Every year or two, the trees in the plantation must be recalculated. The aim is to find out whether the number of trees has decreased due to disease or due to nature like landslides or by lightning.
This year, the number of Asian teak, Mahogany and Acacia trees was recalculated, there was a reduction in the number but not significant, only about 2 % of the trees died since planting in 2005.
While recalculating, re-measuring can also be done to determine the growth of the trees. Teak trees, or other hard trees, usually do not grow much after ten years. For Mahogany and Acacia trees, the growth is slow, because the canopy covering the soil, the sunlight has very little to reach the root. The absorption of nutrients for the roots is slightly hampered.
Regular maintenance and cleaning of the soil from weeds, at least can help the tree to get enough sunlight & nutrition. Asian teak, Mahogany and Acacia trees look healthy and free from diseases.
