A need to develop creative practices in child therapy, which address elements of environmental and therapeutic sustainability, is evident. Practices that are accessible, affordable, adaptable, and cross cultural offer therapeutic options that are applicable in a range of contexts. This study explored the potential for nature-based material used in therapy, to facilitate narrative identity development. The therapy process preceding the study entailed the use of an Embodiment Projective Role (EPR) ideas for narrative play therapy, incorporating nature as metaphorical material in exploring identity. As a descriptive qualitative study the collaborative narrative inquiry allowed for an account of identity development through the co creation of a significant statement of self research document. The inquiry into six children's identity documents, differing in age and gender, yielded intentional states of being as identity conclusions. Statements of what was done, statements of knowledge about self, and statements of how their identity informed decision making, were made. Identity conclusions were reached by every participant and the knowledge that was co created resulted in rich feelings across all participants. Participants acknowledged the sustainability of the therapeutic process through concrete natural reminders. When engaging in revisiting conversations with their caregivers, it was evident that each participant had experienced changes that enriched their daily life experiences following the research. The research fulfilled objectives of contributing knowledge of alternative, sustainable therapeutic resources and creates opportunities for continued research and practice in narrative nature based play therapy.
