The article discusses a research strategy for studying the growth and yield of pine and eucalypt plantations in South Africa's Komatiland Forests. The researchers aim to create models to predict how these trees will grow over time, helping with forest management planning. They collect data from various sources like spacing trials and sample plots, and use different mathematical functions to model tree growth and response to thinning. The goal is to develop accurate models that can be used in simulation systems for planning forest management activities like thinning and pruning. Ultimately, the main purpose of these models is to improve planning systems for forestry companies.
