A recent study warns of potential health risks to humans and animals when homeless individuals are compelled to take refuge in the same secluded areas as urban coyotes. The research, published in Frontiers in Ecology and the Environment, focused on Edmonton’s river valley to investigate the interaction between homeless encampments and urban coyotes.
The study conducted by the Edmonton Urban Coyote Project, a collaborative research endeavor led by the University of Alberta, revealed a close proximity between unhoused individuals and coyotes. This situation leads to competition for space and resources, creating a hazardous environment that heightens the risk of human-coyote conflicts and the transmission of infectious diseases.
Lead author of the study, Sage Raymond, described the scenario as a detrimental cycle for both coyotes and homeless populations. She expressed concerns that similar dynamics may be occurring in other North American cities where poverty and urban coyotes coexist.
The study highlighted the increased dangers faced by individuals sleeping near coyote dens, including the elevated risk of dangerous encounters with the animals and potential exposure to infectious diseases prevalent among coyote populations. Encampments near coyote habitats can lead to displacement of these animals, fostering aggression and nuisance behavior towards nearby communities.
Rather than advocating for crackdowns on homeless individuals or coyote culls, Raymond emphasized the need for targeted conservation efforts, awareness campaigns, and improved medical care accessibility for vulnerable populations. The study, drawing on 15 years of research by the Edmonton Urban Coyote Project, underscored the significant overlap between homeless encampments and coyote habitats in Edmonton’s river valley.
Colleen Cassady St. Clair, a wildlife biologist leading the coyote research project, emphasized the ecological risks posed by encampments attracting coyotes, facilitating their access to human food, and diminishing their wariness towards people. The study also raised concerns about the transmission of diseases from coyotes to humans, particularly alveolar echinococcosis, a parasitic infection spread through tapeworms.
Darcy Visscher, a biologist specializing in urban ecology, highlighted the heightened infection risk faced by Edmonton’s homeless population due to the prevalence of alveolar echinococcosis among coyotes. He stressed the urgent need for increased awareness, local infection rate assessments, and enhanced outreach efforts with frontline agencies to address this public health concern.
The study recommended health-care programs for diagnosing infectious diseases, provision of hygiene supplies for encampments, and education on safe techniques to deter coyotes. St. Clair emphasized the importance of secure housing as the ultimate solution to mitigate the vulnerabilities faced by homeless populations living in proximity to urban coyotes.
