How are animals contained in open-range zoos without traditional cages?

Open-range zoos, which have been established in rural settings since the early 1930s, do not rely on traditional cages to contain animals. Instead, these facilities utilize large paddocks that simulate more natural environments.1

To keep animals within these designated areas while maintaining an open appearance, zoos employ several containment methods:

• Moats: Both water-filled and dry moats are used to create physical barriers that prevent animals from crossing into visitor areas or other enclosures.1
• Fences: Wire-mesh fences are frequently used to secure the perimeter of paddocks.1
• Safari-style management: In some modern parks, animals are kept in expansive paddocks where visitors drive through in vehicles. This approach mimics the experience of African nature reserves, though it requires strict safety protocols to protect both the public and the animals.1

These environments allow for both single-species exhibits and complex, mixed-group habitat displays. When managed by experienced staff and specialized veterinarians, these open-space facilities serve as vital centers for the breeding of endangered species.1
