White alder is native in our area and is an important nitrogen fixer. In other words, it converts ammonia into a form that is usable by other plant species. It is a member of the birch family, and can be distinguished from red alder because its leaves margins do not curl under. It is commonly found near streams and is the only native alder in southern California. Because of this, it is commonly used in southern California to indicate the presence of water.The roots have traditionally been used to make baskets. The inner bark was traditionally dried, ground, and mixed with water to create a dye. The wood is not valuable for lumber, but is commonly used for fuel.
