CENTRAL ZOO AUTHORITY<br />
<strong>Barrier</strong> Suggestions<br />
i) It is suggested to provide 5.5m wide and 2.8m deep dry moats as front barrier. As moat<br />
on all sides is both expensive and takes a lot of space, the rear barrier can be 3.4m high<br />
smooth wall. The moat wall should be smoothly plastered.<br />
ii) When there is shortage of space 3.5m chain link mesh of 5cmx5cmx12g with inclined<br />
steel plate of 1m on top can be provided.<br />
iii) Alternatively the moated enclosure can have rear barrier of the type indicated in (ii).<br />
3.3.2 Himalayan black bear/Himalayan or European brown bear<br />
The Himalayan black bear has greatly elongated hair on the shoulders, sides of the throat and<br />
neck. Its fur is pitch-black, sometimes with a purple luster, and there is a large white mark on<br />
the chest, which is sometime Y-shaped. Himalayan black bears inhabit the steep <strong>for</strong>est hills<br />
of the Himalayas during summer, but in winter most of them come down to the lower valleys.<br />
The food consumed by these bears varies with the season. In summer they live largely on wild fruits,<br />
berries and nuts of various kinds. During autumn ripening of corn or maize are raided. Insects are<br />
also part of their diet. There have been cases of human beings mauled or killed by these bears.<br />
