Oceana, along with the Center for Biological Diversity and the Turtle Island Restoration Network, announced last week that they intend to sue the federal government over its failure to designate critical habitat areas for loggerhead sea turtles in the Atlantic and Pacific Oceans – an action required under the Endangered Species Act but that has not yet been done.
Loggerhead sea turtles currently face threats from commercial fisheries, habitat destruction, and climate change along our coasts and throughout the Gulf of Mexico. Unfortunately population recovery efforts are slow, as turtles are long-lived animals that typically don’t reach sexual maturity until 20-35 years of age.
The designation of critical habitat is expected to help restore plummeting population numbers, as species with identified critical habitat are more than twice as likely to show recovery in overall numbers. The designation of critical habitat will likely protect nesting and foraging grounds that are important to the survival and recovery of these turtles.
In order to designate critical habitat, the federal government must first identify areas that are essential to the survival and recovery of the species. More than 90 percent of the U.S. Atlantic nesting population of loggerheads nests on U.S. beaches along the eastern coast of Florida. Critical habitat designation is vital to the survival and recovery of threatened and endangered species. Every day the government delays means more turtles caught in nets and more habitat areas destroyed without consideration of the impacts on the population.
It’s no secret that the health of our oceans is under extreme threat.
With dangers like overfishing, climate change and ocean acidification, keeping our oceans healthy is a complex problem that has proved difficult to address.
Scientists and policymakers now have a little help, however, with the recent creation of the Ocean Health Index. Developed by a multidisciplinary team of researchers, the index provides an overall score for global ocean health, using 10 different social, economic and ecological criteria such as water quality, habitat, livelihoods, and coastal protection.
The research findings, published in the journal Nature last week, gave our oceans a collective score of 60 out of a possible 100 points. Scores were calculated for 133 different regions located around the world, with marine waters from some countries ranking as low as 36 while others as high as 86. The United States scored only a little higher than the global average, with 63 points. Disturbingly, only 5 percent of these regions scored above 70 points.
