Determination of Keystone Species that Influences the Diversity of Birds Species in the Land of Reclamation and Revegetation of Post-Coal Mining

Abstract

Restoration of biodiversity is one of the successful assessments in the ecological restoration efforts on reclamation and revegetation land. The objective of this study is to determine the relationship between fauna diversity and role of vegetation as a producer. The selected fauna included bird species and the selected vegetation included the fast growing plant of revegetation as well as the lower vegetation growing among the staple crops. The analysis used was DCCA for sub-factor of bird species, shrub species and vegetation role clusters as fauna food producers. The result of the analysis shows that the highest Index Shannon in H₄ (Sengon-rambutan) habitat and in H9 habitat (Oil Palm) is 2.33, while the lowest index is in H₁ that is only one bird species. The species richness from the lowest to the highest is in H₁ (Akasia-plantan [-]), H₁₀ (Ponds [0.6]), H₅ (Trembesi-johar [0.86]), H₆ (Karamunting-shrubs [0.95]), H11 (Fern-Rice [1.36]), H7 (Sengon-karamunting [1.85]), H₂ (Akasia-karamunting [1.94]), H₈ (Rubber [2.01]), H₉ (Oil Palm [ 2.30]), and H₄ (Sengon-rambutan [2.33]). H₆ and H₁₁ have a better visible kind of richness than the P3 & P8 factors. H₅ is more closely influenced by P₂ factor. H₂, H₇ and H₉ are strongly influenced by P₆ and P₇, H₈ and H₃ are strongly influenced by P₄ and are weakly affected by P₂ and P₁. H₄ is strongly influenced by P₁ and less influenced by P₄.
