Estimating the Threshold of Detection on Tree Crown Defoliation Using Vegetation Indices from UAS Multispectral Imagery

Periodical outbreaks of <i>Thaumetopoea pityocampa</i> feeding on pine needles may pose a threat to Mediterranean coniferous forests by causing severe tree defoliation, growth reduction, and eventually mortality. To cost&#8722;effectively monitor the temporal and spatial damages in pine&#8722;oak mi...
