5.3. FVI vs. stress and mortality observations
The comparison between the FVI and stress and mortality observed
in Google Earth revealed that as p-value associated with FVI decreased,
the proportion of stressed plots increased, confirming that positive FVI
areas with very low p-values (high statistical significance) are associatedwith
greater amounts of stress andmortality (Fig. 5). Below a p-value
of 0.05 (dashed line) the proportion of stressed plots rapidly increased
in association with these lower and more significant p-values (Fig. 5).
Stressed plots were also present at higher p-values, although at lower
proportions, possibly highlighting the limitations in directly linking an
800-m integrated pixel with visual observations of mortality in Google
Earth.
