The səlilwətaɬ Tsleil-Waututh Nation Collaborative Shoreline Adaptation Project addresses the challenges of sea level rise and shoreline erosion along Burrard Inlet. Grounded in Indigenous knowledge, the project merges traditional stewardship practices with modern, nature-based solutions to restore ecosystems, enhance food security, and protect cultural and archaeological sites. Community engagement has been central, guiding the vision and adaptation strategies to ensure they reflect Tsleil-Waututh values and priorities. The project identifies critical areas for intervention, such as the Maplewood Mudflats and Whey-ah-Wichen, proposing measures like salt marsh restoration, erosion control, and habitat enhancement. By collaborating with multiple stakeholders, including government and environmental organizations, the initiative promotes resilience and sustainability while reconnecting the Nation to its shoreline. This work sets the stage for phased implementation, offering a model of integrative and adaptive coastal management that prioritizes cultural identity, ecological health, and community well-being.
