Ecology & Biodiversity

ECOLOGY & BIODIVERSITY: Complete study has been done and given below on the ecological environment of the study area. 1.1.1 Introduction on Ecology and Biodiversity: A natural ecosystem is a structural and functional unit of nature. It has different components, which are interrelated to each other survive by interdependence. An ecosystem has self-sustaining ability and controls the number of organisms at any level by cybernetic rules. The basic purpose to explore the biological environment under Environmental Impact Assessment (EIA) is to assist the decision making process and to ensure that the project options under consideration are environmental-friendly. An ecological survey of the study area was conducted, particularly with reference to listing of species and assessment of the existing baseline ecological conditions in the study area. The main objective of the ecological survey is aimed at assessing the existing flora and fauna components in the study area. Data has been collected through extensive survey of the area with reference to flora and fauna. With the change in environmental conditions, the vegetation cover as well as animals reflects several changes in its structure, density and composition. The present study was carried out in separately for floral and faunal community of core and buffer zone respectively. Need to study: The present study was undertaken with the following objectives: To assess the nature and distribution of vegetation in core and Buffer Zone. To assess the animal life spectra (within 5 km radii) To achieve the above objectives a study area was undertaken. Thedifferent methods adopted were as follows: Compilation of secondary data with respect to the study area frompublished literature and various government agencies; Generation of primary data by undertaking systematic ecologicalstudies in the area. 1.1.2 Selection of Sampling Location for the study of Flora and Fauna: Core Zone: Core zone is the Non-Forest barren area where mining is being done. Core zone is mainly vacant and has few planted species. Buffer Zone:For sampling purpose, buffer zone is further divided in 2 Km and 5 Km. Patches of flora are studied in 2 locations within 2 km , 3 locations within 5 km and 2 Locations within 10 Km. Location of flora is given below. Fauna is recorded randomly. Table Error!

The local inhabitants were also consulted to get extra information. Plant Species are counted and identified within core zone. In buffer zone flora isestimated with the help of line transect and random survey method. Methodology for Study of Fauna: Different species were observed at different timing during the day. Bird: Birds were watched during dawn. Nocturnal and Burrowing animals: After Sunset. Animals: Morning & Evening. 1.1.4 Introduction of the project highlighting the Environmental sensitivity: The proposed project is a graphite mineral mining project. In the zone of 10 Km around the project Palamau National Park is located 5.2 km SSW from the lease area. There is no perennial water body with in the leasehold. The nearest perennial water body is Maila Nadi 0.38 km NE from the mining lease and Kathautiar Lake 0.27 km N. Other perennial river is Auranga River about 5.01 km W and Bahera Nadi 4.90 Km S from the lease area. Koili Nalla is 4.62 km NNW from the lease area. Dhbadih Lake is 2.94 Km NNW from the mining lease area. Forests within the buffer zone are: 1. Nawadih protected forest : 6.80 km NW 2. Polpol protected forest : 7.83 km NWW 3. Betla Reserve forest : 5.20 km SW 4. Betla Protected Forest : 10.2 km SW 5. Rajhara Protected Forest : 8.52 km NW 6. Kewatbar Protected Forest : 15.02 km NW 7. Kechki Protected Forest : 13.08 km NW 1.1.5 Description of Core Zone with flora and Fauna Details: Flora of core Zone: Mining has been commenced in lease area; lease area is vacant with few patches of vegetation. Plantation of few species has been done. Details of the planted species are given in the table below: Table Error! No text of specified style in document.-2, Flora of Core Zone S.
