Alnus rubra (red alder) is a deciduous broadleaf tree in the Betulaceae (Birch) family native to western North America. Red Alder is the largest species of alder in North America and one of the largest in the world, reaching heights of 20-30 meters. The official tallest red alder (1979) stands 32 meters tall in Clatsop County, Oregon (USA). The name derives from the bright rusty red color that develops in bruised or scraped bark. The bark is mottled, ashy-gray and smooth, often draped with moss. Large trees are often unbranched for a considerable distance from the ground. Description from Calscape
