European hedgehog

The European hedgehog (Erinaceus europaeus), belonging to the order Eulipotyphla and family Erinaceidae, is traditionally viewed as a beneficial insectivore. However, in specific agricultural contexts such as berry farming and intensive vegetable gardening, hedgehogs can become significant pests causing economic losses.

The primary crops affected by hedgehogs include strawberries, raspberries, and various low-growing fruits. Hedgehogs forage at night and, while searching for earthworms or larvae, they frequently consume ripened fruits and inadvertently destroy delicate seedling beds, causing root exposure and mechanical damage to plant stems.

The biology of the species revolves around a seasonal cycle of hibernation and intense feeding. Active from spring through late autumn, they prefer sheltered habitats. When these habitats are located within or adjacent to productive fields, the presence of hedgehogs can cause cumulative damage to the crop yield, particularly in greenhouses and berry patches.

The damage caused by hedgehogs is often characterized by bite marks on berries and the displacement of soil or mulch layers. This disruptive behavior not only results in the loss of produce but also increases the risk of secondary infections by bacteria or fungi entering through the open wounds of the damaged fruits and vegetables.

To mitigate the impact of hedgehogs on crops, the following agricultural measures are recommended:

• Installing physical barriers such as wire fencing at least 50 cm high.
• Implementing vertical gardening or raised beds to elevate produce from the ground.
• Maintaining clean fields to reduce attractive nesting sites.
• Utilizing deterrents that exploit the hedgehog's sensitive sense of smell to keep them away from sensitive zones.
