Chimpanzee enclosure program - INTS

A new web-based program has been created to help zoo keepers encourage chimpanzees to behave more like they would in the wild. The design tool developed by University of Birmingham scientists helps create new features for enclosures that are more like the animals' forest homes to keep endangered chimpanzees physically and mentally active and interacting socially. Lead investigator on the study, Dr Susannah Thorpe, said the program aimed to improve the welfare of the chimps in zoos and give visitors a better idea of how they behave in the wild.
