UPM Forestal Oriental Annual Report 2022

FORESTRY

GROWTH MONITORING

In order to achieve our goals of sustainable timber supply, a stable forest base is needed to ensure a suitable site-species relationship. For this purpose, UPM Forestal Oriental has incorporated state-of-the-art machinery to help simplify operations and increase the efficiency of the forestry process. The main base species used are Eucalyptus grandis, E. dunnii and their hybrids. Other species such as E. globulus, E. maidenii and E. benthamii are used for breeding with base species to enhance pulp production and the plant’s ability to adapt to different environments.

Growth is monitored though permanent plots that are measured annually from their first year of planting until the end of the land’s cycle. We take stock with temporary plots in every field a few months before harvesting. The indicators obtained are: Trees/ha. Average diameter
