Differences Between Fluctuations and Successionsns, as differentiated from successions, are characterized by (a) differently orientated changes in phytocoenoses from year to year or from one period to another one, (b) reversibility of changes, (c) in typical cases stability of floristic composition, absence of invasion of new species.

Diese Forschungsrichtung wird bis heute fortgesetzt und auch detaillierter auf die standörtlichen Gegebenheiten bezogen (z.B. Neuentdeckung von autochthoner Kiefer im Ostmünsterland (Hesmer 1958) und im Pfälzer Bergland).

Mutual Influences Between Plants, Allelopathy, Competition and Vegetation Changestivation. In extreme cases by influences of associated plants, the advantage of a changed environment can be totally obscured. Thus, in vegetation the environmental factors act mostly not directly on the individuals of a plant taxon; their effects are more or less modified by mutual influences between the plants.

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
