Data for modeling the height and diameter of Pinus merkusii and P. michoacana in Zambia

Data on tree height and diameter of non-native Pinus merkusii (Jung. & de Vriese) and Pinus michoacana (Martinez) collected from Zambia's non-native forest plantations is presented here. A total of 1542 and 1883 pairs of height and diameter datasets for developing and testing the models are presented, respectively. During a five-year interval forest inventories, data collected supported the development of allometric relationships between height and diameter for the country's two species. Datasets are intended to be reused for various purposes to enhance the understanding of the tree height and diameter relationships of new and existing planted non-native species in Zambia. For detailed examples of the application of this data, see the article, “Stand characteristics and climate modulate height to diameter relationship in Pinus merkusii and P. michoacana in Zambia” Ng'andwe et al., 2021.
