Tree species richness was lower in clearcut stands than
in the unmanaged ones, but no significant effects of
clearcutting were found for the rest of the biodiversity
indicators (Table 1). We did not find any significant effect
for shelterwood treatments due to the small number of
plots.
The maximum basal area removal occurred with clearcutting
(about 64%), nearly double that of selection cuttings, and
more than five times larger than the average of 12% caused by
natural mortality and disturbances in unmanaged stands
(Table 1).
