Feeding wildlife in gardens and urban areas is a common practice in many places; however, experts warn that this can pose significant risks.
According to a new analysis by Tufts University in Boston, United States, this can harm both ecosystems and public health.
Professors from the Department of Biology at this institution pointed out that providing food to animals in urban yards has different effects than doing so in natural habitats. Additionally, there are ecological implications and social issues that deserve attention.
The limited benefits and growing risks of this practice
According to Michael Romero, one of the experts consulted, the practice of feeding wildlife in urban areas is not 100% harmful. However, it does have negative effects.
On a positive note, it is known that bird feeders “probably reduce bird stress during the winter.” This happens because they facilitate access to food in cold seasons.
His colleague Michael Reed also added that this practice can foster citizen engagement with conservation: “Many people love birds because they see them at their feeders.”
However, the specialists insisted that wildlife should never be fed in natural environments such as national parks.
This is due to the danger of animals developing aggressive behaviors towards people.
On the other hand, the specialists pointed out that if animals become “addicted to human food,” it is counterproductive for both them and people.
“This is because they start to attack people to get food,” Romero emphasized.
Additionally, the professor also highlighted the importance of avoiding attracting species that carry diseases, such as “skunks and raccoons infected with rabies.” Also, “feral cats and coyotes.”
On the other hand, feeding wildlife such as squirrels or leaving food accessible for them can bring additional problems.
This is because this practice often ends up attracting unwanted animals that are potentially dangerous to domestic safety.
Finally, the accumulation of food scraps in public spaces can attract not only birds but also rodents and other opportunistic species. This increases the risk of pathogen and pest transmission.
The ecological imbalance in urban areas
Reed cited the case of the Canadian goose, which five decades ago did not reside year-round in the northeast of the United States. It currently remains in those areas thanks to the abundance of available grass.
This presence causes conflicts in residential areas. This happens because “these birds defecate all over the grass,” Reed commented, highlighting that the constant availability of food favors the persistence of species in urbanized areas.
The species that thrive thanks to human intervention often displace other native ones. This alters the balance of ecosystems and affects local biodiversity and quality of life.
Various municipalities have begun implementing regulations that restrict or regulate the feeding of wildlife in squares and parks. This effort aims to prevent conflicts and reduce the spread of diseases.
Experts from Tufts University proposed alternatives to encourage the presence of wildlife without resorting to direct feeding:
- Replace traditional lawns with native plants that serve as shelter
- Create natural food sources for pollinators
- Design urban gardens with native vegetation
- Respect local regulations on wildlife
- Promote constant education on environmental impacts
Reed recommended consulting the book Nature’s Best Hope by Douglas Tallamy, which explores approaches based on local vegetation to achieve responsible coexistence.
The responsibility of those who enjoy animal watching in cities lies in finding ways to support biodiversity. It is necessary for them to be sustainable over time.
Thus, the interaction between humans and animals can occur in a framework that benefits both people and urban ecosystems. This contributes to healthier and more diverse cities.
