In May 2009 scientists from the Wildlife Conservation Society reported in the Journal of Biological Conservation that Gabon is home to the largest nesting population of leatherback sea turtles in the world. They estimated that between 15,000 and 41,000 female turtles use Gabon’s beaches for nesting.
Four years later, in 2013, many of the same scientists published a new paper in the same journal, that reported approximately 17 percent of female turtles are blocked from nesting by stray logs that have washed up from the timber industry.
When I was in Gabon in 2012 I spent 2 weeks in Pongara National Park and saw firsthand how dangerous these logs were to female leatherbacks returning to the coast. I also noticed that the logs stopped the turtles from nesting farther up the beach, which exposed their nests to the tide and wave action. It is hard to believe something as simple as logs washing up on a beach could have such a detrimental effect on one of Earth’s most ancient and majestic creatures. To give you a better picture of how it happens, here are some photos of leatherbacks nesting on the beaches among the giant logs in November 2012. Photos.
