Abstract
Spectral measurements of beech branches and branch components were performed in the laboratory from 0.5-2.5µm. The measurements focused on primary effects influencing the spectral signature of healthy and damaged beech trees. Saturation of the reflected radiance is reached with a stack of 5-7 layers for branches and leaves. Differences between branch and leaf spectra can be attributed to the amount of bark, nuts, etc. Their contribution to the spectral reflectance is also responsible for the possibility to discriminate between healthy and damaged beech branches in the NIR and SWIR. Leaves of different degree of damage can be distinguished in the VIS. The spectral variations observes in this region are similar to those observed for healthy and damaged branches.
