It was impossible to use the results that 
were obtained from Landsat-MSS 1972 and 
set them off against 1985 because the 
image of 1972 was coverd in some places 
by clouds. 
On the basis of the results achived by 
the evaluation of landsat imagery, it 
was possible to come to a decision as a 
regard that the use of landsat imagery 
for the monitoring and survey of the 
forest decline is possible. It can be 
concluded that it was possible, for 
exampel , to identify and quantify forest 
decline for three damage levels in the 
test site St. Blasien/Schluchsee FRG (D 
0-1; D2,D3, healthy/slightly damaged, 
damaged, severely damaged stands) on the 
TM data images. Furthermore it was even 
possible to quantify the damage develop 
ment through a one year period. This has 
been confirmed with the field assessment 
that has been done by the forest services 
of this test site at St.Blasien . 
A practical method for damage assessment, 
mapping and monitoring for such a large 
forest area as the test site at Erzge 
birge, can not be done rapidly without 
the use of Landsat data . It was possible 
to distinguish between the determined 
damage levels for the actual forest 
situation on Landsat images. With the 
involvement of old landsat images in the 
evaluation one can estimate the change in 
the forest area (clear cut area and in- 
creasement of non forest zone) as well as 
the change in the forest current situa 
tion regarding, damage levels in the test 
site at the Erzgebirge region.
