Cover Story: This study measured welfare indicators in Asian elephants during their transition and acclimation to a new zoo habitat designed to meet the species’ physical, physiological, psychological, and social needs. Findings indicate the new habitat’s complexity and flexibility improved overall welfare. Elephants were more active and exhibited more autonomy in choosing environment conditions, and also in choosing whom to associate with socially with evolving herd dynamics, suggesting increased social equity for individuals. All individuals showed adaptive and normal adrenal responses to change and challenge. As wildlife populations increasingly come under varying degrees of human care, this study can provide a model and methods for future investigations relevant to both in situ and ex situ conservation.
