There are three cases for the preservation of bamboo forests and adjacent forests;
bamboo forest
maintenance ratio
(C/Bx100)
Case 1: In case 1 the bamboos have invaded the adjacent forests. In that case all the bamboos are cut down. The
main reason for that is because most of the trees died or nearly died because no sunlight infiltrates any longer
the forest once bamboos have reached their full grown height.
Case 2: The zones with only bamboo are preserved the following way. First of all, the older bamboos are cut
away. Afterwards thinning of the bamboo forest occurs, until a well balanced density has been reached.
Depended on the place, 2 or 3, up to 10 and more bamboos are left on 3.3 m 2 (1 tsubo corresponds to 3.3 m 2 , a
Japanese area unit).
Case 3: The third way of preservation is keeping bamboos and normal trees together. The density of trees and
bamboos vary from place to place. The infiltration of sunlight is one of the most important elements to decide
the density of thinning the forest.
Due to the fact that all participants are non-professionals, these preservation and thinning methods cannot
always be seen as the most appropriate ones (figure 7).
