Impacts of Installing New Habitat Structures on Mammal Welfare

Michigan summers are well-known for their heat and humidity. Just like people, animals may seek out comfort in shaded areas during periods of high heat. A selection of habitats at the Detroit Zoo are slated to be renovated with added structures that may provide shade in the summers, heat and shelter in the winter, and/or climbing opportunities. For less cold tolerant species like elands, these structures may allow the animals to spend more time in their outdoor habitats in colder months. For great ape species like gorillas and chimpanzees, structures that supply both shade and climbing opportunities may offer healthy behavioral opportunities while also improving guest visibility of the animals. In preparation for the installation of these structures, CZAAWE staff conducted baseline observations of the animals with special attention to their behavior, space use, and time spent in shaded areas. As structures are gradually completed and installed in habitats, we are continuing observations to assess how animals utilize the new structures and resulting improvements to animal welfare.
