Classification Comments: The association differs from ~Pinus jeffreyi - Abies lowiana Woodland (CEGL008630)$$ by typically having a more open canopy (mean 37% tree cover) and the presence of a well-developed understory of Quercus vacciniifolia and other shrubs. There are 4 association with Pinus jeffreyi and Quercus vacciniifolia designated in their names. Three of these are apparently somewhat rare and occur on serpentine habitats in the Siskiyou Mountains, while the fourth appears to be a common woodland type of the Sierra Nevada in California. Further work needs to be done to review the floristics of each of these types to further elucidate their differences.
