Ancient wetlands drained in 1930s now restored. Biodiversity monitoring shows waterbird populations increased 10x in 20 years, proving wetland restoration can reverse biodiversity loss.
From Ancient Lake to Arid Farmland
The Pantani di Lentini is a large, semi-artificial lake that occupies the site of a historic wetland once known as Biviere di Lentini. This original lake, formed by the damming of a river in the medieval period, was for centuries a vast, marshy ecosystem. In the early 20th century, large-scale land reclamation projects took place across Italy. Between the 1920s and 1930s, the Biviere di Lentini was completely drained. The primary motivations were to eradicate malaria by eliminating mosquito habitats and to create new agricultural land. This conversion transformed the landscape from a biodiversity-rich wetland into productive farmland, a process that occurred in many parts of Sicily.
The ecological cost of the drainage was the total loss of a significant wetland habitat. For decades, the area remained agricultural. In the 1970s, a project began to re-create the lake, though on a smaller and deeper scale, primarily as a reservoir for agricultural and industrial water. This new iteration, now called Lago di Lentini, has a capacity of 127 million cubic meters and covers a surface area of approximately 10 square kilometers. The reconstruction marked the beginning of one of Europe's most significant wetland restoration experiments.
An Avian Explosion
The restoration of the Pantani di Lentini demonstrates a remarkable ecological recovery. The area, now a Special Protection Area (SPA), has become an important site for birds along their migratory routes. Over 250 species of birds have been recorded here. The site is particularly important for waterbirds; scientific monitoring shows that populations have increased tenfold in the two decades following the restoration. This recovery shows the ecosystem's resilience.
The restored wetland provides ideal conditions for numerous rare and protected species. It is the only regular breeding site in Sicily for the endangered Ferruginous Duck (Aythya nyroca). Other significant species that thrive here include the White-headed Duck (Oxyura leucocephala) and the re-introduced Purple Swamphen (Porphyrio porphyrio). Large concentrations of White Storks (Ciconia ciconia) and Greater Flamingos (Phoenicopterus roseus) are also common. The wetland's location makes it an important stopover for birds migrating along the central Mediterranean flyway between Africa and Europe, with species like the Eurasian Spoonbill (Platalea leucorodia) and the Glossy Ibis (Plegadis falcinellus) using it for resting and feeding. Ongoing studies continue to document the increasing species richness and abundance, documenting the success of the habitat restoration.
💡Fun Facts
The original name for the wetland, "Biviere," is thought to derive from the Latin *vivarium*, meaning a place for keeping live animals, likely fish.
The area is part of the Natura 2000 network, a system of core breeding and resting sites for rare and threatened species across the European Union.
The site is for birds; it provides a habitat for at least 21 species of dragonflies.
During migrations, the wetland can host congregations of over 20,000 individual waterbirds at one time.
The area is a nature reserve with generally open access to trails, but there are no set visiting hours for the entire zone. Access may be restricted in certain sensitive areas or during specific breeding seasons.

Accessibility
The terrain around the wetland is generally flat and open, with some paved roads and easy walking trails. A telescope is highly recommended for birdwatching.
