Stiffe Caves (San Demetrio ne’ Vestini): discovery of Rhinolophus

Rhinolophus euryale found in the Stiffe Caves

A recent field study in the Stiffe Caves, located in the Sirente Velino Regional Park (San Demetrio ne’ Vestini, Abruzzo), recorded multiple individuals of Rhinolophus euryale, a bat species listed as vulnerable in Italy. This discovery increases the conservation importance of the site at a regional scale.

Who carried out the research and why it matters

The survey was part of targeted monitoring efforts coordinated by academic researchers. Findings like this show how focused studies can reveal local populations of rare species, providing essential data for conservation planning and management.

Conservation and visitor implications

• Conservation priority: confirming a sizeable colony elevates the need to protect the caves and surrounding habitats.
• Ongoing monitoring: regular surveys are needed to assess population trends and identify emerging threats.
• Visitor best practices: stay on marked trails, avoid loud noises and direct lights near roosting areas, and follow guidance from guides and site staff.

Advice for excursion organizers and outdoor operators

Tour guides, nature associations and operators running visits in karst areas should include updated information about sensitive species in their briefings and adopt measures to minimize habitat disturbance. Coordinating with site managers helps balance outdoor recreation and biodiversity protection.

Practical information

The Stiffe Caves are a popular destination for cave visits and speleological tourism. Before planning a trip, check opening times, book guided tours if available, and observe rules set by the Sirente Velino Regional Park to reduce impacts on subterranean wildlife.
