Differences in values of pollen types originating from upland tree species in two neighbouring and partly synchronous sections, located in the residual channel and the flood basin of a former Rhine distributary in the central Netherlands, reveal the species composition of an alluvial hardwood forest under natural conditions. Natural levees carried a forest with a high species diversity including Fagus sylvatica, Corylus avellana, Tilia cordata. Betula sp., Acer sp., Carpinus betulus, Fraxinus excelsior and Pinus sylvestris. These results embody the first aimed palaeo-reference system for nature development projects currently in progress on embanked floodplains in The Netherlands.
