Grouse make up a considerable part of the vertebrate [[Biomass (ecology)|biomass]] in the Arctic and Subarctic. Their numbers may fall sharply in years of bad weather or high predator populations—significant grouse populations are a major food source for [[lynx]], [[fox]]es, [[marten]]s, and [[bird of prey|birds of prey]].{{citation needed|date=October 2020}}

The three tundra species have maintained their former numbers.  The prairie and forest species have declined greatly because of habitat loss, though popular game birds such as the [[red grouse]] and the [[ruffed grouse]] have benefited from habitat management. Most grouse species are listed by the [[IUCN]] as "least concern" or "near threatened", but the [[greater prairie chicken|greater]] and [[lesser prairie chicken]] are listed as "vulnerable" and the [[Gunnison grouse]] is listed as "endangered". Some subspecies, such as Attwater's prairie chicken and the [[Cantabrian capercaillie]], and some national and regional populations are also in danger.<ref name=Firefly/> The wild turkey precipitously declined before returning to abundance, even in developed areas.
