By applying so-called clump management and marking the age of the bamboo shoots, a better quality of bamboo and a higher yield are obtained. This also extends the life of the clump: cutting the oldest trunks creates space for new shoots. A new trunk just grows. As a result, no deforestation takes place when bamboo is harvested. The reverse is actually true: bamboo grows better if it gets more space. The yield and quality of the plantations only increases due to the annual cut.
