You probably mean the stage where creatures in an ecological succession do not change much because the established plants and animals are the ones that finally survived the struggle and suppressed all the unsuccessful rivals. Successful rivals have achieved some sort of balance. We call that the climax community. A typical example would be a well-established forest, especially a tropical rain forest.
Remember that climax communities are nothing cut-and-dried. Sooner or later time and chance happeneth to them all and they are replaced by disturbed or "ruderal" communities where the whole struggle starts over. Even in a climax rainforest when an old tree falls, forming a clearing, ruderal plants take over, growing quickly. It then takes years or decades for the climax vegetation to dominate and smother the ruderal plants.
Note that many climax trees will not take on the typical climax shape, with long, straight, bare trunks and the foliage mainly at the top, unless they have to grow through a shading tangle of ruderal plants. For instance, some forest yellow-woods (Podocarpus) if grown in the open will form shrubby or domed shapes just a few metres tall, but if they have to grow through a tangle of short-lived ruderal plants such as Virgilia, they grow straight and tall.
As you can see, the idea of a mature ecological community is neither clear-cut nor rigid. But it is generally useful.

Secondary succession occurs most often
The number is limited by the amount of energy lost at each trophic level. Most cannot exceed 5.
Secoundary Succession
Ecological succession maintains equilibrium in an ecosystem because everything in that ecosystem works together. When something gets damaged, patches of that ecosystem works until they gradually restore it.
TopographicalExtreme conditions cause abiotic topographical factors, which are mainly involved with secondary succession. Landslides and mudslides are examples of this type of factor because they cause a massive reformation of the landscape. The disturbance caused by landslides and mudslides allows for disturbance-tolerant species to repopulate the habitat.SoilThe soil, an abiotic factor, of an environment affects ecological primary succession greatly. Different species of plants require different soil conditions. Trees tend to be the largest driving organism in this portion of ecological succession. The pH levels of the soil is often affected most by the inhabiting trees and determines what type of plants can thrive there. The type of soil (loamy sand, sandy, top soil with humus, etc.) also plays a large role in what species can inhabit an area. In sandy areas, only a select few species are able to take root and survive. The moisture level of the soil determines what sort of trees inhabit an area. Swampy areas tend to house trees with higher pH level requirements where drier soils tend to house trees with lower pH level requirements.ClimateClimate, an abiotic factor highly involved in both primary and secondary succession, plays a significant role in determining the direction of succession in an environment. If an environment receives a period of low precipitation, it becomes more susceptible to fires caused by lightning. This leads to secondary succession in which fire-resistant and tolerable species thrive and the others die out. Wind has the ability to reform the landscape over time by way of erosion. Winds can also drive wildfires to further cause disturbance. However, when an environment receives high levels of precipitation, it becomes more suitable for certain species that are tolerable of high moisture levels, which is an example of climatic effect on primary succession.Species Interaction and CompetitionThe interaction and competition between species in a particular habitat is a biotic factor of ecological primary succession. When succession begins and the very first species, known as pioneer species, change the environmental structure, new species now tolerable to the new conditions move in. The diversity among the species present is high at this point. However, in time, competition and interaction causes a significant drop in species diversity where the dominant species thrive and the rest die off.Gesabel_Balag02
Pioneer plants are usually present in an area where primary succession begins.
natural selection is a process which selects among different variants of same species created by chance mutations (1 in billion), the best variant is selected and dominates the other variant while succession applies on whole community, not on variants of same species and it leads to finally establishment of most stable community (eg.forest) and eventually eliminate the other (eg.lichen community)
The Pacific Ocean is the most mature of all oceans on the Earth.

There are various movements in New York that were formed for diverse reasons. The Long Island Succession and Upstate succession are the most famous.
