Environmental Enrichment

Although the Animal Welfare Act only requires environmental enrichment programs for nonhuman primates in regulated facilities, many zoos and aquariums are incorporating enrichment into the husbandry routines for all animals. In this section, you will find resources with information on providing environmental enrichment to animals housed in zoos and aquariums.




Enrichment resources for specific species can be found under Exhibit Animal Species. Additional enrichment resources can be found in the Research Animals section of this Web site.
