Tree species abundance through time in tropical forest census plots, Panama

All trees at least 1 cm diameter at breast height were censused in three sites in Panama. The Barro Colorado plot is 50 hectares in area and was fully censused on eight occasions between 1982 and 2015. The Sherman plot is 5.96 hectares and was fully censuses four times between 1996 and 2009. The Cocoli plot is 4 hectares and was censused three times between 1994 and 1999. The three accompanying tables give the population size of living individuals of all species in every census at the three sites. 

Methods
Every individual was mapped, tagged, and identified if the diameter at 1.3 m above the ground was at least 1 cm. Individuals with multiple stems from one root base were counted as single trees. Every tree was identified with reference to herbarium specimens and published flora (especially T. Croat's Flora of Barro Colorado Island [Stanford, 1978]). Some trees were assigned into distinct morphotypes but could not be fully identified, and a small number of individuals were never identified. Methods are described in detail in Condit, R.
