The role of plant richness & diversity on ecological equilibrium of rangeland habitats on Alborz Mountain (north of Iran)

摘要：

Ecological equilibrium in rangeland habitat refers to maintenance of vegetation cover and their roots which protects the soil of the ecosystem from erosion.Plant diversity and richness can provide health conditions to maintain an equilibrium ecosystem.L迸ffler (2004), in his research, has shown that change in the composition of soil and plant species due to high grazing pressure.Continuous overgrazing continuously not only increases erosion ( Harden, 1993 ; Molinillo, 1993 ).The present paper has the objective of throwing more light on the influence of biotic and abiotic factors on ecosystem equilibrium.
