Current information on NW Amazonian plant diversity shows that tree alpha diversity is high in relation to gamma diversity. This corresponds to low levels of tree beta diversity. It also indicates that we may expect spatial mixing of tree taxa in the region. This latter hypothesis is tested by comparing taxon composition of lowland Amazonian forests in Colombia, Peru, and Ecuador at various spatial scales. Also, soil analytical data are compared to evaluate mesoscale edaphic diversity. The data shown are initial results of an EC project to assess non-timber forest resources in NW Amazonia**.** http://www.frw.uva.nl/icg/NTFP/flyereng.html
