Data were obtained from the observation of ten individuals from ten species growing in a semiarid area of Caatinga vegetation under natural conditions in the Northeast of Brazil in Paraiba State, located at the Fazenda Pocinho (7º29'46" S, 35º58'12" W) in the municipality of Barra de Santana, Brazil. The woody crowns were drawn (skeletonized) in the 2-D format as rooted trees resulting in networks with nodes and connectors following the methodology described by Prado et al. (2020, https://doi.org/10.1016/j.jtbi.2020.110318). Skeletonized crowns capture the data of decomposition, topology, and properties.
