The City of Winnipeg is seeking provincial approval for a controversial method to manage the growing ground squirrel population at ten athletic fields. This approach involves the use of two pesticides, which have raised significant concerns from animal welfare advocates and experts regarding their humaneness and environmental impact.
The Rationale for Control Measures
Winnipeg’s decision stems from increasing damage to athletic fields caused by ground squirrels, which dig extensive burrows that not only disrupt green spaces but also pose safety risks to athletes and visitors. Adam Campbell, a city communications officer, emphasized the need for action, stating that previous seasons have seen fields forced to close due to the extensive rodent damage.
As the proposal suggests, the city plans to utilize Rozol RTU, a bait, and RoCon, an asphyxiant foam, to tackle the issue effectively. Campbell asserts that these methods pose limited risks to other wildlife and humans. However, this claim has been met with skepticism by experts in the field.
Expert Opinions on the Proposed Methods
James Hare, a biological science professor at the University of Manitoba, has voiced strong objections to the proposed rodenticides. He argues that both Rozol RTU and RoCon are not only ineffective but also environmentally harmful. Rozol RTU acts as an anticoagulant, leading to a slow death through hemorrhaging, which could take days to manifest. Similarly, RoCon functions by suffocating the squirrels with an irritant gas, but its effectiveness is questionable due to the complexities of ground squirrel burrow systems.
Hare stresses the concern that many squirrels may suffer prolonged deaths, which he considers unacceptable. The design of the burrows, which consist of multiple chambers and exits, could prevent the gas from accumulating effectively, leading to inadequate concentrations that prolong suffering.
Community Concerns and Alternatives
The community’s reaction has been mixed. Liz Jackimec, general manager of Valour Community Centre, recognizes the dangers posed by ground squirrel holes, particularly for children engaged in sports. While she is generally opposed to pesticide use, she admits that finding a humane alternative has proven challenging.
Previous attempts to manage the population through manual methods, such as filling in holes, have been likened to a game of “Whac-a-Mole,” indicating the persistent nature of the problem. Jackimec expresses a desire for a more effective solution that aligns with humane practices.
Historical Context and Regulatory Framework
This is not the first instance of the city seeking permission to use pesticides for ground squirrel control. Last year, a proposal to utilize a sulfur gas product called the Giant Destroyer was rejected by the province, which urged the city to explore alternatives that prioritize public safety and animal welfare.
Animal advocacy lawyer Krista Boryskavich from the Winnipeg Humane Society highlights the risks associated with the proposed anticoagulant baits, noting that non-target animals could ingest the poison, leading to similar suffering and death. She insists that the city must weigh public safety against ethical considerations regarding animal welfare.
Evaluating Alternatives: The Case for Live Trapping
Boryskavich advocates for live trapping as a more humane alternative to rodenticides. Hare concurs, noting that while live trapping may be more labor-intensive and costly, it avoids the suffering associated with poison. However, the city has deemed live trapping unfeasible due to the stress it places on the animals and the low survival rates post-release.
Timing and Effectiveness of Control Measures
The city has planned to conduct its pesticide treatments from March 2 to October 30, with the bulk of the efforts slated for March and April. Hare emphasizes the importance of timing in population control, suggesting that intervention should occur before the breeding season to maximize effectiveness. He warns that targeting lactating females could leave orphaned young squirrels to die from starvation, further complicating the ethical implications of the chosen methods.
Public Engagement and Final Thoughts
As part of the approval process, the city has published an advertisement inviting public feedback on the proposed ground squirrel control measures. The window for submissions is open until January 28, allowing residents to voice their concerns or support for the city’s plan.
In conclusion, Winnipeg’s approach to managing its ground squirrel population presents a complex interplay of public safety, environmental concerns, and ethical considerations. As the city navigates this contentious issue, the balance between effective control and humane treatment will remain a focal point of debate among residents and experts alike.
