches, and short, needle-like leaves that are dark green on top and silvery underneath. This species thrives in well-drained soils and is often found at higher elevations, where it plays a crucial role in the ecosystem. Mountain hemlock is also valued for its wood, which is used in construction and furniture making, and it provides habitat for various wildlife species.
