UPM Forestal Oriental - Social and Enviromental Report 2014

3. NURSERY The nurseries aim to produce Eucalyptus seedlings, either by seed or through vegetative propagation (rooted cuttings). We also develop new production techniques, reducing costs and improving quality without having a negative effect on the environment.

We have an infrastructure capable of producing 35 million seedlings per year, between the San Francisco Nursery, on the outskirts of Paysandú, and the Santana Nursery in Guichón.

4. PLANNING The Planning Department evaluates the land for tree planting, develops and coordinates the company’s timber supply plans and plans the land use to optimise the use of natural resources, minimising negative impacts and maximising the positive impacts caused by our operations.

5. PLANTING In order to achieve the proposed objectives, we need to have a stable forest ground to ensure the correct site-species relationship. To achieve this, we rely on the species Eucalyptus grandis and its hybrids, which are planted in warmer and topographically higher locations. In the low-lying areas we plant species or hybrids that are more resistant to the cold. New working techniques allow us to use soil with forestry aptitude previously regarded as marginal due to its rock

6. MONITORING GROWTH Growth and dynamics are monitored in forests through permanent plots (PP) that are measured annually from their first year of age. Forest plantations are also evaluated twice throughout the shift: after 5 years and prior to harvesting. The basic indicators obtained are: site index (dominant height of the trunk after 8 years), trees/ha, average diameter, average height, dominant height, basal area, volume/ha, average annual increase, current annual increase and average tree volume. The results obtained are used both to keep the timber stocks updated on the forest plantations, and to evaluate the potential of different species and genotypes, analyse management measures, etc.
