How the Brown or Grizzly bear should be kept »
Traditional bear enclosures are often quite inadequate, and transforming or replacing old enclosures
requires a lot of space and major investments.
Many zoos have therefore reduced the number of bear species kept, to provide more space and higher
quality enclosures for just one or two species.
Existing enclosures of less than 100 m² should be given up as soon as possible.
For two or three compatible non-breeding adults the enclosure should have a
size of at least 300 m². For a breeding pair two enclosures of at least 300 m²
each should be available.
Individual sleeping / cubbing dens of 6 m², for Kodiak and
Kamtchatka bears of 8 m²,are required.
In particular young brown bears are excellent tree climbers, as are most of the
bear species.
The enclosure should therefore be furnished with ample climbing
opportunities and large hollow trees or other cavities to retreat. In larger
enclosures, natural soil with grass cover is recommended.
Older, small
enclosures usually have a concrete floor which should at least in part be
covered with a more suitable substrate such as bark chips.
Brown bears love to bathe and swim.
The enclosure therefore should have a pool of no less that 20 m² and a depth of 1 to 1.5 m.
Belgrade zoo has 8 bears: 4 brown, 2 asiatic black bears and 2 polar bears.
