8 - Animals and Their Enclosures

Summary

This chapter discusses the design of zoo enclosures and briefly considers important stages in the history of zoo design. Animals must be safely contained within zoos and the nature of the containment varies between species. From time to time containment methods fail and animals escape, sometimes with fatal consequence for them and the people they encounter. There is an ongoing debate about the appropriate amount of space required for some species, especially large carnivores and other wide-ranging taxa. Minimum space requirements for taxa are arbitrarily determined, and usable space and enclosure shape should be considered when enclosures are designed. A number of studies have examined enclosure use by zoo animals, the need for shade and an appropriate substratum. Visitor behaviour may affect enclosure use in some taxa. Enclosure design is a compromise between the need that animals have to avoid the gaze of the public and the desire of visitors to see the animals.
