Abstract
Israel National Nature and Parks Authority (INNPA) conducts a management plan for sea turtles since the 1980s. During more than 30 years, rangers are surveying the Mediterranean coasts, tracking, protecting and relocating loggerhead and green turtles' nests into hatcheries in coastal nature reserves. The hatcheries are protected and during the hatching season, the hatchlings are released by the help of rangers and volunteers. More than 100,000 hatchlings were released so far. In 1999 INNPA established a sea turtle rescue center and every year dozens of wounded turtles are rehabilitated and more than 60% are released back to the wild. The turtles suffer from various injuries that result from fishing activity, pollution, plastic debris etc. One part of the rescue center’s work is raising a breeding stock of green sea turtles. Their offspring will be released to the sea from the hatcheries. An additional activity of the INNPA is sampling stranded sea turtle carcasses in order to collect different data, such as genetic information, population size and distribution.
