    Climate Change & Sea Turtle Nesting Beaches Fact Sheet

    Climate change and the resulting sea level rise are threatening key sea turtle nesting beaches around the world. As all seven species of sea turtles are already under threat, loss of key nesting beaches could be detrimental to turtle populations if rapid action is not taken. Read our fact sheet to get the important details from our full report, ‘Deadly Waters: The Threat of Climate Change and Rising Sea Levels to Sea Turtle Nesting Beaches.’

    Climate Change: A Rising Tide

    The current pace of climate change will be faster than anything experienced in the last 10,000 years, and therefore is an unprecedented threat to sea turtles whose populations are already vulnerable from human activities. Specifically, climate change will cause a loss of nesting beaches and coastal habitat through rising sea levels, increased female gender bias in hatchlings, reduced hatching success from high temperatures and increased storm events, decreased or shifting food supply, and changing ocean currents impacting migration.

    Sea Turtle Nesting Behavior

    Sea turtles return to their birthplace to lay eggs, breed and nest. When mature, the female turtles return to their natal beaches to nest. This is problematic if these beaches disappear as a result of sea level rises.

    Key Facts

    1. Hawaiian sea turtles are at risk.
      • 90 percent of green sea turtles (Chelonia mydas) nest in Hawaii on the French Frigate Shoals, part of an atoll located in the Northwestern Hawaiian Islands. This area could disappear due to sea level rise.
    2. Loggerhead sea turtles could lose 43 percent of their nesting habitat in Florida, where more than 10,000 females nest each year. This percentage is based on a model that assumes half meter sea level rise within the next 20 to 50 years.
    3. Texas sea turtles are at risk.
      • Padre Island National Seashore in Texas is the second most important nesting site for the Kemp’s ridley sea turtle in the world, and is vulnerable to storm surges and rising sea levels.
    4. Further research needs to be conducted to survey beach profiles and overlay that data with models of projected sea level rises and storm surges to identify the level of risk from climate change for olive ridley, hawksbill and flatback sea turtles.

    Recommendations

    • Ensure Major Nesting Beaches are Climate Resilient
    • Establish Second Nesting Colonies at Key Species Nesting Sites
    • Reduce Other Anthropogenic Threats to Sea Turtles at Priority Nesting Beaches
    • Document Potential Loss of Major Sea Turtle Nesting Beaches Worldwide
    • Reduce Climate Change Emissions to Bring Carbon Dioxide Levels Below 350 Parts Per Million

    Silky Shark Fact Sheet

    Common Name: Silky Shark

    Scientific name: Carcharhinus falciformis

    Global distribution:
    -One of the three most common pelagic sharks in the world, and most common shark in tropical pelagic fisheries.
    -Present in global tropical waters between latitudes 20° N and S.
    -Inhabits both oceanic and coastal habitat.

    SilkySharkSubBanner

    Facts About Silky Sharks:
    -Name comes from its smooth skin and slim body
    -Commonly reaches a length of 2.5 m (8.2 ft), with a maximum recorded length of 3.5 m (11 ft) and weight of 346 kg (763 lb)
    -An opportunistic predator, feeding on squid, tuna, mackerel, sardines, groupers, and snappers.

    Population Decline
    International consensus agrees on the precarious state of the population by overfishing, judging by the low in relative abundance and reducing size of specimens caught in fisheries where data exist.

    -Total annual catch reported to the Food and Agricultural Organization fell steadily from 11,680 tons in 2000 to 4,358 tons in 2004
    -Declines of some 90% in the central Pacific from the 1950s to the 1990s
    -60% decline off Costa Rica from 1991 to 2000
    -91% decline in the Gulf of Mexico from the 1950s to the 1990s
    -85% decline (for all large requiem sharks) in the northwestern Atlantic from 1986 to 2005
    -The silky shark fishery off Sri Lanka reported a drop from a peak catch of 25,400 tons in 1994 to only 1,960 tons in 2006

    IUCN Red List Category: Vulnerable in the Eastern, Central, and Southeast Pacific, and Northwest and Western Central Atlantic. Near Threatened on a global scale.

    Convention on Migratory Species Status: Listed under Appendix II in November of 2014, and listed under Annex I of the Memorandum of Understanding (MoU) Migratory Sharks in February 2016.

    Threats
    -Greatest numbers of silky sharks are caught incidentally by tuna and mahi mahi longline and purse seine fisheries throughout its range, particularly those using fish aggregating devices.
    -Most-caught species in longline fisheries in the Eastern Tropical Pacific, constituting up to 90% of the total catch of sharks.
    -Large numbers of silky sharks caught by commercial and artisanal multispecies shark fisheries operating off Mexico, Guatemala, El Salvador, Costa Rica, the United States, Ecuador, Spain, Portugal, Sri Lanka, the Maldives, Yemen, and Côte d’Ivoire.
    -Fins from an estimated 0.5 to 1.5 million silky sharks are traded globally per year; it is the second- or third-most common species auctioned on the Hong Kong fin market, which represents over half the global trade
    -The meat (sold fresh or dried and salted), skin, and liver oil may also be used
    -Predominant source of dried shark jaw curios sold to tourists in the tropics

    Recommended conservation actions
    -The IATTC should enact the recommendations of its Scientific Advisory Committee to reduce and limit the catch and implement 3-month fisheries closures
    -CITES should list the Silky Shark on Appendix II and trigger measurable action plans to reduce mortality and reverse population decline
    -Reduce fishing effort in the Eastern Tropical Pacific
    -Release sharks alive

    What you can do
    Sign our petition calling on the Inter-American Tropical Tuna Commission to implement 3-month closures and improve gear types.

    Make Your Own Sea Turtle Costume!

    Materials:

    • 1 or 2 large cardboard box/cartons. I get these from appliance stores or bicycle shops
    • 8 1-2″ wide strips of fabric about 1-2 ft. long. I got fabric from a thrift shop, old sheets or bed spreads work well for this (try to find a color that is similar to your turtle).
    • Quart of exterior house paint (possibly some Z-prime for an undercoat depending on quality desired).
    • A heavy-duty stapler with 3/8″ staples. Stapler needs to be the long handled heavy duty type. Staples longer than 3/8″ tend to bend and come back through the cardboard creating a sharp, snagging hazard.

    Cocos Island Gallery

    Cocos Island National Park in Costa Rica is known worldwide as an ocean haven for spectacular sharks, rare sea turtles, whales and abundant marine wildlife. But even World Heritage status has not stopped commercial fishers from invading these treasured waters.

    Turtle Island is working to demand that Costa Rica protect Cocos Island National Park create a protected area that connects all the way to Ecuador’s waters, northeast of the Galapagos Islands. These two nations could create one of the world’s largest protected ocean zones, and save the endangered leatherback turtle from extinction.

    And now you can help us! We welcome experienced divers who want to participate in our ongoing research to help tag and track sea turtles and sharks in the Cocos Islands. You will get hands-on opportunities to capture turtles and attach satellite and acoustical transmitters and to tag and photograph hammerhead sharks underwater.
