One of the main threats to the western green lizard is habitat loss, and there have been significant population declines in areas where there is intensive agricultural activity. This species is also threatened by other human activities such as burning of scrubland and pesticide use (1). In certain areas, this species is predated by domestic cats and dogs (3).
The range of the western green lizard is increasing in some areas, which may pose multiple threats to native species, including competition for food and nesting sites, and predation of their juveniles. This species may also be a vector of disease, which could be spread to native species (3).
