The 50-hectare permanent treeplot was established in 1980 inthe tropical moist forest of BarroColorado Island (BCI) in GatunLake in central Panama.Censuses have been carried outin 1981-1983. 1985. 1990. 1995.2000. and 2005. In each census.all free-standing woody stems atleast 10 mm diameter at breastheight were identified. tagged.and mapped. Over 350.000individual trees have been censused over 25 years.Since 1994. over 50 one-hectare plots and smaller have been establishedin the Panama Canal watershed and elsewhere where trees over 10 cmdbh were censused.
