Mother of the Forest: Contemplating Species Entanglements in a Sequoia Ecosystem is an immersive experience that explores the significance of symbiotic relationships in a sequoia tree’s ecosystem through embodied perspectives of various species. Through this research project, Mother of the Forest inquires: in what ways can immersive experiences represent a sequoia tree’s ecosystem, in order to communicate to users various perceptions of time and space, symbiosis, climate change, and environmental changes over time? Pairing scientific information with speculative design methods, Mother of the Forest applies a speculative fabulation methodology to exhibit theoretical concepts such as “kinship”, “becoming-with”, and “entanglements” in order to have users consider their own role in intertwined ecologies impacted by human activity, resulting in biodiversity decline and climate change.
