History of the site
The demonstration site is located next to the place of the installation of the arboretum, making possible the use of the data from the weather station. The main objective is to reveal optimal planting densities of test species through the study the available space for development of each plant and the alignments between them. MAIN SYLVICULTURAL OPTION DEMONSTRATED: New mixed plantation of two codes of Eucalyptus nitens in an area affected by Micosphaerella sp. using systematic designs in concentric circles with different grid of plant positions, varying the spacing from low to high density and the degree of composition of both species. The demonstration sites are plantations based on Nelder Wheels (Nelder, 1962) designed to evaluate the influence of the density on the mortality, the size, the pathogenic damages and the biomass allocation of each plant. The data analysis will be performed using logistic regression and spatial analysis.
