Indigenous Knowledge, Practice, and Belief Systems (IKPBS) are an ecological and cultural framework with which Indigenous communities have (and continue to) adaptively manage their land since time immemorial. In the current context of climate change and colonial forest and fire management in the western US, Indigenously‐led ecological research and cultural revitalization offers a path forward where tribal sovereignty of land stewardship is maintained and the resiliency of natural systems are reestablished. We describe our process of developing an Indigenous‐Directed Research (IDR) partnership to study xánthiip (Karuk for black oak, Quercus kelloggii ), a Karuk cultural focal species, in the context of Karuk‐led forest restoration. We first outline our process of IDR by describing how this partnership was established, research questions and methodologies were co‐developed, IKPBS were centered, and utility to tribal forest restoration processes were prioritized. The primary product of this partnership was a culturally responsive black oak monitoring protocol to assess black oak tree quality over time. We describe how this protocol was developed including conducting semi‐structured qualitative interviews with Karuk cultural practitioners, translating qualitative interviews to field protocol metrics, consulting with research partners, testing for field feasibility, and sharing back to the local community through field training and youth curriculum development. Second, we analyzed plot data collected from the implementation of the black oak protocol using a two‐eyed seeing approach that ensured our ecological findings had cultural relevance for future Karuk‐led forest stewardship. Through this analysis we described the dominant black oak tree typologies based on their traits of importance as identified by Karuk cultural practitioners and research collaborators. All natural resources research takes place on Indigenous land. By outlining the steps of this transdisciplinary IDR partnership, we provide a framework for centering IKPBS, respecting Indigenous land sovereignty, and centering Indigenous leadership in ecological research and knowledge co‐development.

Policy barriers to Indigenous and prescribed fire in California and the United States. This report builds on the original Good Fire report from 2021, but with greater emphasis on federal policy.

Barriers to and Recommendations for Expanding the use of Beneficial Fire.

After a century of fire suppression and accumulating fuel loads in North American forests, prescribed burns are increasingly used to prevent conditions leading to catastrophic megafire. There is widespread evidence that prescribed fire was used by Indigenous communities to manage natural and cultural resources for thousands of years. Wildlife habitat is an example of an ecological response that was actively managed with prescribed burns by Indigenous American peoples and is an important factor in western US forest management planning, restoration and climate resilience efforts. We analysed the effects of modern prescribed burns informed by traditional ecological knowledge (TEK) on the predicted change in elk winter habitat in Karuk aboriginal territory in Northern California between 2013 and 2018 using species distribution and simultaneous autoregressive modelling techniques. Burn types most closely resembling Karuk traditional practices, specifically those incorporating multiple‐year broadcast burns, had significant positive effects on elk winter habitat suitability. Conversely, concentrated burns focused solely on reducing fuel loads had significant negative effects on elk winter habitat suitability. However, areas where these fuel‐reduction burns were combined with multiple years of broadcast burns featured the highest increases in habitat. Synthesis and applications. Our results suggest that transitioning to prescribed burns that more closely follow Karuk traditional ecological knowledge will promote elk habitat in the region. This would be best achieved through continuing to work closely with Indigenous representatives to plan and implement cultural fire prescriptions on a landscape scale, a trend we posit would benefit environmental management efforts across the globe.

The watershed has long captured political and scientific imaginations and served as a primary sociospatial unit of water governance and ecosystem restoration. However, uncritically deploying watersheds for collaborative environmental governance in indigenous territories may inappropriately frame sociocultural, political-economic, and ecological processes, and overlook questions related to power and scale. We analyse how members of the Karuk Tribe’s Department of Natural Resources have leveraged and critiqued collaborative watershed governance initiatives to push for 'ecocultural revitalisation' – the linked processes of ecosystem repair and cultural revitalisation – in Karuk Aboriginal Territory in the Klamath River Basin. We argue for decentring watersheds in relation to other socio-spatial formations that are generated through indigenous-led processes and grounded in indigenous knowledge and values. We explore two scalar frameworks – firesheds and foodsheds – that are emerging as alternatives to the watershed for collaborative natural resources management, and consider their implications for Karuk ecocultural revitalisation. We attempt to bring watersheds, firesheds, and foodsheds together through an ecocultural approach to scale in which water is one among many cultural and natural resources that are interconnected and managed across multiple socio-spatial formations and temporal ranges. We emphasise 'decolonising scale' to foreground indigenous knowledge and to support indigenous sovereignty and self-determination.
