BCI Plot Data
The 50-hectare permanent tree plot was established in 1980 in the tropical moist forest of Barro Colorado Island (BCI) in Gatun Lake in central Panama. Censuses have been carried out in 1981-1983, 1985, 1990, 1995, 2000, and 2005. In each census, all free-standing woody stems at least 10 mm diameter at breast height were identified, tagged, and mapped. Over 350,000 individual trees have been censused over 25 years.

Soil Maps of Barro Colorado Island 50 ha Plot - On this webpage you can find copies of soil maps showing the estimated concentrations (mg/Kg) of base cations, extractable P, and ammonium and nitrate for the BCI 50 ha Forest Dynamics Plot. Kriged estimates for the 20 x 20 m quadrats are available in this excel file. A copy of the protocol used for the sampling of the plot, collection and chemical analysis of soil samples is available here.
