For example, cleared forests in the eastern United States progress from fields to old fields with colonizing trees and shrubs to forests of these early colonists and finally to climax communities of longer-lived tree species. The species composition of the climax community remains the same because all the species present successfully reproduce themselves and invading species fail to gain a foothold.

When extensive and well defined, the climax community is called a biome.
- A serial community is a name given to each group of biota within the succession.
- Species composition is stable, and the community has reached equilibrium.
- A climax community is a stable community of a diverse number of species.
When extensive and well defined, the climax community is called a biome. Examples are tundra , grassland, desert , and the deciduous, coniferous, and tropical rain forests. Thus, on a lakefront, grass may invade a build-up of sand. Humus formed by the grass then gives root to oaks and pines and lesser vegetation, which displaces the grass and forms a further altered humus. That soil eventually nourishes maple and beech trees, which gradually crowd out the pines and oaks and form a climax community.
In addition to trees, each successive community harbors many other life forms, with the greatest diversity populating the climax community. Similar ecological zonings occur among marine flora and fauna, dependent on such environmental factors as bottom composition, availability of light, and degree of salinity.
In other respects, the capture by aquatic plants of solar energy and inorganic materials, as well as their transfer through food chains and cycling by means of microorganisms, parallels those processes on land. The early 20th-century belief that the climax community could endure indefinitely is now rejected because climatic stability cannot be assumed over long periods of time.
In addition nonclimatic factors, such as soil limitation, can influence the rate of development. Polyclimax theories stress that plant development does not follow predictable outlines and that the evolution of ecosystems is subject to many variables. The Columbia Electronic Encyclopedia, 6th ed.

What is a climax community? | Socratic
A serial community is a name given to each group of biota within the succession. To understand a climax plant community, you must first understand plant succession which is simply the replacement of one plant community by another. This can occur when soils and sites are so harsh that few plants can survive and takes a very long time for plants to establish a root-hold to begin the process of succession. When destructive agents like fire, flood and insect epidemic destroy an existing plant community, plant establishment can happen very rapidly.
It is obvious that these harsh conditions for plants would take eons for this type of exposed earth to decompose to support higher plants with the exception of the earth slide which would start plant succession fairly quickly.
Secondary plant succession generally starts on a site where some "disturbance" has set back a previous succession. The name usually given to any particular climax forest is the name of the primary existing tree species and or its regional location. To be a climax forest, the trees growing within a particular geographic region should remain essentially unchanged in terms of species composition for as long as the site "remains undisturbed".
Should speculative ecologists conclude that there can never be a climax forest because cyclical disturbance both natural and human-caused will always be a constant in North American forests? The first published discussion s on the existence of climax communities started nearly a century ago with foundational papers written by two ecologists, Frederick Clements, and Henry Gleason.
Their ideas were debated over decades and definitions of a "climax" changed with a greater understanding of a new science called ecology. Political winds also confused the topic with terms like "virgin forests" and "old-growth forests". Others believe that there can never be a real climax community because of constant disturbance over time. Foresters have adopted a silviculturally practical approach when managing large stable communities of climax tree species.
They use and name a "climax" forest to be the final sere in terms of the stabilization of major tree species. These conditions are observed on a human timescale and can maintain specific tree species and other plants over hundreds of years. Share Flipboard Email.
