Red alder

Red alder (Alnus rubra) is a fast-growing deciduous tree native to the Pacific Northwest of North America. It typically reaches heights of 50 to 80 feet and has smooth, reddish-brown bark. The tree thrives in moist, forested areas and is important ecologically because it enriches the soil through a process called nitrogen fixation, which improves soil fertility. Its leaves are broad and oval-shaped, turning bright yellow in fall. Red alder is valued for its lightweight, durable wood used in furniture, cabinetry, and plywood, and it also provides habitat and food for various wildlife species.
