<P> The Nilgiri tahr inhabits the open montane grassland habitat of the South Western Ghats montane rain forests ecoregion . At elevations from 1,200 to 2,600 metres (3,900 to 8,500 ft), the forests open into grasslands interspersed with pockets of stunted forests, locally known as sholas . These grassland habitats are surrounded by dense forests at the lower elevations . The Nilgiri tahrs formerly ranged over these grasslands in large herds, before but hunting and poaching in the nineteenth century reduced their population . </P> <P> As few as 100 Nilgiri tahrs were left in the wild by the early 20th century . Since that time their numbers have inceased somewhat; in a comprehensive study of the Nilgiri tahr population in Western Ghats, the WWF - India has put the population at 3,122 . Their range extends over 400 kilometres (250 mi) from north to south, and Eravikulam National Park is home to the largest population . As per the Wildlife census conducted by Kerala forest department in association with volunteers from College of Forestry & Veterinary Science under Kerala Agricultural University, from April 24 - 28, 2014, number of animals in Eravikulam National Park has increased to 894 individuals . This is the highest ever count recorded in the national park, with the first census in 1996 finding only 640 tahrs . The other significant concentration is in the Nilgiri Hills, with smaller populations in the Anamalai Hills, Periyar National Park, Palni Hills and other pockets in the Western Ghats south of Eravikulam, almost to India's southern tip . A small populations of tahr numbering around 200 are known to inhabit the Boothapandi, Azhakiyapandipuram, Velimalai, Kulasekaram and Kaliyal Ranges in the Kanyakumari district of Tamil Nadu and another small herd of less than 30 animals is known to inhibit Ponmudi hills in Trivandrum district of Kerala </P> <Table> <Tr> <Td> <Table> <Tr> <Td> </Td> </Tr> <Tr> <Td> In Rajamala, Munnar </Td> </Tr> </Table> <Table> <Tr> <Td> </Td> </Tr> <Tr> <Td> Nilgiri tahrs making their way down the mountain </Td> </Tr> </Table> <Table> <Tr> <Td> </Td> </Tr> <Tr> <Td> An adult male Nilgiri tahr, with a pallid harrier (female) </Td> </Tr> </Table> </Td> </Tr> </Table> <Tr> <Td> <Table> <Tr> <Td> </Td> </Tr> <Tr> <Td> In Rajamala, Munnar </Td> </Tr> </Table> <Table> <Tr> <Td> </Td> </Tr> <Tr> <Td> Nilgiri tahrs making their way down the mountain </Td> </Tr> </Table> <Table> <Tr> <Td> </Td> </Tr> <Tr> <Td> An adult male Nilgiri tahr, with a pallid harrier (female) </Td> </Tr> </Table> </Td> </Tr>
