Chinese water deer

The Chinese water deer (Hydropotes inermis) belongs to the Cervidae family within the order Artiodactyla. While often studied for its evolutionary uniqueness, particularly the lack of antlers and presence of tusks, it is increasingly recognized as a significant agricultural pest in regions where it has been introduced, such as the UK.

Biologically, these animals are solitary and territorial, preferring marshy habitats adjacent to agricultural landscapes. Their diet is strictly herbivorous, focusing on grasses and succulent plants, which inevitably brings them into conflict with farming activities when they graze on cultivated fields.

The list of damaged crops is extensive, including winter cereals, various vegetable crops, and young tree plantations. They show a strong preference for tender, protein-rich shoots, making them particularly destructive during the early growth stages of cereal crops, which often requires farmers to implement immediate intervention strategies.

The damage caused is characterized by grazing, which often destroys the growing tips of the plants, leading to stunted growth or total failure of the crop yield. In addition to grazing, the physical activity of deer groups—walking, resting, and interacting—within the fields leads to severe trampling, which destroys the soil structure and breaks plant stalks.

Managing the Chinese water deer requires a multi-layered approach to pest protection. Primary methods include high-tensile wire fencing, which is the most effective physical barrier. Additionally, olfactory repellents and auditory scarers are used to deter animals from encroaching on valuable crops during critical growth periods, ensuring that agricultural output remains protected.
