0076 Attiwill , P.M. The disturbance of forest ecosystems : the ecological basis for conservative management . ... mechanisms of gap - filling and subsequent growth and species composition vary widely with forest type and geography .

Preliminary results on logging and silvicultural effects on species composition , growth trends , regeneration and ... of remnant forest stand , regeneration and mortality as well as give insights of the forest dynamic processes .

Some of the factors affecting dispersion are the availability of the seed and the contribution of forest vertebrates which , for a lot of species , constitute a form of natural seeding of the seeds ( Lamprecht , 1989 ) .

In contrast , the timber harvesting operations carried out during 1989-1990 had a clear influence on the ... those plots located in roads and gaps , in which the numbers of both individuals and species were significantly lower in 1994 ...

However , efforts should be made to resemble the species mix typical for northern hardwoods , i.e. , to manage for sugar maple ... mapping approach fills an information gap that currently cannot be addressed by any other single method .

The four - step process used by Ramos and Finegan involved : 1. the delimitation and mapping of different forest types to facilitate a conservation gap analysis ( the representativity function , for natural community types ) 2. the ...
