Center for Biological Diversity: Iconic Turtles Disappearing From Atlantic, Gulf Coasts
Excerpt from this press release from the Center for Biological Diversity:
The Center for Biological Diversity and 20 partner organizationsĀ petitionedĀ NOAA Fisheries today to protect diamondback terrapins as endangered under the Endangered Species Act. Aquatic turtles who live primarily in coastal marshes and estuaries from Massachusetts to Texas, these animals have declined by 75% across most of their range in the past 50 years.
āTens of thousands of terrapins are drowning in crab traps each year. Without the lifeline of Endangered Species Act protection, theyāll sink into extinction,ā said Will Harlan, a senior scientist at the Center for Biological Diversity.
In many locations along the Atlantic and Gulf coasts, terrapin populations have been wiped out completely.
Drowning in crab traps is a leading cause of death. These traps are submerged cages with funneled entrances that catch both crabs and air-breathing terrapins. Around 3 million crab traps are deployed each year by recreational and commercial crabbers, which kill tens of thousands of diamondback terrapins annually.
In addition, between 25% and 50% of all crab traps are lost or abandoned annually in coastal waters. These derelict cages ā called ghost traps ā kill tens of thousandsĀ moreĀ terrapins every year. Researchers estimate 60,000 to 80,000 terrapins are killed in active and abandoned crab traps each year.
Yet simple, proven solutions exist that could save terrapins. Bycatch reduction devices installed on crab traps have no negative effects on crab harvests, but they reduce diamondback terrapin deaths by 94%.
Terrapins are also threatened by habitat loss from sea-level rise and development. Theyāve already lost half of their original wetlands and are expected to lose up to 60% of their coastal marsh habitat by the end of the century.
As these animals travel farther in search of habitat, thousands of egg-bearing females are killed along roads each year. Increasing pollution, poaching, predators, boat strikes and climate change also threaten them.
