Texas's population is Attwater's prairie-chicken (critically endangered subspecies), closed to hunting statewide but under active monitoring. At The Nature Conservancy's Refugio-Goliad Prairie Project reintroduction site near Goliad, the total population count rose from 82 birds (2024) to 102 (2025) to 138 (2026), per TNC's own project page (fetched directly 2026-08-19) -- a third consecutive annual increase at that specific site, distinct from the original Attwater NWR refuge population (most recently counted in 2021 at 89 booming males / ~178-bird estimate, not independently updated this pass). About 17-20% of 2025's males were wild-produced, per the same source.
