Sand lizard

The sand lizard (Lacerta agilis) is a member of the Squamata order and the Lacertidae family. While generally viewed as a beneficial insectivore, it can occasionally exhibit pest-like behavior in agricultural settings, particularly when populations reach high densities.

The primary damage occurs in vegetable gardens, greenhouses, and nurseries. These reptiles can cause significant mechanical damage to seedlings, young sprouts, and low-growing fruits like strawberries by trampling them and burrowing near the plant root systems.

The life cycle and biology of the species are highly dependent on soil temperature. Females lay eggs in shallow burrows excavated in loose soil, often within garden beds. Their activity period coincides with the most sensitive stages of plant growth in the spring and early summer.

The nature of the injury includes jagged bites on foliage and fruits, which significantly reduces the aesthetic and commercial value of the crops. Furthermore, these wounds can serve as entry points for secondary infections such as fungal rot and opportunistic bacterial pathogens.

Control measures emphasize non-lethal exclusion techniques. Recommendations include installing fine-mesh physical barriers around plots, using coarse mulch like gravel to discourage burrowing, and eliminating habitat sites such as rock piles or debris within the agricultural area.
