An Assessment of Avicennia marina Forest Structure and Aboveground Biomass in Eastern Mangrove Lagoon National Park, Abu Dhabi
Bibliographic record
Abstract
This study reports on the population structure and aboveground biomass of Avicennia marina to better understand the status of this tree species. In situ data include 20 random circular plots and measurements recorded from 2 216 individual trees. Direct measurements include tree status, stem number, diameter at breast height (DBH), and height; derived measurements include density, basal area, average crown spread, plot height, mortality rate, and aboveground biomass (AGB). The results show significant variations in density between the sampling plots, which have a total basal area of 20.58 m2 ha−1. Basal area mortality rate is very low (0.2 %), which indicates a healthy forest. The frequency distribution for tree height is positively skewed, meaning that these plots contain many small and few large trees. The distribution of DBH and average crown spread follows a reverse-J-shaped pattern, which is typical of naturally regenerating forests with a high population of seedlings and saplings. Finally, estimated ...

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.
