| Note : At the European scale, spatial and temporal
variation of forest condition can only be provided by means of systematic
large scale monitoring (level 1). At this level, crown condition
has been assesed annually on a transnational grid (16x16km). It
is considered as one of the most obvious indicators but it does
not permit conclusion on direct cause-effect relation ships. |
