BARRIER DESIGNS FOR ZOOS Though Himalayan or European brown bear are much larger than other two bears and live at much higher altitude in the Himalayas they can be kept in enclosures with similar barriers. However it will be better to keep them in moated exhibit wit wall on the rear. Barrier Suggestions i) It is suggested to provide 5.5m wide and 2.8m deep dry moats as front barrier. As moat on all sides is both expensive and takes a lot of space, the rear barrier can be 3.4m high smooth wall. The moat wall should be smooth a vehicle. ii) When there is shortage of space 3.5m chain link mesh of 5cmx5cmx12g with inclined steel plate of 1m on top can be provided. iii) Alternatively the moated enclosure can have rear barrier of the type indicated in (ii).

3.3.3 Barrier Recommendations & Comments 37 CENTRAL ZOO AUTHORITY The recommended front barrier design for sloth bears and Himalayan black bears is a U-shaped or V-shaped (flat bottomed) dry moat since these animals essentially inhabit drier environments, i.e. they are not closely associated with water / marshes. The Dehiwala Zoo at Colombo has however, constructed a wet moat as part of its sloth bear exhibit. V-shaped moats look more natural than U-shaped moats and are less expensive to build and are therefore more desirable. If a U-shaped moat is built then the inner edge of the moat is sloped backwards to prevent the animal from falling into the moat. Siltation of the moat bottom is bound to be created by animal movement on unstable moat edges; these should be protected from erosion with underground mesh lining. In very dry regions the sloped edge may have to be constructed out of exposed random rubble stone masonry in which holes can be left for natural scrub vegetation to grow. This is more natural looking than concrete or plastered brick and therefore desirable. The recommended rear barrier design for sloth bears is also a U-shaped or V-shaped (flat bottomed) dry moat if space and a view is available behind the exhibit. If space for a moat is unavailable then high walls may be used. The Hyderabad Zoo is of the opinion that the high wall provided as rear barrier should be made smooth to prevent the animal from escaping and fence should have overhangs. Overhanging rock cliffs are aesthetically desirable as these bears often inhabit rocky slopes - but are very expensive to construct and should only be attempted if a realistic representation is possible. Normally this is beyond the skills of a civil work contractor and has to be executed by a rockwork artist or muralist. The Tirupati Zoo feels that any rock work provided as rear barrier should be visually merged as far as possible with the enclosure/habitat to camouflage it.
