Kinds and Rates of Changes in Vegetation and ChronofunctionsTable I). In fact, long-term plant successions must overlap in time the shorter term changes in vegetation. For instance, the range manager’s “trend” is a loose usage of the idea of plant succession, and trend in range condition has always been difficult to separate from fluctuation in condition due to short-term climatic cycles.

The Use of the American General Land Office Survey in Syndynamical Vegetation Analysis native vegetation. Over most of the continent few fragments of the pre-settlement forests remain. These few are widely scattered and of limited value for ecological interpretation. Even before European settlement the American Indian was responsible for changes in vegetation, particularly through the use of fire.

Types of Successionhe complexity of vegetation change has been revealed to us in ever-greater detail since the turn of the century when Cowles (1899) and later Clements (1936) formally defined the phenomenon of community replacement and suggested that the combined forces of the environment were conducive to a sort of convergence which they called the climax.

Some Principles of Classification and of Terminology in Successionsal steps in any way by attributes of species composition. This differentiation may be only a slight diversity in dominance or coverage (Bedeckungsanteile) of certain species, but can also be a great qualitative difference by abundant occurrence of species totally absent in the preceding or following stage.
