to be honest I dont think a new sun bear enclosure is needed. I dont see why they cant stay in the jaguar house permanently as it is a good enclosure for them.
Once the bears have moved out of their current enclosure what will go in there or will be be demolished?
And also how many orangutans are at the zoo?
When the bears leave the jaguar enclosure another species will be coming to the zoo.
the present sun bear enclosure (previously tigers) is scheduled for demolition
