Enclosures are structures meant to contain animals for various purposes such as agricultural production, conservation, recreation, and tourism. Generally, enclosures are comprised of walls, fences, and/or netting that are designed to contain animals within a designated area. Enclosures may also include ponds, streams, or other environmental features to provide a more natural enclosure, depending on the purpose. Enclosures are used to keep animals safe, restrict their movement, provide comfortable habitats, and manage animal populations. They may also be used to protect animals from predators or to keep livestock in a particular area.
