Lacertidae
The family Lacertidae, commonly known as true lizards, belongs to the order Squamata. While they often act as entomophages in agroecosystems by consuming harmful insects, in intensive horticultural settings, certain species can cause mechanical damage to young plants, seedlings, and small fruit crops.

Significant damage occurs when population density is high in restricted areas such as greenhouses or nurseries. Lizards can damage tender vegetable seedlings, trample crops, and may also bite into ripe strawberries, tomatoes, and other berries, leaving marks that serve as entry points for fungal infections and rot.
The biology of the family includes laying eggs in loose soil, leaf litter, or piles of plant debris. The life cycle depends on climatic conditions; after winter hibernation, lizards emerge in spring to feed and reproduce. High reproductive rates in favorable years can lead to significant concentrations of reptiles on sunny garden beds.
The nature of the damage involves mechanical tissue trauma during foraging or while establishing basking sites. The primary harmful impact is the degradation of the visual quality of produce and the inhibition of seedling growth. Damaged tissues are prone to secondary pathogen colonization, leading to fruit decay and overall reduction in crop yields.
Protection measures are primarily humane and preventive in nature. It is recommended to:
- Restrict access to beds by installing fine-mesh netting.
- Promptly remove organic debris and branches that serve as habitats or hiding spots.
- Use deterrent repellents or modify the environment to be unfavorable (regular soil cultivation, removal of shelters).
- Mulch the soil with materials that are difficult for reptiles to traverse.
