Implication

This analysis identifies optimal phenological stages and spatial resolutions for monitoring species diversity in tropical forests, indicating effective methods for satellite-based estimations.

Key Points

The optimal phenological periods for estimating species diversity were identified at the beginning and end of the growing season, especially September.
Richness and Shannon-Wiener index estimations were most accurate at a spatial resolution of 4–5 m, fitting the average tree crown size.
Stepwise linear regression models were used to assess the influence of various heterogeneity metrics on species diversity indices.
Monitoring species diversity depends heavily on the spatial and temporal scales of remote sensing data, suggesting practical guidance for tropical forest assessments.
