Discussion

Analysis of 32 vegetation indices identifies optimal model for estimating carbon in mangrove forests, supporting conservation efforts.

The TrIVCag model achieved the highest correlation with above-ground carbon measurements, indicating its effectiveness.
Field data collected in 2023 from western Bali's mangroves shows a total carbon stock of 34,994.55 tonC/ha.
Correlation was highest for the Simple Ratio index at 0.847, underscoring the importance of vegetation indices.
This approach facilitates scalable carbon monitoring, enhancing blue carbon conservation outcomes.

Novanda et al. (2025) studied this question.
