Ibiza snakes: EU urged to consider tree import ban

On Ibiza, in Spain’s Balearic Islands, invasive snakes are spreading and the protected Pityusic lizard is under threat. On 12 October 2026, Ibiza & Formentera Preservation calls on European institutions to examine a permanent ban on large ornamental trees brought from mainland Spain to Ibiza and Formentera. The charity says the trees are the main route by which new snakes reach the islands.

Why the trees matter

Large trees imported for gardens, including centuries-old olive trees, can carry snakes, the charity says. It wants an independent scientific review of existing seasonal restrictions and quarantine rules. It also wants the European Union to assess whether a permanent ban would comply with single-market rules.

Where the lizards remain

The charity wants the Balearic regional government to update its count of Pityusic lizards. The last reference studies were carried out in 2017 and 2022. A new survey would help show where lizards remain on Ibiza, Formentera and nearby islets, and whether protection measures are working.

An internal report commissioned by the charity says current trapping is not enough to reduce snake numbers significantly. It wants an extra trapping plan focused partly on coastal areas near islets, plus early detection and a rapid response if snakes swim to new islets.

The European Commission has expressed concern about the lizard’s conservation status. It says national and regional authorities have primary responsibility for protecting species and tackling invasive ones.
