Elephant welfare in zoological collections is one of the most extensively studied and debated topics in zoo biology, with clear evidence linking space, social group quality and welfare outcomes.
Zoo elephant welfare has been transformed by decades of research demonstrating that space, substrate, social group quality and daily movement opportunities are the primary determinants of welfare outcomes. Elephants on hard substrate without adequate walking opportunities develop chronic foot disease that causes persistent pain and is a leading cause of premature death. Social deprivation from inadequate group size or composition causes psychological harm comparable to documented effects in wild elephants. The best zoo elephant facilities now provide multiple acres of varied substrate, large social groups with age-appropriate composition, and daily active management that supports natural movement patterns. Facilities that cannot meet these requirements cannot maintain good elephant welfare.
