Bridge: plots of old-growth forest to gather information on tree diversity and to test ecological theories in French Guiana since 2007.

The project Bridging Information on Tree Diversity in French Guiana, and a Test of Ecological Theories (BRIDGE) brings together researchers from nine different European research groups in tropical ecology, and seeks to improve our knowledge on the various dimensions of tree biological diversity in French Guiana. The project includes ten one-hectare old-growth forest tree plots across a range of geology and rainfall in French Guiana. The amount of niche conservatism across an ecologically relevant set of functional, reproductive, and defense traits have been measured in the field.
