Deadly threats at every life stage
Because of dramatic declines in nesting turtles in the last two decades, leatherback and loggerhead marine turtles are at risk of vanishing from the Pacifi c Ocean. In the Coral Triangle, several factors threaten all turtle species:
• Illegal trade and direct consumption (meat, eggs, shell, leather, curios)
• Bycatch (trawlers, longlines, gill nets)
• Habitat destruction and alteration (coastal tourism, industrial development)
• Pollution
• Disease
• Climate change
At sea, longline fi shing boats are not only pulling out fi sh catches but also thousands of turtles, dead or dying. Today, as few as 2,300 adult nesting leatherback females are estimated to remain across the entire Pacifi c Ocean—hardly enough to sustain the species into the future. In Indonesia alone, it is estimated that as many as 7,700 turtles are killed every year from accidental catch in shrimp trawls and tuna long lines.
A lifetime of great journeys
Marine turtles can undertake migrations of up to12,000 km, but unfailingly come back to the exact same beach where they were born decades ago. For example, the leatherback and loggerhead turtles travel across the entire Pacifi c Ocean between feeding and nesting grounds—a journey that is more than one-third of the way around the world.

With six of the world’s seven marine turtle species navigating the Coral Triangle, WWF is rallying support from businesses, governments and communities for a new rescue plan to save them.
What makes turtles so special?
Turtles are a fundamental link in the
Coral Triangle’s fragile ecosystems.
For example, turtles help to maintain
the health of seagrass beds and coral
reefs which are home to commercially–
valuable species such as shrimp,
lobster, and countless other species.
Not only do turtles have major cultural,
traditional, and social signifi cance, they
also draw visitors from around the world.
The Coral Triangle hosts breathtaking
sites that are visited by turtles and
tourists alike, such as Tubbataha Reef
in the Western Philippines, Sipadan
Island in Eastern Malaysia, Bunaken in
Indonesia, and the Solomon Islands.
For local residents, the fl ow of visitors
who come to admire turtles is a vital
source of income.
T H E C O R A L T R I A N G L E —the nursery of the seas—is the most diverse marine region on the planet, covering 6 million km2 of ocean across six countries in the Indo-Pacifi c region. It is home to 3000 species of reef fi sh and commercially-valuable species such as tuna, whales, dolphins, rays, sharks, and six of the seven known species of marine turtles.

Saving marine turtles—more than just protecting a species
The benefi ts of saving marine turtles go far beyond simply protecting these remarkable species. Conservation efforts will make fi sheries more sustainable and provide benefi ts for small coastal communities. But to be effective, turtle conservation calls for protection of the full range of destinations visited by turtles during their life cycle—places such as beaches, seagrass meadows, coral reefs, open ocean, and migratory pathways that cover several countries. This is exactly what the WWF Coral Triangle Programme is striving to achieve through Marine Protected Areas and reduction of turtle bycatch in fi sheries.

WWF’s Coral Triangle Programme
WWF’s Coral Triangle Programme is focused on securing the health of the region’s natural resources and the millions of livelihoods that depend on it. We are working to ensure that proper environmental, political and socio-economic management is put in place towards:
• Building a sustainable live reef food fi sh trade
• Promoting sustainable tuna fi sheries
• Financing marine protected areas
• Protecting marine turtles and reducing their bycatch
• Reducing the impacts of climate change

Objectives
• By 2020, 50 percent of turtle major nesting, foraging and inter-nesting habitats, and key migratory pathways for priority species in the Coral Triangle are protected.
• By 2020, turtle mortality due to bycatch of leatherbacks and green turtles in tuna longline, and coastal fi sheries near major nesting beaches, is reduced by at least 50 percent against 2008 levels.
