POPULATION STATUS AND HARVESTS:MID-CONTINENT AND ROCKYMOUNTAIN POPULATIONSofSANDHILL CRANES2002
Bibliographic record
Abstract
The abundance of the Mid-Continent Population of Sandhill Cranes has been relatively stable since the early 1980s, compared to the increases that were recorded in the 1970s. The Central Platte River Valley, Nebraska spring index for 2004, uncorrected for visibility bias, was 356,850. The photo-corrected 3-year average for 2001-2003 was 370,300, which is within the established population objective range of 343,000-465,000 cranes. All Central Flyway states, except Nebraska, allowed crane hunting in portions of their respective states during 2003- 04. About 7,700 hunters participated in these seasons, which was similar to the number that participated in the previous year’s seasons. Hunters harvested 18,527 in the Central Flyway during the 2003-04 seasons, which was 42% higher than the harvest for the previous year. The retrieved harvest in the Pacific Flyway, Canada, and Mexico combined was estimated at 13,109 during 2003-04. The preliminary estimate for the North American sport harvest, including crippling losses, was 35,706, which is 28% higher than the previous year’s estimate of 27,839 and the second highest harvest recorded. The long-term (1982-2000) trends for the Mid- Continent Population indicate that harvests have been increasing at a higher rate than population growth. The fall 2003 pre-migration survey estimate for the Rocky Mountain Population was 19,523, which was similar to the previous year’s estimate of 18,803. The 3-year average for 2001-2003 is 18,295, which is within established population objectives of 17,000 - 21,000. Hunting seasons during 2003-04 in portions of Arizona, Idaho, Montana, New Mexico, Utah, and Wyoming, resulted in a harvest of 528 cranes, a 17% decrease from the harvest of 639 the year before.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
