As ecosystems in coastal British Columbia continue to suffer from the effects of overabundant black-tailed deer, a study by UBC Forestry, in collaboration with Coast Salish Nations, presents effective management solutions for the Southern Gulf Islands. The research indicates that Indigenous-led hunting is the most successful and cost-effective method for mitigating deer overpopulation while addressing ecological and cultural needs. It emphasizes the importance of integrating Indigenous and Western knowledge systems in wildlife management.
Dr. Tara Martin’s study, published in People and Nature, reveals that black-tailed deer populations have surged up to tenfold over the past century due to factors such as altered landscapes and a lack of natural predators. This increase has led to severe overbrowsing, hindering forest regeneration, reducing biodiversity, and harming cultural connections to the land. The consequences are dire, particularly for endangered ecosystems like the Garry Oak meadow, which faces irreversible damage from overgrazing, and for the deer themselves.
“For most people these islands look beautiful and natural, but they are entirely degraded,” says Dr. Martin. “The change has been so slow, most people don’t recognize this shift. We’ve found hyperabundant deer are one of the major drivers of this change.”
The research explored various strategies for deer management, including Indigenous-led hunting, improving predator viability, hiring deer reduction specialists, implementing birth control, and increasing licensed hunting. Indigenous-led hunting stood out as the most viable option, significantly enhancing the likelihood of achieving both ecological and cultural benefits. In contrast, while other methods may appear cost-effective, they showed limited potential for long-term positive outcomes.
The authors argue that maintaining existing management practices will perpetuate ecological degradation and decision-making paralysis, emphasizing the urgency of action. The study aims to provide a transparent framework for decision-makers worldwide, promoting a balanced approach that considers ecological integrity alongside human well-being in the face of hyperabundant herbivores.
