This state's classification carries no date range for the species.
MDC field guide: "A species of conservation concern in Missouri," with restoration efforts ongoing in east-central Missouri. Not listed among huntable species on MDC's hunting/trapping species index; dedicated MDC hunting-regs URL for ruffed grouse returns 404. Page frames active grouse hunting as occurring in other states, not Missouri.
Confirmed: hunting has been closed statewide since 2010 (Missouri Conservation Commission action, citing low hunter interest/success), and MDC's remaining ruffed grouse work is a habitat-restoration and captive-release reintroduction program in east-central Missouri (most recent capture-and-move effort 2021) rather than any hunter-facing population survey — no forecast program exists.
