BCI.plant

The presence of the tropical trees Alchornea costaricensis and Anacardium excelsum with diameter at breast height equal or larger than 10 cm were recorded on along with environmental factors at Barro Colorado Island in Panama (Kindt and Coe 2005). These data were originally from (Pyke et al. 2001).
