Ursidae

Susceptible crops: Bears frequently target cereal crops, especially oats, wheat, and corn. Sweet corn and field corn are particularly vulnerable during the milk and dough stages. Furthermore, orchards, berry patches, and honeybee apiaries are frequent targets for bears seeking high-calorie food sources.

Biology and life cycle: Bears are solitary animals with an annual cycle dominated by pre-hibernation feeding. From late summer to autumn, they exhibit hyperphagia, a period of intensive eating. This timeframe coincides with the ripening of many crops, leading to increased pressure on agricultural lands during the harvest season.

Character of damage and impact: The damage is twofold: direct consumption and physical destruction. By trampling through fields, bears flatten crops, causing severe lodging and making mechanical harvesting difficult. In orchards, they often break limbs and tear down fruit, potentially killing younger trees or severely reducing their long-term health and yield.

Control measures: Effective management of bear-related damage involves:

• Installing electric fencing, which is the most effective deterrent for field and apiary protection.
• Using acoustic and visual deterrents, such as sirens, motion-activated lights, or radio playback.
• Employing chemical repellents that target the bear's acute sense of smell.
• Maintaining clean farm environments to avoid attracting wild animals with food waste or carrion.
