BCI 50-ha Plot Taxonomy

The 50-ha plot at Barro Colorado Island was initially demarcated and fully censused in 1982, and has been fully censused 7 times since, every 5 years from 1985 through 2015 (Hubbell and Foster 1983, Hubbell et al. 1990, Condit et al. 2012, Condit et al. 2017). The taxonomic component required repeated collecting and sorting so that every individual could be matched to a previously described species from Croat (1978). Over 300 taxa were separated and all but 8 of those identified to species. After the 8th census in 2015, a total of 328 tree taxa have been documented in the plot, though the number alive in any one census has been less. Taxonomy of tropical plants is still in a state of flux because many of the groups have not been studied in detail for decades, and new treatments, especially those using DNA phylogenies, invariably lead to revision and reidentification. To maintain the 50-ha plot up-to-date with recent taxonomy, we have had to make numerous changes to the original list of 300 species. In Condit et al. (1996) we listed every species and added an Appendix documenting revisions done up until that date. In Condit et al. (2004), another species list was provided, but with no list of revisions. Many other papers mention some species, but none since list all species.

Here we provide a complete list with updates since 2004, and with it a list of all obsolete names ever used with a match to the current valid name. We acknowledge, of course, that taxonomy continues and further revisions will be inevitable. The data were frozen as of 1 May 2019, so users will always be able to consult the 2019 version. It updates a 2017 archive with the same format (https://doi.org/10.25570/stri/10088/32990). The same taxonomic tables also appear online in a searchable and sortable format designed to let users explore the data easily (http://conditdatacenter.org/taxonomy/BCI/BCIPlotFullTaxonomy.php). That web site, however, is maintained by one of the PIs and is not guaranteed to be permanent, that is, after he retires from the project it will disappear.
