Ecological Succession – Dr Manoj Singh – Department of Zoology
What is Ecological succession? Ecological Succession comprises of two words, Ecology means our environment and succession means how the system moves from one stage to another stage. Succession is of 2 types: Primary Succession and Secondary Succession. Primary Succession means sort of changes occurring in environment where previously no organic matter was available or occupying lifeless ground. Secondary Succession means Re-establishment of particular area where already some organic content was available. For example, after volcanic eruption, after some years area will be occupied by primary community. The first community which occupies the area is pioneer community. This pioneer community includes mosses, lichens which require negligible or less amount of soil for growing. These primary community of lichens will be replaced by another kind of community in due course of time due to processes done by pioneer communities more and more organic content will be deposited in that area and this results into development of soil and this soil will give rise to next level of communities which can be grasses, these grasses will be there for a due course of time and these grasses will be known as Seral stages. Seral stages are all those intermediate stages in due course of time until the system reached the climax community. The seral stages prepare the ground for the climax community. The climax stage is the final stage and it is the most stable stage of the ecosystem. Overall you can see that it started with lichens in the pioneer community and moved to shrubs or grasses in the seral stages and ends with trees in the final stage or climax community.
