Don't feed wildlife in winter: expert

It might seem helpful, but unnatural diet can cause health problems, biologist says

Putting out food for wild animals in the winter may appear to be good idea, but this habit can do more harm than good.

Wildlife biologists refer to this practice as supplemental feeding and they want people to be aware of the negative impact it can have on animal populations.

“When deer eat carbohydrate-rich food sources during the winter, such as grain or hay, they can die from a process known as rumen acidosis, or bloat,” explains Katherine Conkin, wildlife biologist for the Ministry of Environment, in a news release issued this week.

Saskatchewan's harsh winters often draw animals towards towns and cities as they search for shelter and food. They frequently end up in backyards or in feed storage areas and they come in to contact with residents who are eager to feed them.

Conkin said that deer, like most other wild animals, are resilient and perfectly adapted to survive through the winter without help. She also said that they are well monitored by wildlife protection groups, who are equipped to help animals in a way that is ethical and sustainable.

“The ministry monitors annual winter conditions and adjusts species management strategies to ensure wildlife populations are sustainably managed over the long term,” she stated.

Supplemental feeding can also lead to more subtle imbalances in the natural ecosystem.

Food encourages wild animals to stay in the city, which leaves them more exposed to predators and to disease. Deer are known to decimate city trees and backyard shrubs.

Conkin said that for those who would like to help, it would be more beneficial to participate in a conservation initiative or in a co-operative wildlife management evaluation like the Ministry of Environment's annual hunter harvest survey.

Residents concerned about this issue are encouraged to visit the Saskatchewan Crop Insurance Corporation's webpage to learn about prevention strategies and compensation for agricultural damage.

Feeding animals like deer high-carbohydrate food such as grain can cause severe digestive issues, the provincial environment ministry says.
