Silent Invasion in Mallorca: How Foreign Snakes Throw the Island Out of Balance

Answer

What non-native snakes are now showing up in Mallorca and why are they a concern?

Mallorca is seeing species such as the horseshoe snake, Montpellier snake, and green-yellow snake in new contexts. The Balearic Islands evolved with few predators, so these newcomers can disrupt native wildlife and food chains. Human activity—horticulture, the pet trade, tourism, and freight—increases their chances of spreading, making the issue gradual but real.
