Evidence of declining well-being and increasing rates of depression and other mental illnesses has been linked with modern humans’ separation from nature. Landscapes become therapeutic when physical and built environments, social conditions, and human perceptions combine. Highlighting the contextual factors underpinning this separation from nature, this chapter outlines three Australian case studies to illustrate the links between therapeutic landscapes, restorative environments, place attachment, and well-being. Case study 1, a quantitative study of 452 park users near Melbourne, Victoria, focuses on place attachment and explored the links between pro-environmental behaviour and psychological well-being. Case study 2, a small pilot mixed-methods study in a rural area of Victoria, explores the restorative potential of hands-on nature-based activities for people suffering depression, anxiety, and social isolation. Case study 3, a qualitative study of users’ experiences of accessing hospital gardens in Melbourne, highlights improved emotional states and social connections.
