Loggerhead Hotspots Revealed

Thursday, February 23rd, 2012

Loggerhead sea turtles are apparently good at keeping secrets. Their ability to navigate and orient the ocean, while returning to their natal beaches long remained a mystery. Like many species, their juvenile years became known as the “lost years” as scientists struggled to determine where they went. Now recent research from published in Biological Conservation has revealed two previously undiscovered feeding hot spots in the Gulf of Mexico.

Sea turtles may have advanced skills in avoiding detection in the ocean, but the satellite tags that several females were fitted with gave up their secret. Many of the turtles headed for a foraging site off Florida’s Southwest Coast, but several also visited grounds near the northern tip of the Yucatan Peninsula. It is not known what is so attractive about these areas, but knowing that they are important to the turtles could have favorable results, especially in an area with declining loggerhead numbers.

This research marks a new direction in sea turtle conservation. Previous efforts to protect and manage populations focused primarily on their nesting sites. Since this is where turtles spend but the smallest minority of their life, it may not be the most effective strategy. Having seen a turtle lumber across the sand, you are instantly aware that this is not the habitat their long flippers were suited for. Looking at other aspects of their life histories could result in more robust policies and strategies to protect the turtles.

De-listing the Hawaiian Green Turtle

Friday, February 17th, 2012

Tuesday marked an interesting day in sea turtle conservation. The Association of Hawaiian Civic Clubs (AOHCC) filed a petition with the federal government to classify the green turtles found around Hawaii as a distinct population segment. To do so, however, the Hawaiian green turtle would need to be removed from the Endangered Species Act.

Proponents of the petition have some scientific support for their cause. Honu, as the Hawaiian green turtle is locally known, have strong nesting success. Since the 1970s, the nesting population has been increasing an average of 5.7% each year. These green sea turtles nest in the Hawaiian Islands, most within the Papahānaumokuākea Marine National Monument (an area the size of California). Adults also seem to remain in the area of the volcanic island chain.

Sea turtles in general are a highly migratory species, traveling through many different waters. For many years their juvenile life remained a mystery. They were seen crawling from a nest, then seemingly vanished, only to return years later as mature adults. Green turtles are also extremely slow in maturing, sometimes not reaching maturity until 35-40 years of age. As a species, the green sea turtle is threatened throughout its range, with the exception of Florida and Mexico’s Pacific Coast – where they are endangered.

The delisting of the honu would not leave it unprotected. Management would transfer to Hawaii. AOHCC Preseident Soulee Stroud has said, “This would be wonderful to bring the management of this important cultural animal back to the people of Hawaii.” Since the honu has cultural and religious significance in Hawaii, there is no doubt that they would work hard to protect them, but could this open a dangerous precedent? Should a migratory species be broken into distinct population segments?

Come Change the World in Costa Rica!

Monday, February 6th, 2012

At Sea Turtle Camp, we’ve always been inspired by the change that students can create. Over the years we’ve watched students return home carrying a conservation message, and we’ve seen their grassroots campaigns flourish in their own community. This is why we are proud to have committed to a sea turtle cause in Costa Rica.

Parismina is a small village of 400-450 people located along the Caribbean Sea. It has long been isolated from the mainland by rivers and the ocean, and is accessible only by boat or plane. The people have long been supported by the ocean by fishing and, in the past, the sale of sea turtle eggs. However, over a decade ago the young people of Parismina banded together to literally create a sea change.

The students reached out to the Coast Guard to receive training on nest patrols and relocations. They then began to patrol the beaches nightly, from February with the start of the leatherback season through the fall with the mass nestings of the greens. They found more value in the beauty of a live sea turtle than in the profit of a stolen egg, and in doing so inspired a whole town.

In a town where everybody knows one another, the students already could identify the few individuals that were poaching the sea turtles. They were parents of friends or people that they saw in school or church. They felt that they could convince them to change their practices if they showed him the worth of protecting the leatherbacks, greens, and hawksbills that come to the area. Usually, all it took was one night out on the beach learning the importance of the nesting females to the entire village.

The initial collaboration of teenagers and the Coast Guard has grown into the community-based, non-profit conservation group known as Save the Turtles of Parismina. And as their organization has expanded through the community, so have their successes. Poaching has decreased by almost two-thirds and an astonishing 10,000 neonates are saved each year. As Save the Turtles of Parismina has grown they have continued their support of the community, and now support approximately one-third of the village.

While the work involves long nights, patrolling stretches of beaches by moonlight in small groups, the value of protecting the turtles is priceless. Once you’ve seen the first mother cresting in off the surf and pulling herself across the volcanic black sand, we’re sure you’ll agree.
