Keep wildlife wild – it is BC policy and it makes sense. When humans provide food to wild animals it changes their “wildness”, no matter what species is being fed. There are justifiable reasons to feed wild animals, such as to attract them for capture, but these situations are rare. The consequences of feeding a wild animal unnatural types and amounts of feed can range from mildly irritating behaviour to catastrophic health issues, so understanding the reasons behind this policy is important. The following guidance is specific to ungulates (hoofed mammals) such as deer, elk, or bighorn sheep but the principle of keeping wildlife wild apply to all wild animals. Background Opportunities to come close to wild ungulates are rare but rewarding, especially when the animals are unaware of the humans. Habituation, or increased animal tolerance for close contact with humans, occurs when animals are fed, and with this comes unplanned consequences. Some of the consequences include: 1. Feed Effects Wild ungulates have specialized seasonal food requirements, which they fulfill by eating a wide variety of foods from their environment. Well-intentioned people may quite literally be “killing with kindness” when they provide unnatural food items to wild ungulates. All ungulates are ruminants with specific bacteria in their digestive tracts, specialized to digest their specific diet. It can take weeks for ungulate digestive systems to adjust to new food items. Rapid changes, especially at critical times such as the fall, can result in death, even with rumens full of (unnatural) food. Dry feeds, such as hay, grains or pelleted types, are prepared for domestic livestock and meant to be used with abundant fresh water. Without ready access to water, dry feed can impact in the digestive tract and can kill wild ungulates. Grains, pelleted feeds or surplus fruits are high in carbohydrates/protein/energy and even small amounts can cause digestive upsets that lead to diarrhea, bloating and significant damage to ungulate digestive tracts. 2. Population Effects Wild ungulate populations are naturally limited by a number of factors, including the amount and quality of food their habitat supplies. Animals in poor body condition or with high nutritional needs, such as the young may die when natural environmental conditions and appropriate foods are not present in the right amount and quality to sustain them. Feeding of wild ungulates by humans increases animal density in the short term by concentrating animals around the feed source. Density increases may also occur over tim
