Fallow deer

The European fallow deer (Cervus dama) belongs to the Artiodactyla order and the Cervidae family. While often viewed as a charismatic animal, it is classified as a significant pest when populations exceed the carrying capacity of their natural environment, leading them to forage heavily on agricultural and horticultural land.

These animals are generalist herbivores with a diet that shifts according to seasonal availability. They cause extensive damage to agricultural crops, including winter cereals, oilseed rape, sugar beets, and corn. Their foraging habits are particularly destructive during the late winter months when natural forage is scarce.

The biological success of Cervus dama stems from their social structure and adaptability. They congregate in large groups, exerting intense grazing pressure on specific fields. Their life cycle, characterized by a distinct rutting season in the autumn and birth in the summer, supports rapid population growth if left unmanaged.

The primary economic damage manifests in two ways: direct consumption of plant material and mechanical damage to tree stems. Browsing on the terminal shoots of fruit trees prevents healthy growth and significantly reduces crop yield. Furthermore, bark stripping exposes the wood to pathogens, often resulting in the premature death of orchards.

Protection strategies are essential for sustainable farming. Key measures include:

• Erecting high-tensile wire fencing at least 2 meters tall.
• Applying commercial repellent sprays to sensitive crops and trees.
• Using motion-activated acoustic or visual deterrents.
• Collaborating with local wildlife management agencies to monitor and regulate population density.
