Comparing the three intensities of thinning (by
N, G, and V) one may say that the approaches to
thinning used by various participants range from
thinning from below (participants no. 2, 9) to mixed
thinning (participants no. 4, 8, 10) or even thinning
from above (no. 1, 5, 7, 12, 15). Such result is very
surprising as all participants were asked since the beginning
to use a combination of selection of final
crop trees and thinning from above that is considered
as the best approach that should be used in case of
European beech silviculture in Romania as in other
parts of our continent.
4. Conclusions
The above field exercise seems to be a good
example of the practical use of demonstration plots
when training professional foresters. It shows that the
interest and understanding of different people can be
very variable and, combined with the lack of experience
in a brand new f ield it can lead to very variable
results such as extremely high volume of thinning/
ha. It seems to be a quite long way up to the large scale
application of single-tree silviculture in European

is performed since at least 20 years ago in the central
part of Europe.
In addition, such exercise is an excellent opportunity
for professional foresters to exchange views,
impressions, misunderstandings and think together
about the future of Silviculture (Photo 3). Such exercises
should be repeated because they stimulate reflection
and openness.
