BARRIER DESIGNS FOR ZOOS 3.4.4 Nilgiri Langur The Nilgiri Langur is found in the South Indian hill ranges in sholas or stretches of dense evergreen forest. They are not confined to forests and may invade gardens and belts of cultivated woodland. Their food is the customary vegetarian food of langurs but the species shows considerable adaptiveness. In planted areas the flowers and buds have become a major source of food. They are known to eat cardamom plant pith and other cultivated plants. They forage for food in the morning, rest at noontime and come out to feed again in the cool evening hours. In the wild Nilgiri langur troops vary in size from 3 to 27 and averaging 8 to 9 animals per troop. Troop organization is on the basis of a single male leader with an adult sex ration of 1.2 female to 1 male. Analysis of Barrier Dimensions NILGIRI LANGUR Width (M) Depth (M)/Height (H) Moat Type Indian Zoos: Indira Gandhi Zoo, Vishakhapatnam N.A. N.A. Dry Arignar Anna Zoological Park, Vandalur 9 2.7 Wet N.A. - Not Available Note: The fences should have smooth overhangs. Barrier Suggestions i) It is suggested that a 7m wide and 3.0m deep wet moat should be used on the visitors’ side. If wet moat is difficult to maintain the dry moat depth should be 5m. The rear barrier can be of 5m tall sunken wall or chain link mesh fence of 5m height with 1m wide steel plate fixed on the top inclined inwards. ii) Chain link mesh fence of the above dimension can be provided all around if space is a limitation. Large toughened glass windows can be provided at few places as viewing window. Of course maximum jumping distance should be maintained from tree branches. 3.4.5 Hoolock Gibbon This is the only ape of the Indian subcontinent and inhabits the rain forest of North-East India. If is arboreal and often lives in tall tree branches and is omnivore. It is capable of precise long leaps. 42
43 CENTRAL ZOO AUTHORITY Illustraion showing cross section of an Island type enclosure for arboreal Primates. It is suggested to house them in islands encircled by wet moat as is afraid of getting in to water. The moat can be 8m wide and 2m deep. 3.4.6 Leopard/Jaguar Though both leopard as well as Jaguar can be housed in open moated exhibit with using tools like solar fencing, this has been found to be risky due to their climbing and jumping ability besides timidity. They are often kept in covered chain link mesh enclosures of appropriate size. They can also be kept in open air enclosures with 5m high chain link mesh fence with 1m wide inclined steel plate fixed on top, leaning inwards. Care should be taken to see that no tree branch is within jumping distance from the fence. Toughened glass windows can be provided for unobstructed viewing Illustration showing the cross section on the use of mesh fence with inclined inward steel plate overhang and providing additional barrier.
