This state's classification carries no date range for the species.
Present in western Oklahoma shortgrass/mixed-grass prairie including the panhandle.Classified as a game bird and species of greatest conservation need, but hunting closed statewide since 1997. Additionally carries federal ESA-threatened status (northern DPS, covering OK panhandle range), reinforcing the closure.
Lesser prairie-chicken hunting has been closed statewide in Oklahoma since 1997 (species also carries federal ESA-threatened status), but ODWC contracts out an active annual spring lek survey (2022: 11 leks in Cimarron/Texas/western Beaver counties; 2023: 23 leks in eastern Beaver/western Harper counties; 2024: zero leks in eastern Harper/Woods counties; 2025: 19 leks in Ellis County) -- same 'monitoring continues despite closure' pattern as greater prairie-chicken above. A fresh search this pass found results only through the 2025 survey; no 2026 figures located. Also feeds WAFWA's separate range-wide aerial survey (multi-state: OK/KS/TX/CO/NM), already tracked under Kansas in this registry.
