A recent study highlights the potential health risks to both humans and animals when individuals experiencing homelessness are compelled to take refuge in the same secluded urban areas as coyotes. The research, conducted by the Edmonton Urban Coyote Project and published in the scientific journal Frontiers in Ecology and the Environment, delves into the relationship between homeless encampments and urban coyotes, specifically focusing on Edmonton’s river valley.
The study reveals that homeless individuals and coyotes often coexist in close proximity, leading to competition for space and resources that can create a hazardous environment. This dynamic increases the risk of human-coyote conflicts and the transmission of infectious diseases from animals to people.
Lead author Sage Raymond from the University of Alberta describes the situation as detrimental for both parties, emphasizing the dangers of coyotes accessing food from encampments and the potential exposure of people to disease agents. The study suggests that this scenario is not unique to Edmonton but likely occurs in other North American cities where poverty and urban coyotes intersect.
The study findings indicate that individuals living near coyote dens in homeless encampments face a higher likelihood of dangerous encounters with the animals and an increased risk of contracting infectious diseases, including a parasite prevalent among Alberta’s coyote population. Additionally, coyotes near encampments may become aggressive and a nuisance to surrounding neighborhoods due to their proximity to human food sources.
The study, which draws on 15 years of research by the Edmonton Urban Coyote Project, reveals that as many as 3,000 coyotes inhabit Edmonton, relying on the city’s river valley as a crucial habitat where homeless encampments are frequently established. Estimates suggest that up to 5,000 people in Edmonton are unhoused, with one-fifth sleeping rough each night, leading to the clearance of over 5,600 encampments by the city last year.
Wildlife biologist Colleen Cassady St. Clair, who leads the coyote research project, underscores the ecological risks posed by encampments that attract coyotes, making them less wary of humans and providing easy access to human food sources. The study also raises concerns about the transmission of diseases carried by coyotes, particularly alveolar echinococcosis, a parasitic infection with severe health implications for humans.
Experts warn that the infection, considered 90% fatal in humans, poses a significant threat to Edmonton’s unhoused population, especially given the parasite’s prevalence in the region. They emphasize the importance of raising awareness, improving outreach efforts, and implementing targeted measures to address the risks associated with human-coyote interactions in urban environments.
The study advocates for health-care programs to enhance infectious disease diagnosis, the provision of hygiene supplies for encampments, and education on safe methods to deter coyotes. Ultimately, the goal is to ensure secure housing for all individuals to mitigate the vulnerabilities faced by those living in encampments.
