The Challenge
This Natura 2000 site (code GR4220016) is famous for the thousands of moths that gather every summer in its lush, shaded ravine. Yet, in recent years, the population has been threatened by declining water availability, vegetation loss, and hotter, drier conditions due to climate change.
The Solution
The Cyclades Preservation Fund (CPF), funded by the Greek Green Fund, is launching an ambitious conservation initiative to protect and restore the Valley of Butterflies on Paros — one of the most remarkable biodiverse ecotopes in the Cyclades and home to the priority moth Euplagia quadripunctaria (Jersey Tiger Moth).
Project goals
- Restore the microclimatic and hydrological conditions that sustain the Euplagia quadripunctaria population.
- Improve water management through the modernization of traditional holding tanks and the installation of an efficient closed system.
- Increase vegetation cover and shaded areas by planting native trees and key host plants such as ivy (Hedera helix).
- Pilot innovative humidity measures, including a drip irrigation and misting system.
- Engage the local community, scientists, and visitors in understanding and safeguarding this fragile ecosystem.
Planned actions
- Research and monitoring — field surveys and a scientific report on habitat requirements and trends.
- Water infrastructure restoration — upgrading tanks and pipelines to secure water flow.
- Drip irrigation and misting pilot — to maintain humidity during critical summer months.
- Plant propagation and replanting — with native and moth-favoured species from local seed stock.
- Tree planting — increasing canopy cover and microclimate stability.
- Public event — sharing results and best practices with residents and stakeholders.
- Communication and outreach — a dedicated webpage and updates.
- Project management and evaluation.
The program is implemented by the Cyclades Preservation Fund in collaboration with the Mediterranean & Forest Ecosystems Institute (ELGO “DIMITRA”) and the private owners and managers of the site.
