Productivity-Based Land Suitability and Management Sensitivity Analysis: The Eucalyptus <i>E. urophylla</i> × <i>E. grandis</i> Case
Published 2022-02-01“…In this study, we perform a systematic analysis of factors influencing eucalyptus growth through plot records from the National Forest Inventories and satellite images. We find primary restricting factors for eucalyptus growth via machine learning algorithms with random forests and accumulated local effects plots, as conventional forest growth models are inadequate to calculate the causal effect with the large number of environmental and socioeconomic factors. …”
