Not all trees can make a forest: tree species composition and competition control forest encroachment in a tropical savanna

This dataset consists of three files: individual tree data, plot-level data, and soils data (also collected at the plot level). Tree_data_EEcAssis.xlsx: Thirty plots were established in 2006 along a gradient from open savanna to closed forest. Each plot comprised 20 x 50 m, within which all trees > 5 cm DBH were sampled. For each tree, DBH, height, and species identity were recorded. Individual trees were tagged and resurveyed in 2011 and 2016, along with any new recruits into the 5 cm size class. Soil_EEcAssis_All data.xlsx: Within each plot, soil structure and chemistry were sampled at a depth of 0-20 cm and 60-80 cm. Samples were commingled to produce one sample per plot. Plot_data_EEcAssis.xlsx: Some variables are summarized to the plot level in this spreadsheet, to facilitate analysis. For details on data collection, see Assis, et al.
