The mosses increase the amount of solid and the death and decay of the older mosses often produce may on the rock surface. This mat has great water holding capacity. Many herbs first short lived annuals and later biennial and perennial, and xerophytes grasses make their appearance. The roots of these plants accelerate the process of rock disintegration. The soil increases and so does humus due to the death and decay of these plants. Eveaporation from the soil deceases and humidity increases.
1.Shurb stage:- Xeric shrub new appear. The herbaceous plants of the preceding stage now shaded, tend to disappear. The roots of the shrub further corrode the rock which is now more of less completely covered with soil. The solid is further enriched by humus formed form fallen leaves and strings. The soil is shaded and evaporation from it reduced. Wind movement is retarded and humidity increased. All these condition are favorable for the growth of trees and unfavorable for the former processors of the land which disappear.
2.Climax forest:-The first species of trees to appear xeric. Their growth is stunted and they are for spaces. Therir seedlings are shade intolerant. More solid is formed fom the wealthering of rocks and the humus. Moisture gradually increases. Humidity also increases. The trees now become taller and their growth denser. Under their increwssing shade, the light demanding shrubs and earlier treesgives place to more shade tolerant and mesophytic species of trees. A new herbaceous and shurubly vegetation adapted to the humid air and a mossture and richer soil, develops in the shade of the forest floor.
From these we know that succession is convergent. Whatever the condition of initial habitat.
Beginning as a hydrosere or xerosere. The succession in the above cases ends in a mesophytic forests.
It will also be seen, that a succession whether a hydrosere or xerosere is more or less characterised by a similar series of stages.
These are nudation or formation of bare area.
(1) Migration.
(2) Excessive establishment of and maturation of the colonizing species.
(3) Aggregation.
(4) Reacsion.
(5) Competition.
(6) Stabilisation.
(7) Climax.
