Humans can regularly be seen on Mexico’s beaches, umbrella drink in hand. But we’re not the only ones who regularly hit the country’s beautiful sandy coastline. Literally, every sea turtle species on earth nests on Mexico’s beaches, save one that is only found in Australia. That’s why we’re known as the sea turtle capital of the world, and that’s why the way Mexico protects its sea turtles matters on a global scale.

Current Mexican law classifies all sea turtle species as endangered. But unfortunately this really only means turtles are protected from direct harvest—meaning they can’t be killed for their meat, skin, shell or eggs. Yet other factors pose serious dangers, including damage to and destruction of sea turtle habitat. Even nesting habitat, which is particularly important to the survival of these species, was not legally protected.

But not anymore, because in February, a new Mexican law (known as Official Norm-162) took effect, and it offers a whole slate of new protections for sea turtle nesting grounds in Mexico.

Previously, only the most important sea turtle nesting sites have been designated as sanctuaries and natural reserves, which allowed them some level of protection but left the majority of nesting habitat vulnerable.  But now, the new regulation extends habitat protections to all turtle nesting sites. Here are just some of the things that this new and unprecedented regulation has accomplished for sea turtle nesting habitat:

Protecting Native Habitat
The new regulation forbids the removal of native vegetation in the nesting habitat. When coastal vegetation is removed, especially from sand dunes, it allows increased erosion that could eventually destroy nesting beaches. In addition, some turtles like the critically endangered hawksbill sea turtle even prefer to crawl up the beach all the way up to the vegetation to nest.

Putting Out Artificial Lights
The regulation also addresses one of the main factors that disrupt nesting turtles: artificial lights from houses, hotels and roads. These light sources can not only disorient nesting females, but they can be lethal to emerging hatchlings. As they climb their way up from their sandy nest, newly-hatched turtles look for the subtle light reflecting off the surf and waves to orient themselves towards the sea. Artificial lighting can point them in the wrong direction and when you are that young, one wrong turn can force you to use up your limited energy stores, leading to an almost certain death. Even those that eventually make their way to the surf can be too exhausted to swim away, becoming easy pickings for fish and marine birds. For the first time in Mexico, this new regulation calls for moving, changing or eliminating any light sources that illuminates a nesting beach or creates a glow that could disorient the females or hatchlings. These changes won’t happen overnight, but authorities are already informing beachside homeowners and hotels of the new rules.

Off-Road Vehicles
The new regulation also helps address the use of heavy vehicles on the beach. Heavy vehicles may compact sand, destroy nests and eggs, create deep ruts that can become traps for nestlings and basically tear up nesting beaches. No more. From now on, vehicles on nesting beaches have to be less than 300 kg in weight and can only be used for patrolling and management of the nesting site.

Spectators
A less obviously threatening activity also outlawed by the new regulation is the release of newly hatched sea turtles. Many hotels near nesting beaches offer guests the opportunity to be part of the release of hatchlings into the sea. The problem is that they keep the hatchlings in confinement for many days until enough people sign up for the activity. So when they are released after being held in captivity, they are too weak to handle the surf or avoid predators. Hatchlings need to get into the water as soon as possible after hatching so they can use their limited energy to swim away. This tourism practice is now forbidden, and hatchlings have to be released immediately. Also for the first time, those who want to watch sea turtles laying their eggs during nesting season will have to follow strict rules.

All of these and many more regulations will help protect beaches, nests, female sea turtles, their eggs and hatchlings from now on. I am proud to say that Defenders of Wildlife played a key role in making this happen. We worked on this regulation for many years; in fact we were the ones who proposed its creation back in 2002. It took a decade of lobbying before we got the Environment Ministry to develop it, and Defenders is one of only four non-governmental organizations credited with helping to make these new protections a reality. It took a long time to get these regulations adopted but now when sea turtles hit Mexico’s beaches to nest, they will find it a safer place than ever.

Swimming to Safety

Loggerhead Sea Turtle Hatchling (NPS)

Of the world’s seven species of sea turtles, six are found in U.S. waters or nest on U.S. beaches: green, hawksbill, Kemp’s ridley, leatherback, loggerhead and olive ridley. The seventh species, the flatback turtle, is found only in Australia. At one time, millions of sea turtles swam in our oceans — but now all sea turtle species in U.S. waters are listed as endangered or threatened under the Endangered Species Act (ESA). The protection of the ESA is actually a major reason that we still have sea turtles swimming our oceans today.

Sea turtles have been around for about 110 million years — since dinosaurs roamed the Earth. While sea turtles were exploited for centuries for their meat, demand escalated during European exploration of the Americas and the green turtle was nearly exterminated. In the 1950s and 1960s, expanding international markets for sea turtle shell, skin and other products were taking a toll on sea turtle populations.  By the 1970s many sea turtle populations had plummeted from direct harvest. During that decade all species occurring in the U.S. were listed on the Endangered Species Act and by 1981 all species were included on the Convention on International Trade in Endangered Species (CITES), which banned international commercial trade in sea turtles and their products.

Being listed on the ESA was a turning point for sea turtles. ESA listing makes it illegal to harm, harass or kill sea turtles, hatchlings or their eggs, or to import, sell, or transport sea turtles or their products. Once sea turtles were listed, federal agencies developed recovery plans and started programs cooperating with states for sea turtle conservation. They also created new regulations to reduce the number of turtles accidentally caught in fisheries and developed plans to acquire and protect important sea turtle habitat.

The listing also compelled the U.S. Fish and Wildlife Service and National Marine Fisheries Service to consult with other federal agencies on projects they fund, permit, or conduct to ensure that they do not cause harm to sea turtles or their habitat.  These new protections included important regulations requiring turtle excluder devices or TEDs in U.S. shrimp nets that were passed under the authority of the ESA to prevent the deaths of thousands of sea turtles each year. The United States also cooperates with other countries to protect sea turtles. For example, in 2004, Congress passed the Marine Turtle Conservation Act to provide funding for conserving sea turtles and their nesting habitat in other countries. The Act recognizes the global plight of sea turtles and the need for close cooperation among countries, and provides the U.S. Fish and Wildlife Service support for on-the-ground conservation initiatives to benefit sea turtles.

ESA listings are relevant at the state level as well as the federal and most states where sea turtles nest have now passed additional laws to protect turtles. In Florida, for instance, the Marine Turtle Protection Act gives state agencies the power to enforce regulations that protect turtles and their habitat. States coordinate extensive monitoring and research efforts on nesting beaches. Some local governments have also passed regulations to eliminate or control artificial beachfront lighting, which deters females from nesting and disorients hatchlings.

Even though the Endangered Species Act is a U.S. law, it has made a big difference to sea turtle recovery on a global scale. Sea turtles are highly migratory — over the course of their lives they will live not only off the U.S. coast but in waters of other countries. Because sea turtles rely upon different habitats during their lifetimes and migration, they are vulnerable on multiple fronts, and conservation efforts for turtle populations in one country may be undermined by activities in another. It is critical that all nations cooperate to ensure the survival of sea turtles.

Loggerhead Sea Turtle

In North America, sea turtles primarily nest from North Carolina through Florida and along the beaches of the northern Gulf of Mexico, with over 90% occurring in Florida which hosts a globally-important nesting population of loggerhead turtles. Numbers of nesting leatherback and green turtles have been steadily increasing in Florida. Considering that green turtles were on the brink of extinction in the late 20th century, the resurgence of this species in Florida is cause for celebration.

Because the ESA encourages habitat to be protected for listed species, Congress established the Archie Carr National Wildlife Refuge in 1989 to protect federally endangered and threatened sea turtles. The Refuge offers hope for saving one of the most important sea turtle nesting sites in the world along a 20.5-mile stretch of beach on Florida’s east central coast. It contains long stretches of quiet, undisturbed sandy beaches, with little or no artificial light, that are essential to the reproductive success and survival of sea turtles. The refuge also includes the most significant area for loggerhead sea turtle nesting in the Western Hemisphere, the most important nesting beach for green turtles in North America and a small but quickly growing rookery for leatherbacks.

While several sea turtle populations have improved since being listed on the ESA and CITES, serious threats remain.  Turtles are accidentally caught in commercial fishing operations, often drowned in nets or caught on lines intended for other types of marine life, or can accidentally eat or get caught up in plastic or other debris. The turtles’ coastal habitat is also in trouble – development is a constant threat to nesting grounds, as is construction of seawalls and artificial light pollution.  And as with so many species, a changing climate is causing swaths of the sea turtle habitat to change drastically, or even disappear.

That is why the protections provided by the ESA, along with the work we and many other organizations do to defend this important legislation, are as important today as they were when they were adopted 40 years ago. In the coming year, Defenders will build upon its work to protect sea turtles from death and injury both at sea and on U.S. and Mexican nesting beaches, continuing to focus on reducing the number of turtles that die accidentally in fisheries and expanding our work to protect Florida’s and Mexico’s important nesting beaches from harmful coastal development and disturbance.

Endangered loggerhead turtle

The Long Journey Home

Juan Carlos Cantu, Mexico Program Manager

An incredible animal with an incredible story, the Pacific loggerhead sea turtle will face many challenges throughout its life. From the day it is born, it enters the vast waters of the Pacific Ocean and travels thousands of lonely miles as it struggles to reach adulthood, return to the place it was born and continue the circle of life. Despite the perils of such a journey, the most severe threat these animals now face is humans.

Loggerhead Sea Turtle Hatchling (NPS)

Loggerhead Sea Turtle Hatchling (NPS)

The Northern Pacific loggerhead sea turtle nests on the coasts of Japan, where it can lay approximately 95 to 150 eggs. After 56 to 80 days, the nestlings hatch and enter the cold Japanese waters to start one of the most amazing journeys of any living species. Their goal is to cross the Pacific Ocean to arrive at the rich feeding grounds off the Pacific coast of Baja California Sur in Mexico. The origins of this migration are a mystery, but the reality is that these small loggerhead sea turtles must travel 7,500 miles of open sea to reach their destination. This is an immense body of water for the little turtles to swim, and the trip can take up to six years. By the time they arrive in Baja, those that survive are no longer small hatchlings, but fairly large juveniles. They spend the next 10 years in Mexican waters, where they feed mostly on crustaceans called pelagic red crabs in a relatively small area in front of the Bay of Ulloa.

Slow to grow and mature, even at 15 to 20 years of age, loggerheads are still considered subadults when they begin their journey back across the Pacific. They will roam the Northern Pacific until they reach their reproductive age, then swim back to the beaches in Japan where they were born and start a new cycle of nesting. The round trip takes decades to complete, and the adult sea turtles will never leave these waters to traverse the Pacific Ocean again.

Unfortunately, the number of nesting females in Japan has decreased by 90 percent in the past three generations, which qualifies this loggerhead population as critically endangered. The main culprit is “bycatch” — the unintentional capture of sea  turtles in fisheries.

In the waters off Japan, loggerhead sea turtles fall prey to massive nets, while in the open ocean the threat comes from the international longline fleet, which consists of fishing lines dozens of miles long, each with thousands of hanging hooks. Drift net fisheries (huge, miles-long nets that capture everything in their path) and gillnet fishers in the Pacific also have high bycatch of loggerheads. The National Marine Fisheries Service has noted that just 37 to 92 North Pacific loggerheads killed each year through bycatch would increase the species’ risk of extinction. In Mexico, these sea turtles are even more vulnerable to bycatch because they gather in such small areas to feed. Coastal fisheries in Baja, which mainly target shark and halibut, are capturing a staggering 1,000 loggerheads every year.

For years, teams of NGOs and scientists tried to convince fishermen to use alternative fishing gear and modify their fishing practices. Defenders of Wildlife helped this effort by producing materials like posters and even comic books with information on how to help sea turtles. Eventually these efforts started to pay off — fishermen were changing their fishing practices voluntarily, and bycatch was being reduced. Unfortunately, a recent seasonal ban on shark fishing prompted fishermen to start using their old methods on other species to increase their total catch, and as a result, bycatch has skyrocketed.

Bycatch alone is not illegal because it is not intentional. The problem here in Mexico is that the loggerheads’ feeding areas have little protection, and there are no regulations that mandate the use of alternative fishing gear or practices to reduce bycatch or in any way limit the number of sea turtles that can legally be caught as bycatch. For years, we worked to develop shark fishery regulations that include provisions to decrease sea turtle bycatch in Mexican waters, and in 2007, these were finally published in the official register. These regulations included a ban on drift nets and all surface nets, as well as mandatory use of circle hooks in surface longlines, which have been shown to be very successful in decreasing sea turtle bycatch and mortality. These efforts have helped, but since many Baja coastal fisheries use bottom-set longlines and gillnets, which invariably drown sea turtles, it has not been enough.

At the same time, Defenders joined an effort by local and international NGOs and research scientists to request that the Environment Ministry create a refuge area to protect loggerheads in their feeding grounds. For the past five years, environmental authorities have dragged their feet on this issue, with never-ending stakeholder meetings that resulted in no protected area, and no regulation of the different types of coastal fisheries that are negatively impacting the loggerhead population. This year, bycatch increased by 600 percent, making it the highest bycatch rate of loggerheads in the world.

We have denounced this unnecessary mass mortality, publicly demanding that government institutions, which are obliged by law to protect endangered species, take action immediately to put a stop to this loggerhead massacre. The response from the authorities was swift, promising to increase vigilance of fishery activities as well as confirming that a draft refuge area decree is in the works, but we haven’t seen anything yet.

On December 1st, a completely new administration took over, and we are hopeful that this may be the break loggerhead turtles need to finally get some real protection in place. We’ll keep you posted on what happens, and we will not stop until the North Pacific loggerhead population in Mexican waters has the protection it needs to survive.

On Florida Beaches, a Bumper Crop of Baby Turtles

Florida is in the midst of a baby boom, but not one you might expect.  There are 50 percent more sea turtle nests on Florida beaches this summer than in past years, a pleasant surprise to wildlife researchers.  The threatened loggerhead and endangered green and leatherback turtles are all species that nest on the Florida coast.

Sea Turtles, (c) William R. Curtsinger / National Geographic Stock

Newborn sea turtles like these have a long swim ahead of them. We can help them get the best possible start by turning off artificial lights at night and keeping away from their nests.

Scientists aren’t sure what caused the sudden spike in the nest count, though some of the turtles may have increased their food intake this year.  What we can be sure of, though, is that we need protections for sea turtles to ensure that we have more banner seasons like this one.

Turtle Excluder Devices, or TEDs, help prevent sea turtles from being caught in fishing nets.  Regulations requiring most shrimp nets to have TEDs have been in place since the 1990s, but exempted nets still capture over 28,000 sea turtles every year.  The National Marine Fisheries Service (NMFS) recently proposed to close the gap and extend the requirements to all shrimp nets, but wildlife opponents in Congress are moving to block this recovery effort.

Defenders is working hard to fight this opposition and make the oceans safer for the tiny hatchlings that will soon be heading out to sea.  Meanwhile, you can help sea turtles by reducing artificial lights at night if you live near nest beaches, since they can confuse and attract sea turtles trying to crawl back to the water.  Make sure to keep kids and pets away, too.  You can also help by picking up beach trash, which can attract raccoons and other predators.

Conservationists can feel hopeful that Florida nest numbers are up.  The true test, though, will be the number of turtles hatched on Florida beaches that return to lay their own eggs, many years from now.

Turtles and Salmon on the Chopping Block

US Capitol, FWSYesterday, wildlife opponents in the U.S. House of Representatives took two deadly swipes at some of America’s most important (and imperiled) animals.

In what has become a troubling tradition in recent years, several members offered amendments to an appropriations bill that undermine critical wildlife protections. This time, the insidious riders were added to the Commerce, Justice and Science funding bill for the next fiscal year.

The first provision, introduced by Rep. Jeff Landry (R-Louisiana.), would prevent the National Marine Fisheries Service (NMFS) from moving forward with a proposal to expand protections for sea turtles. Each year, some 28,000 threatened and endangered sea turtles are caught in shrimp fishing nets that are currently exempted from requirements to use turtle excluder devices, or TEDs, which allow turtles escape from the nets.

Sea Turtle, (c) Brian J. Skerry / National Geographic StockExisting regulations have required most shrimp boats to use TEDs since the 1990s, but a loophole in current law exempts some types of trawl fishing from the requirement. In 2010 and 2011, unprecedented numbers of dead sea turtles washed ashore, prompting Defenders and other conservation groups to call for this loophole to be closed.  NMFS agreed and issued a proposed rule to do just that following settlement of litigation (see Defenders press release).  Now, Rep. Landry’s amendment could short-circuit the public’s ability to weigh in on expansion of these protections.

The other appropriations rider, introduced by Rep. Jeff Denham (R-California), would effectively block the recovery of salmon populations in California’s San Joaquin River. Friant Dam, completed in the 1940s, diverted nearly 95 percent of the San Joaquin’s water away from the river for agriculture, wreaking havoc on salmon and putting many commercial fisherman out of business. After years of litigation and negotiations, farmers and fisherman finally reached a settlement agreement to restore salmon to the San Joaquin. However, Denham’s amendment would scuttle restoration efforts by denying much-needed funding. Notably, all parties to the settlement agreement continue to support salmon restoration and oppose legislation that modifies its requirements. Clearly, Rep Denham is catering to outside parties and playing politics with our endangered species.

Defenders will be watching the appropriations process very closely over the coming weeks and months and doing everything we can to make sure these provisions are dropped from the final bill. We’ll need your help to hold members of Congress accountable for maintaining vital funding for protecting all our imperiled wildlife.

Stay tuned…

New Rules Will Protect Cape Hatteras Wildlife

Piping plover with chicks

Responsible beach management will allow imperiled wildlife like the piping plover to continue down the path to recovery.

BREAKING: The National Park Service (NPS) today announced new rules to manage off-road vehicle traffic on beaches so nesting and baby sea turtles and birds as well as pedestrians are protected in Cape Hatteras National Seashore, according to conservation groups.

In 2007, the groups—Audubon North Carolina, Defenders of Wildlife and Southern Environmental Law Center— turned to the courts for help in getting the NPS to  implement long overdue safeguards for pedestrians and beach-nesting wildlife on park beaches overrun by off-road vehicles.

“The park service’s rules are a compromise that provides protections for both pedestrians and wildlife while still allowing responsible beach driving,” said Julie Youngman, senior attorney, Southern Environmental Law Center.

The long-awaited rules are the final step in a process agreed to by all parties concerned about beach driving in the national seashore. During an interim management period prior to today’s rulemaking, rare bird and sea turtle populations showed signs of recovery, park visitation held steady or increased annually, and tourism remained strong in Dare County, NC, where much of the seashore is located, despite a recession.

“With both the number of hatchlings and visitors to the beach climbing, the success of responsible beach management is clear,” said Jason Rylander, senior attorney for Defenders of Wildlife. “The new rules will ensure that Cape Hatteras continues to provide enjoyment to beach users while protecting the unique wildlife that call the seashore home.”

Tourism flourished in Dare County during the period when interim protections were in place.  Rental occupancy receipts in Dare County increased by millions over the previous decade as recorded by the Outer Banks Visitors Bureau. Park visitation and gross occupancy inDareCountyduring peak breeding and nesting season under interim management held steady or increased compared to the three preceding years. According to a state report on tourism for 2009-2010, Dare County experienced an 8.8 percent growth in tourism—making it among the top growth counties in the state during a recession.  The county’s strong tourism industry employed 11,260 people with $172 million in payroll and generated $44.55 million in tax receipts for the state and $39.78 million in local tax receipts.

After three years of temporary protections, a record-breaking 153 sea turtle nests were recorded at Cape Hatteras.

As a unit of the National Park System, Cape Hatteras National Seashore has been required under federal law since 1972 to establish guidelines that minimize harm from the use of off-road vehicles to the natural resources of the seashore in accordance with the best available science for present and future generations. The new rules bring the NPS into compliance with that requirement.

The park service’s rules allow ORV use on the majority of the seashore. Twenty-eight of the seashore’s 67 miles are set aside as year-round ORV routes, with only 26 miles designated as year-round vehicle-free areas for pedestrians, families, and wildlife. The remaining 13 miles of seashore are seasonally open to ORVs.  The plan also proposes new parking facilities, ORV ramps, and water shuttles to increase visitor access to beaches.

“Under the reasonable, science-based management of the past few years, beach-nesting birds and sea turtles are rebounding at Cape Hatteras National Seashore and visitors continue to flock to this national treasure,” said Heather Starck, executive director of Audubon North Carolina. “The new rules appear to give the National Park Service the guidance to protect and manage the natural resources while allowing for responsible ORV use.”

With temporary beach driving rules implemented in April 2008, beach-nesting birds and sea turtles within the national seashore showed signs of recovery after reaching alarming lows under unmanaged beach driving. Only 44 sea turtle nests were recorded in 2004, but a record-breaking 153 sea turtle nests were recorded in 2010 and 147 sea turtle nests were recorded in 2011. No piping plover chicks survived to fledge (learn to fly) in 2002 and 2004, but 15 chicks fledged in 2010 and ten fledged in 2011.
