The reasons for the decline are poorly understood. Habitat loss and hunting have been hypothesized as possible reasons for the decline. Few studies have centered on this bird despite of its expansive range.
More information is needed to provide better understanding of population status.
Spruce grouse are listed as a species of special concern. Suitable low elevation habitat is rare in the state. Most populations found in high elevation spruce and fir forests in the White Mountains. White Mountain habitat is also thought to be declining due to acid deposition and heavy recreational use. More information is needed about population size, breeding.
