Tree census data for the 25-ha, 10-ha and tower plots on Barro Colorado Island, Panama

This data publication contains tree census data from 2004–2005 and 2014–2015 for six forest plots on Barro Colorado Island, Panama. These include the 25-ha and 10-ha plots, as well as four 6-ha tower plots: AVA, Drayton, Pearson, and Zetek. Censuses recorded all trees with a diameter at breast height (DBH) of 20 cm or larger. Census methods followed standard methods, as described in detail in detail in Condit (1998). The dataset was organized and quality-checked by Stuart Joseph Wright. Files included: Vertices_HM.csv provides the geographic coordinates of the four corners for each plot, outlining their boundaries. Coordinates are provided in UTM (WGS84; EPSG:4326). For each plot, two data files are included (12 files total): a file containing data from both census periods for the largest stem of each tree (e.g. 10ha_WorkingDraft_20150304.txt) a file containing data for additional stems, when present, from the 2004-2005 census. (e.g. 10ha_MULT.csv) Data dictionaries accompanying these files provide definitions for all columns, including explanations of any categorical abbreviations. BigPlotDataDictionary_main.txt BigPlotDataDictionary_mult.txt TreeCodeDefinitions.txt Meakem et al. (2024) describe these plots and present analyses of these data.
