Forest Successional Dynamics

The vast numbers of plant fossils preserved in a variety of sediments makes it possible to detect repeated associations between species and sediments, sediments that are indicative of particular environments. The patterns of association make it possible to reconstruct not only which species were growing along the river banks, in the backswamps or around, and in, lakes, but also the seral succession of different communities starting from bare soils to mature forests.
