Succession-nothing in plant, community, or ecosystem ecology has been so
elaborated by terminology, so much reviewed, and yet so much the center
of controversy. In a general sense, every ecologist uses the concept in
teaching and research, but no two ecologists seem to have a unified
concept of the details of succession. The word was used by Thoreau to
describe, from a naturalist's point of view, the general changes
observed during the transition of an old field to a forest. As data
accumulated, a lengthy taxonomy of succession developed around early
twentieth century ecologists such as Cooper, Clements, and Gleason. Now,
nearer the end of the century, and after much discussion concerning the
nature of vegetation communities, where do ecologists stand with respect
to knowledge of ecological succession? The intent of this book is not to
rehash classic philosophies of succession that have emerged through the
past several decades of study, but to provide a forum for ecologists to
present their current research and present-day interpretation of data.
To this end, we brought together a group of scientists currently
studying terrestrial plant succession, who represent research experience
in a broad spectrum of different ecosystem types. The results of that
meeting led to this book, which presents to the reader a unique summary
of contemporary research on forest succession.
