Sapporo city officials are unable to cull deer appearing in residential areas because trapping the animals may attract predatory bears [1].

This dilemma creates a public safety crisis where residents must choose between the danger of wandering deer and the heightened risk of bear encounters. The city's inability to act on the deer population leaves neighborhoods vulnerable to traffic accidents, and property damage.

Deer have begun descending into residential zones, with witnesses reporting groups of six to seven animals appearing at one time [1]. These herds are frequenting high-traffic roads and neighborhoods where children often walk to school.

"This has never happened before," a local resident said. "I am just worried about when they might collide with children who often pass through here" [1].

City officials explained that the timing of the current season makes traditional trapping dangerous. If traps are set, bears may be lured into the city to hunt the immobilized deer [1].

"During this period, if we were to set traps, there is a fear that bears would appear to target the deer that cannot move, making it difficult to carry out culling," a Sapporo city official said [1].

Local witnesses confirmed that the deer are increasingly comfortable in urban environments, moving closer to homes in larger numbers [1]. The city remains in a deadlock, as the method used to remove the deer introduces a more lethal threat to the human population.

“Trapping deer in residential areas could attract bears seeking immobile prey.”

This situation highlights the complex ecological challenges of urban wildlife management in Hokkaido. When an invasive or overpopulated species like deer enters a city, the solution is not merely a matter of removal but must account for the entire food chain. In this case, the presence of an apex predator like the bear transforms a standard pest control operation into a high-stakes public safety risk, forcing the city to prioritize the prevention of bear attacks over the removal of deer.
