Forest health monitoring is crucial for sustainable management, especially with the challenges posed by climate warming. Remote sensing data provide vegetation indices, such as Normalized Difference Vegetation Index (NDVI) and Enhanced (EVI), that are widely used in assessing forest health. However, studies considering validation of these field assessments tree vigor still scarce. To address this issue, we explored relationships declining (D) non-declining (N) silver fir (Abies alba Mill.) stands from Spanish Pyrenees between changes canopy (a proxy vigor), indices (NDVI, EVI) variables. We compared trends NDVI EVI period 1984–2023 D N showing high low crown defoliation levels, respectively. The values allowed separation according to their earlier more clearly than values, which did not show clear patterns throughout time series. Significant negative correlations were found stand (r = −0.57) or mean radial growth 0.81). Late-spring drought reduced EVI. series reflected similar spatial terms growth, offering complementary information, along strengths remote respect its temporal coverage, early detection dieback. This study also contributes a better understanding useful monitoring.
