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.法属圭亚那树木多样性信息衔接与生态学理论检验项目（BRIDGE）汇聚了来自欧洲9个不同热带生态学研究团队的科研人员，旨在加深我们对法属圭亚那树木生物多样性各维度的认知。该项目在法属圭亚那不同地质与降雨梯度区域设置了10块1公顷的原始森林树木样地，并已在野外实地测量了一系列与生态学相关的功能、繁殖及防御性状的生态位保守性水平。
