The majority of Brewer spruce overstory associates are listed in the Distribution and Occurrence frame. Strobilus buds appear in early summer, accompanied by the shedding of pollen, at which time the conelets are receptive. The male strobili develop from axils of needles of the previous year's shoots. After pollenation, the strobili dry and fall from the tree and the conelets turn down and mature over the summer, into September and October. In a series of fires in 1987 that burned throughout the range of Brewer spruce, low-intensity surface fires killed Brewer spruce in mixed stands.
Brewer spruce recovery from fire is generally slow.
