Discussion
Fruits of Gaultheria shallon are a food source for animals, and the evergreen leaves provide additional food throughout the winter. This species has been used as a vegetative cover in disturbed areas because it spreads aggressively. The fresh and dried or smoked fruits were an important food of native peoples throughout its range. The evergreen leaves are used commercially in floral arrangements.
