Status of Herpatofaunal Diversity of Ramagiri East and West Reserve International Journal of Fauna and Biological Studies 2017; 4(4): 19-25 ISSN 2347-2677 IJFBS 2017; 4(4): 19-25 Received: 15-05-2017 Status of herpatofaunal diversity of Ramagiri east and Accepted: 16-06-2017 west reserve forests of Ananthapuramu district, VV Bala Subramanyam Andhra Pradesh Department of Zoology, Sri Krishnadevaraya University, Ananthapuram, Andhra Pradesh, India VV Bala Subramanyam, YD Imran Khan and A Krishna Kumari YD Imran Khan Abstract Department of Zoology, Jnana Ministry of Environment and Forests, Government of India, recommended an impact assessment study in Bharathi Campus, Bangalore view of the potential adverse impacts of windmill projects on terrestrial species of wildlife resulting from University, Bengaluru, Karnataka, India alternation and damage to habitats. In accordance with the broad terms of reference set by the Ministry, the present Herpatofaunal study was carried out in the proposed area of Windmill project and A Krishna Kumari subsequently listed 30 reptile species belonging to 11 families. Varanus bengalensis and Python molurus Professor, GIS and Remote Linnaeus, 1758 are the two reptile fauna belonging to SCHEDULE-I species of INDIAN WILDLIFE sensing wing, Department of (PROTECTION) ACT, 1972. Totally one year were spent in assessing the distribution of herpetofauna. Geography, Sri Krishnadevaraya Visual Encounter Survey Method was followed for the collection of data. IUCN status of Recorded University, Anantapuram, Herpatofauna are mostly Lower Risk least Concern least concern (LR-lc). In this study only the density Andhra Pradesh, India of identified species was specified and calculated based on the average percentage of sightings representing abundant (70 to 100%), common (50 to 70%), frequent (20 to 50%) and rare (0 to 20%). Anthropogenic activities like Forest fires, killing, hunting, and biotic stress like grazing and browsing are the major threats to the proposed wind power project in the Reserve forest area (East and West) of Anantapur district, Andhra Pradesh. Keywords: Herpatofauna, Anantapur district, Windmill, Reptiles, Anthropogenic activities. 1. Introduction Herpatofaunal studies serve as a model for promotion of effective management actions, with a special focus on areas characterized by a strong anthropogenic pressure [1]. The presence or absence of diversity can be a reliable indicator of environmental health and ecosystem stress. [2] Herpatofauna have been declining more rapidly than birds and mammals . Ramagiri, once known for its rich Gold resources, the second in Andhra Pradesh, is now known for Wind Electricity generation. Non-Conventional Energy Development Corporation (NEDCAP) is interested in tapping the full potential of wind energy as part of meeting the ever-growing demand for power. It is difficult to ascertain whether the establishment of windmills in the wildlife habitat areas of Reserve forests can affect adversely the flora and fauna of the surrounding areas, without conducting any herpatofaunal survey. Further, the literature on herpatofauna does not indicate at any major alterations in the habitat fragmentation resulting in the loss of wildlife, especially herpatofaunal diversity, which can be ascertained as an indicator [3-6] of the negative effects of habitat loss/fragmentation . In view of the studies carried out by BNHS &WII on impact of windmill establishment on wildlife, Forest advisor Committee of Ministry of Environment (FAC), Forests & Climate change, Government of India recommended comprehensive studies to be carried out to assess the potential impact of windmills on the terrestrial species of wildlife. Accordingly, the user agency approached the Department of Zoology, Sri Krishnadevaraya University, with a proposal that it take up a study (as per the terms of references suggested in its letter vide F.No.8-47/2008-FC dt16th March, 2008) across the reserve forests of Ramagiri East and west for assessing the potential impact of Windmills on terrestrial species. The present study was intended to come up with a report on the herpatofaunal distribution, densities, and diversity. Subsequently, the study also Correspondence conducted on land use and land cover analysis with a view of providing precise information on VV Bala Subramanyam Department of Zoology, Sri their occurrence and habitat utilization pattern for proper management and conservation of Krishnadevaraya University, biodiversity. The study also focused on anthropogenic threats associated with the ecological Ananthapuram, Andhra degradation of the study area and offering recommendations for the conservation of natural Pradesh, India habitats. ~ 19 ~ International Journal of Fauna and Biological Studies Recent population studies indicate that there are 6347 provide additional information on herpatofauna of amphibian and 8863 reptile species worldwide [7-8] of Rayalaseema region. which32.5% of all the known amphibians and 22% of reptiles are endangered, while 122 amphibians and 22 reptile species 2.

India is perhaps better characterized as a "continent" rather than a "country", in terms of the biodiversity and biogeography of its floral and faunal resources, being one of the 12 mega-diversity countries of the world. There are innumerable species, the potential of which is not yet known. It would, therefore, be prudent to not only conserve the species we already have information about, but also species we have not yet identified. The greatest damage to natural habitat and wildlife today is due to ever increasing exploitation of land and natural resources. The ever increasing exploitation is resulting in damage, loss and fragmentation of natural areas in all continuously inhabited parts of the world- be it desert region, temperate or tropical regions. Himalayas too suffer with similar trend in resource use. Himalayas hold a significant unit in the Indian subcontinent and are being utilized as supplier of natural resources by humans since the start of the civilization in this region. Later the origin and settlements in and around the valleys depleted the biodiversity values of the entire region.

Conservation biology in the last two decades by Animal behavior in captivity as well as in the wild is negligible, because of lack of research works in that, we have tried to make an attempt on it. Captive facilities like zoos aim to create awareness, carry out research and conserve species particularly the threatened ones. Our study aims at understanding the ethology of Indian Rock Lizard in captive conditions. The work on Blanford’s Rock Agama, which is an indigenous lizard of India, was done in Southern India during the summer season. While such aspects have received some attention in larger animals like mammals and even birds, not much is known about reptilian taxa. In reptiles, postures and positions are described for only certain aspects of behavior like fighting and courtship, but we have analyzed most of the external behavior pertaining to Blanford’s Rock Agama.
