| Abstract |
During 1993/94 the rhineland-palatinatian Bienwald, like other warmer regions of Germany, has
been seriously affected by a gypsy moth (Lymantria dispar L.) infestation. Due to this infestation
large parts of the Bienwald were defoliated completely. Moreover, severe log-term damages have
been observed in spring 1995 on oak stands (Quercus robur L.) of all age groups. These long-term
damages are still under examination within a project of the Land Government of
Rhineland-Palatinate (Block, 1995, Delb, 1996).
Defoliation assessment commonly involves ground surveys and photographic interpretation, which
can be subjective and labour intensive. Within this study we used Landsat Thematic Mapper data
for the assessment of the damaged areas. Furthermore the connection between damage done by
caterpillars, pest control and the resulting long-term damage from the insect impact are analysed
by means of GIS. First results of an modelling approach will also be presented.
