Plants found in such areas require large amount of water and are called hydrophytes. Primary succession is a long and drawn out process. Further deposition of soil and plant debris at the bottom reduces the depth of water and makes the habitat less suitable for the pre-existing plants.When the ponds and lakes become too shallow (water depth one to three feet) and the habitat is changed so much that it becomes less suited to the floating plants some other plants which are well adapted to new environment will then come in .Under these conditions, the floating plants start disappearing gradually and their places are occupied by amphibious plants which can live successfully in aquatic as well as aerial environment Important examples are Bothrioclova, Typha, Phragmites (Reed), etc.After a very long time the hydrosere may lead to the development of climax vegetation. The decaying older parts of mosses form a thick mat over the rock surface. The submerged aquatic vegetation develops in the regions of ponds or lakes where water depth is about 10 feet or more. The various stages are:As a result of death and decomposition of phytoplankton and their mixing with the slit, brought from the surrounding land by rain waters and by wave action of pond water, there develops a soft mud at the bottom of the pond.PreserveArticles.com is an online article publishing site that helps you to submit your knowledge so that it may be preserved for eternity. Herbs Stage 5. This type of succession usually takes places in ponds, streams, swamps etc. Phytoplankton stage: In the initial stage of succession algal spores are brought in the body of water. It is also of common occurrence in abandoned agricultural lands. These stages if allowed to progress will eventually result in a climax stage.

Succession without interruption in the swamp, in course of time, produces a terrestrial community. Shrub Stage 6. Niche becomes special and narrower.As the bottom of the lake is raised, a second, or floating, stage follows, characterized by plants like Nymphaea, Polygonum, Limnanthemum and Castalia etc. It involves the processes of colonization, establishment, and extinction which act on the participating plant species. There is an increase in structural complexity.When succession starts on a dry, bare area, it is usually referred to as xerosere. This initiates the next reed-swamp stage.Lichens are succeeded by mosses, which, like lichens, are able to survive in dry environment.

The death and decay of the lichens and old mosses add to the amount of organic matter in the soil and still further increases its water- holding capacity.It starts on a bare rock surface.The process of plant succession consists of nine steps. These mosses are xerophytic in nature and important among these are the species of Polytrichum and Tortula.These mosses form an open community connected with a dense rhizoid system which passes through and binds together a few millimeters of soil particles. (i) Nudation, (i.e., formation of bare soil surface)In his way the habitat is rendered suitable for the growth of higher plants and consequently a new community of herbaceous plants, such as Festuca, Verbascum, Poa, Potentilla and Solidago etc., invade the area. It is also of common occurrence in abandoned agricultural lands. Some blue-green algae, diatoms and bacteria etc. Primary succession on open land may lead to a grassland vegetation rather than a forest climax.They cover the previous lichens and successfully compete with them for water and mineral nutrients. As this mat becomes more thick, it increases the water holding capacity of soil. Increase in non-living matter.In this initial seral stage, a number of submerged aquatic plants, such as Hydrilla, Elodea, Potamogeton, Ceratophyllum, Najas, Vallisnaria, Utricularia, Ranunculus and several algae occupy the shallow pond or lake, which, accumulating after death and decay, gradually raise the bottom of the pond or lake. There is a decrease in net community production.The newly arrived plants interrupt with the existing ones. This is called as climax association for the region in question.The plants of climax community propagate and maintain the character of the community unless the climate changes or community is disturbed by man, fire or some other agency.Due to limited resources, species show both inter and intraspecific competition. Here the pioneer plants usually have succulent leaves and stem e.g., Suaeda maritima, Acanthus ilicifolius, Chenopodium, Basella and some species of Asclapias.3. Animal communities would include the fishes, the water beetles, and the fresh water concentrates.By the time of disappearance of marshy vegetation, the soil becomes drier for most time the year. After their death and decay, the water level decreases and this new habitat’ replace these plants giving way to another type of plants.As succession continues in such areas gradually the environment becomes drier.
