**Pengayaan alam sekitar** merujuk kepada amalan memberikan haiwan penjagaan yang terurus dengan dorongan alam sekitar. Tujuan adalah untuk meningkatkan mutu kehidupan seseekor haiwan dengan menambah aktiviti fizikal, mendorong kelakuan semula jadi, dan mengelakkan atau mengurangkan kelakuan stereotipikal. Dalam prinsip, pengayaan boleh bermanfaat kepada apa-apa haiwan yang bijak, termasuk mammalia, burung, dan juga sotong kurita.

Pengayaan alam sekitar boleh diberikan kepada haiwan dalam keadaan berikut:

* Haiwan kurungan di zoo atau institusi yang berkenaan.
* Haiwan di tempat perlindungan.
* Haiwan yang digunakan untuk kajian.

Jenis pengayaan
---------------

Any novel stimulus which evokes an animal's interest can be considered enriching, including natural and artificial objects, scents, novel foods, and different methods of preparing foods (for example, frozen in ice). Puzzles that require an animal to solve simple problems in order to access food or other rewards are considered enrichment. An animal's environment may also be enriched by the presence of other animals of the same or different species. A stimulus can be considered enriching even if the animal's reaction to it is negative, such as with unpleasant scents, although stimuli that evoke extreme stress or fear should be avoided, as well as stimuli that can be harmful to the animal.

Enclosures in modern zoos are often designed with enrichment in mind. For example, the Denver Zoo's exhibit Predator Ridge allows different African carnivore species to rotate among several enclosures, providing the animals with a larger environment and exposing them to each others' scents.

### Amerika Syarikat

The 1985 amendments to the United States Animal Welfare Act amendments directed the Secretary of Agriculture to establish regulations to provide an adequate physical environment to promote the psychological well-being of primates and exercise for dogs. Subsequent standards for nonhuman primate environmental enhancement (including provisions for social grouping and environmental enrichment) are included under Section 3.81 in the Animal Welfare Regulations (9 CFR). Concepts relating to behavioral needs and environmental enrichment are also incorporated into the standards for marine, flying, and aquatic mammals.
