Balearic Islands and Bioparc: Rescue operation for the Pityusen lizard — is it enough?

Answer

Why is the Pityusen lizard disappearing in Mallorca and the rest of the Balearic Islands?

The main threat is invasive snakes that have spread on the islands and prey on lizards and their young. In places where these snakes become established, local lizard populations can collapse quickly, especially if there is no consistent control on the ground.
