Abstract EN
This study tested the effects of inserting climatic variables in Eucalyptus grandis as covariables of a dominant height model, which for site index classification is usually related to age alone.
Dominant height values ranging from 1 to 12 years of age located in the Southeast region of Brazil were used, as well as data from 19 automatic meteorological stations from the area.
The Chapman-Richards model was chosen to represent dominant height as a function of age.
To include the environmental variables a modifier was included in the asymptote of the model.
The asymptote was chosen since this parameter is responsible for the maximum value which the dominant height can reach.
Of the four environmental variables most responsible for database variation, the two with the highest correlation to the mean annual increment in dominant height (mean monthly precipitation and temperature) were selected to compose the asymptote modifier.
Model validation showed a gain in precision of 33% (reduction of the standard error of estimate) when climatic variables were inserted in the model.
Possible applications of the method include the estimation of site capacity in regions lacking any planting history, as well as updating forest inventory data based on past climate regimes.
