Control of Invasive Species in Ibiza and Formentera

The plan focuses on eradicating threats to biodiversity in Ibiza and Formentera

What does it consist of?

The invasion of exotic species such as Pennisetum and the horseshoe snake has prompted a monitoring and control plan in Ibiza and Formentera. The plan, which has now been completed, has received public funding and is part of the archipelago’s environmental conservation strategy.

The project

Invasive species are one of the most persistent and complex threats to global biodiversity. In the Balearic Islands, and especially in island ecosystems such as those of the Pityusic Islands, its impact is amplified by the fragile ecology of the environment. In response, the Balearic Government has developed a specific plan for action in Ibiza and Formentera, focusing on the monitoring, eradication and control of major invasive species detected in recent years.

The project, led by the Directorate-General for Natural Areas and Biodiversity, has focused its efforts on specific species such as the Pennisetum, a grass that easily spreads, and two species of snake: the horseshoe snake (Hemorrhois hippocrepis) and the ladder snake (Zamenis scalaris). These snakes, introduced accidentally, threaten native lizard populations, the animal representing the Pityusic Islands.

Implementation has included detection, trapping, elimination and control of outbreaks, together with collaboration from local agents and information campaigns to minimise social alarmism. Although they pose no risk to humans, these species cause concern among residents and tourists, especially during the peak months.

With a budget of more than €856,000, the plan falls under a public conservation policy that prioritises the recovery of native ecosystems and the protection of endemic species. Monitoring results will make it possible to consider future actions based on the evolution of the invasive populations.
