Natural plant succession was evaluated after five growing seasons. Three successional patterns were identified on the basis of plant community characteristics using cluster analysis, and were related to sub­ channel, and/or old terraces and channels, and processing the gravel to remove the gold.

The following points highlight the top two types of succession in plant communities. The types are: 1. Succession on a Bare Rock (Xerarch) 2. Succession in Aquatic Environment (Hydrarch). Type # 1. Succession on a Bare Rock (Xerarch): For example, in the succession from bare rock, there must first be the long process of rebuilding the soil.

Plant Succession: Introduction, Process and Types Botany

According to Odum, “plant succession may be defined as an orderly process of community change”. In the words of Salisbury, “Plant succession is a competitive drift in which at each phase until the climax the constituent species render the habitat more favorable to their successors than to themselves.”

Mar 28, 2020 Definition. Ecological succession is a process where one plant community changes into another plant community. It involves the immigration and extinction of species coupled with changes in the relative abundance of different plants.; Succession occurs because, for each species, the probability of establishment changes through time as both the abiotic environment (e.g. soil

5. Succession can be viewed in several stages called seral stages. Each seral stage makes up a different type of plant community. These stages if allowed to progress will eventually result in a climax stage. A climax stage is a self-perpetuating community that is relatively stable over several generations of the dominant plant species. An

INTRODUCTION AND PROCESS OF PLANT SUCCESSION

Plant succession can be defined as the process of gradual replacement of one plant community by another plant community which is of stable type. It occurs over a period of time. The first plant community which develops in a bare area is known as pioneer community and the last invading community is called the climax community.
