Vegetation health trend
Monthly greenness (NDVI) from Sentinel-2, 2019–2025. Higher = greener canopy; the seasonal rhythm tracks the wet/dry cycle. The dashed line marks the stress threshold.
Real sub-meter Maxar imagery (~0.46 m) of this exact tree — drag to compare dry-season 2023 and wet-season 2024.
Mean crown diameter per year (VHR-measured).
Greenness change over 6 years. Annual sub-meter VHR captures also let you watch this hero tree’s crown grow.
The data behind this tree
