The distributional range of Quercus garryana, its naming, botanical features, and geographical variants are briefly described. A short discussion of the historical utilization of Garry oak as a timber species, its habitats and ecology, including a listing of common pests and diseases is presented. The prominence of cultivated and wild stands of Garry oak, as well as the significant historical role of Garry oak acorns as an aboriginal food plant and trade item, and the relationship between historical meadow management, biodiversity, and conservation in Garry oak ecosystems is examined.
