Greater prairie-chicken hunting has been closed statewide in Oklahoma since 1997, but ODWC runs active annual spring lek survey routes in Kay/Osage/Nowata/Craig counties (a documented decline from 32 leks in 2005 to 7 in 2024) -- a clear 'monitoring continues despite closure' case, mirroring CO/ND/CA/IL elsewhere in this registry. Publication is irregular feature-article style (most recent found: Aug 15, 2025); a fresh search this pass found nothing newer, confirming no 2026 figures have surfaced yet.
