Climate projections for 2050 expect Puget Sound regional temperatures will likely increase by 2.9-5.4 degrees Fahrenheit, temperatures more suitable for a mosaic of fire-resilient landscapes such as prairies, grasslands and oak savannas. Through fire, Indigenous people of this region have stewarded these landscapes since time immemorial. But because of settler colonialism and its legacy, these ecocultural landscapes are increasingly disappearing. This thesis argues that landscape designers must decolonize our methods by asking two questions in order to actively engage in prairie revitalization and Tribal co-generation surrounding prairie revitalization. First, how can a decolonizing design framework support the subsequent fire management of prairies in both wildland and urban areas? Second, how can a decolonizing design framework disrupt then deepen landscape architecture to support fire-dependent prairie habitat revitalization within the Pacific West? I propose the Decolonizing Design Framework (DDF) which includes five practices that can potentially integrate within existing landscape design methods (site analysis, conceptual design, participatory design, design-build and landscape management). The five practices are: (1) to honor Tribal sovereignty, 2) to respect the personhoods of biotic and abiotic life that exist on any given site, 3) to co-generate with a Tribe on shared climate adaptation goals, 4) to center long-term care of the land, and 5) to value multispecies epistemologies. I then implement and analyze the DDF in two case studies, the Camas Monitoring Project on the University of Washington – Seattle campus and the UW-Karuk Klamath Project, and present the findings through an autoethnographic method.
