Furthermore, stability must be viewed as a function
of time and space. The persistence of species as a stability
feature is closely connected with the spatial
dimension of ecosystem (Grimm et al., 1992). The
impact of different silvicultural measures and management
systems on ecosystem stability suggests a certain
spatial dimension (the mosaic cycle concept; Remmert,
1991)) and that the temporal horizon should exceed
more than one tree generation, thereby including the
regeneration stage.
