ABSTRACT

Ecosystem is always dynamic due to gradual change of composition and fluctuations are due to many factors including biotic intervention. Ecosystem components are biotic and biotic but many individual components play a crucial role to develop ecosystem tuned though complete index value or ordination is static as composition is dynamic. Therefore to explain the structure and composition ordination study is essential. Many exotic alien species have been recorded here which might be a cause of loss of local floral elements time to time. Therefore individual status study and its ordination is a prime focus study on the basis of natural sal forest in Nayagarm of Jhargram district in West Bengal. Hope that this could be a boon to study health index in details for the study of faunal composition. The interdependency and species richness study could be a second step of study depending on the preliminary study. So, students, teachers, environmentalists and policy makers would be benefitted through this study. Ordination of vegetation and its structure is therefore a new study to manage the environment on a quantitative basis.
