929. Congo, Conkouati National Park, 2007 In the Cotovindou logging concession Congolese workers for the Chinese timber company Sicofor move away as a 20 meter bilinga tree they have just sawed comes crashing down. It will be loaded the same day on a truck bound for Point Noire. From there it will be embarked for China. It will probably end up as luxury flooring in Europe or the States. The bilinga (Nauclea diderrichii) tree has been included in the red list of IUCN (International Union for Conservation of Nature and Natural Resources) in 2004.
