The western hemlock, scientifically known as Tsuga heterophylla, is a coniferous tree native to the western regions of North America. It typically grows in moist, shaded areas and can reach heights of up to 200 feet. The tree is characterized by its drooping branches and soft, flat needles that are dark green on top and lighter underneath. This species plays a vital role in its ecosystem, providing habitat and food for various wildlife, including birds and small mammals. The western hemlock is also valued for its wood, which is used in construction and furniture making due to its strength and durability.
