Tree mortality, growth and liana infestation on Barro Colorado Island

The Barro Colorado Island Tree Reproduction Dataset can be found in BCITreeGrowthSurvival.csv, a csv text file containing the data records on seed production described above. The dataset contains the following labels (columns): spcode = species code family = taxonomic family species = latin species name tag = unique id for individual trees. Corresponds to metal tags attached to individual trees in each 4ha plot or the 50-ha FDP census (data DOI: 10.5479/data.bci.20130603). year = year in which lianas scores were recorded. census = referring to the plot, either Tow (towerplots) or Ing (referring to the census by Ingwell et al. 2010 in the 50 ha plot). dbh1,2 = diameter of tree in mm at 1.3 meters height or above buttresses at time point 1 (2005 for trees from the Ingwell et al. census in the 50-ha FDP see dataset, and 2003-2004 for Tower plot trees) and time point 2 (2010 for Ingwell et al. census and 2014 for the towerplots). liana = five-point scale for liana load in the first census with zero indicating a liana free tree and scores 1 - 4 indicating trees with 1-25%, 26-50%, 51-75% and 76-100% of the crown bearing lianas. status = status of the tree at the second measurement, scored as alive (A) or dead (D).
