"The fruit, consisting of small purplish berries that ripen in the autumn, is consumed by native wildlife, especially migrating birds." 
"Wax from the pulp of the fruit was used to make aromatic candles. The wax was also used in making soups. A gray-brown and a maroon-purple dye was obtained from the fresh or dried berries. This species was easily grown and valued especially on the Pacific Coast for its berries and evergreen leaves." 
"Myrica californica is used in tree strips for windbreaks. They are planted and managed to protect livestock, enhance production, and control soil erosion. Windbreaks can help communities with harsh winter conditions better handle the impact of winter storms and reduce home heating costs during the winter months. They also provide shade and wind protection during the summer, which aids in the reduction of cooling bills."
