Chronic Wasting Disease

Chronic Wasting Disease (CWD) is a fatal prion disease affecting cervids such as deer, elk, moose, and caribou. First detected in British Columbia in January 2024, CWD poses risks to wildlife populations, ecosystem health, and communities that rely on cervids for food or cultural practices. 

This project is developing a Genomics Pillar as part of BC’s CWD management program, using population and landscape genomics to understand deer movement, population structure, and susceptibility to disease. By combining a systematic review of CWD management approaches, genomics-based tools, and stakeholder engagement, we aim to guide evidence-informed management strategies, strengthen disease surveillance, and build long-term provincial capacity to respond to CWD effectively and sustainably – protecting wildlife, supporting communities, and building a model for adaptable disease management across species and landscapes.

Outcomes

  • Understand and evaluate CWD management strategies

    Through a systematic literature review, we will identify and assess the effectiveness of approaches used to manage CWD, providing insights to guide evidence-based interventions in BC. 

  • Characterize deer populations and access CWD risk in BC

    We are using populations and landscape genomics to understand deer population structure, movement, and potential susceptibility to CWD. These insights will help prioritize management actions and design interventions that are tailored to local ecological conditions. 

  • Identify barriers and opportunities for implementing a Genomics Pillar for CWD management

    Engaging stakeholders and rightsholders across sectors, we will develop a strategy for long-term integration of genomics into CWD management. This will support sustainable, evidence-informed decision-making and strengthen provincial capacity for ongoing disease monitoring and response.
