Conservation status: Vulnerable (IUCN Red List)

Nesting behavior: Female loggerheads return to Zante’s beaches every 2-3 years to lay their eggs, typically between May and August.

Green Sea Turtle (Chelonia mydas)

While less common than loggerheads, Green Sea Turtles are occasionally spotted in Zante’s waters.

Key features:

• Heart-shaped carapace
• Small head relative to body size
• Distinctive pair of prefrontal scales
• Average length: 100-150 cm (39-59 inches)
• Average weight: 150-300 kg (331-661 lbs)

Habitat: Green sea turtles prefer coastal areas with seagrass beds.

Diet: Adults are primarily herbivorous, feeding on seagrasses and algae.

Conservation status: Endangered (IUCN Red List)

Detailed Species Profiles

Leatherback Sea Turtle (Dermochelys coriacea)

The Leatherback Sea Turtle is the largest of all living sea turtles and is occasionally spotted in the waters around Zante.

Key features:

• Distinctive leathery skin instead of a hard shell
• Seven longitudinal ridges along the carapace
• Average length: 150-170 cm (59-67 inches)
• Average weight: 300-500 kg (661-1,102 lbs)

Habitat: Leatherbacks are pelagic, spending most of their time in the open ocean. They are rarely seen near the shores of Zante.

Diet: These turtles primarily feed on jellyfish and other soft-bodied organisms.

Conservation status: Vulnerable (IUCN Red List)

Unique characteristics: Leatherbacks are the most migratory and wide-ranging of all sea turtle species. They can dive to depths of over 1,000 meters (3,280 feet) and can maintain a body temperature several degrees above the surrounding water temperature.

European Pond Turtle (Emys orbicularis)

The European Pond Turtle is a freshwater species found in some of Zante’s inland water bodies.

Key features:

• Dark carapace with yellow speckles
• Yellow streaks on head and limbs
• Average length: 15-20 cm (6-8 inches)
• Average weight: 400-700 g (14-25 oz)

Habitat: These turtles inhabit a variety of freshwater environments, including ponds, lakes, and slow-moving rivers on Zante.

Diet: Omnivorous, feeding on aquatic plants, insects, mollusks, and small fish.

Conservation status: Near Threatened (IUCN Red List)

Behavior: European Pond Turtles are known for their basking behavior, often seen sunning themselves on logs or rocks near water bodies.

Balkan Terrapin (Mauremys rivulata)

The Balkan Terrapin, also known as the Western Caspian Turtle, is another freshwater species found in Zante’s inland waters.

Key features:

• Olive to dark brown carapace
• Yellow stripes on neck and head
• Average length: 20-25 cm (8-10 inches)
• Average weight: 500-1000 g (18-35 oz)

Habitat: These turtles prefer slow-moving or stagnant freshwater habitats, including rivers, ponds, and marshes.

Diet: Omnivorous, consuming aquatic plants, insects, mollusks, and small fish.

Conservation status: Least Concern (IUCN Red List)

Unique characteristics: Balkan Terrapins are known for their ability to tolerate brackish water, allowing them to inhabit estuarine environments in addition to freshwater habitats.

Turtle Habitats in Zante

Zante’s diverse ecosystems provide crucial habitats for various turtle species, both marine and freshwater. Understanding these habitats is essential for conservation efforts and appreciating the island’s ecological significance.

Marine Habitats

1. Laganas Bay
   Laganas Bay is the most important marine habitat for sea turtles in Zante, particularly for the Loggerhead Sea Turtle. This 9-kilometer-long bay features shallow waters and extensive seagrass meadows, providing ideal conditions for feeding and mating.

Key features:

• Extensive Posidonia oceanica seagrass beds
• Shallow, warm waters
• Protected status as part of the National Marine Park of Zakynthos

1. Nesting Beaches
   Zante boasts several significant nesting beaches for Loggerhead Sea Turtles:

• Sekania Beach: Often called “Turtle Beach,” it’s the most important nesting site in the Mediterranean.
• Gerakas Beach: A protected nesting area with restricted access during nesting season.
• Dafni Beach: Another crucial nesting site with limited access.
• Kalamaki Beach: A popular tourist beach that also serves as a nesting ground.

These beaches share characteristics that make them suitable for nesting:

• Fine, soft sand for easy digging
• Gentle slope for easy access from the sea
• Minimal light pollution
• Vegetation behind the beach for shade and camouflage

Freshwater Habitats

1. Lake Keri
   This small freshwater lake provides habitat for the European Pond Turtle and Balkan Terrapin. The lake’s calm waters and abundant vegetation offer ideal conditions for these species.
2. Streams and Rivers
   Zante’s inland waterways, such as the Skourtis River, support populations of freshwater turtles. These habitats feature:

• Slow-moving water
• Abundant aquatic vegetation
• Basking spots like logs and rocks

1. Wetlands
   The island’s wetlands, including marshes and swamps, provide crucial habitats for freshwater turtles. These areas offer:

• Rich biodiversity
• Abundant food sources
• Protection from predators

Conservation Status and Efforts

The conservation of turtle species in Zante is a priority, given their ecological importance and the threats they face.

Major Threats

1. Coastal Development: The expansion of tourism infrastructure threatens nesting beaches and coastal habitats.
2. Light Pollution: Artificial lighting disorients hatchlings, leading them away from the sea.
3. Plastic Pollution: Sea turtles often mistake plastic debris for food, causing injury or death.
4. Climate Change: Rising temperatures affect sex ratios of hatchlings and alter nesting behaviors.
5. Boat Strikes: Collisions with watercraft cause injuries and fatalities among sea turtles.

Conservation Challenges and Future Outlook

Despite ongoing conservation efforts, turtle populations in Zante face several challenges:

Climate Change Impacts

Rising temperatures pose a significant threat to turtle populations:

• Altered Sex Ratios: Higher temperatures during incubation lead to more female hatchlings, potentially disrupting population dynamics.
• Beach Erosion: Sea level rise and increased storm activity threaten nesting beaches.
• Changes in Food Availability: Shifts in ocean currents and temperatures affect the distribution of prey species.

Plastic Pollution

The Mediterranean Sea, including the waters around Zante, faces severe plastic pollution issues:

• Ingestion: Turtles often mistake plastic debris for food, leading to internal injuries and malnutrition.
• Entanglement: Discarded fishing gear and other plastic waste can entangle and injure turtles.

Fishing Industry Interactions

While efforts have been made to reduce the impact, interactions with fishing activities remain a concern:

• Bycatch: Turtles can be accidentally caught in fishing gear, leading to injury or death.
• Habitat Disturbance: Bottom trawling and other fishing practices can damage seagrass beds and other important habitats.

Future Conservation Strategies

To address these challenges, several strategies are being implemented or considered:

1. Expanded Marine Protected Areas: Increasing the size and number of protected areas to safeguard critical habitats.
2. Advanced Monitoring Techniques: Using satellite tracking and genetic studies to better understand turtle movements and population dynamics.
3. Sustainable Tourism Development: Implementing stricter regulations on coastal development and promoting eco-friendly tourism practices.
4. Public Education: Enhancing awareness programs to engage both locals and tourists in conservation efforts.
5. International Collaboration: Strengthening cooperation with other Mediterranean countries to protect migratory species.
