TOO MUCH TURTLE TORQUE? Text and pictures by Robert Baldwin |
Turtles are a topical subject for conversation in the Sultanate of Oman. In fact, murmurs of their abundance here are already beginning to echo around the world, prompting a well-deserved claim to international distinction. Five, out of a recognized seven species of marine turtles are found in the seas of the Arabian Peninsula . Four of these nest on beaches along the vast and varied coastline of Oman and between them they share records of global significance, some worthy of esteemed enunciation, others indicating cause for concern.
Green Light of Fame While turtle watchers come and go, the eggs remain buried in the sand for approximately 55 days before hatching. An eruption of sand is followed by the appearance of energetic hatchling turtles, small enough to rest easily in the palm of a hand - if they would keep still for long enough. The first to emerge are those who tunnel their way to the surface, whilst the layers below successively push the excavated sand beneath them, rising together, as if on an escalator, towards the surface. Then begins an impulsive race for the sea and a life-long struggle for survival. Even before reaching the pounding waves of a vast and threatening ocean, predators such as wolves, foxes, ratels, seagulls and crabs, see to the demise of most of the hatchlings. As little as two or three in every ten thousand have been estimated to survive to adulthood. In spite of the odds, green turtles, have been nesting on the beaches of Ra's al Hadd, for centuries. The egg-laying effort has therefore been worthwhile and has succeeded in maintaining a large population. Recognizing that the green turtles here constitute probably the largest nesting population in the Indian Ocean (an estimated 12-13000), the Ministry of Regional Municipalities and Environment is playing a vital role in laying the foundation for future generations of turtles. Turtle rangers patrol the beaches in an attempt to ensure undisturbed nesting, whilst data they collect is fed into the management planning process in Muscat. From this will emerge a conservation program, which will be warmly greeted by many and contribute further to the green turtles' increasing fame.
Talking of Turtles... Nesting aside, from shallow intertidal shelves to coral reefs and open ocean, turtle feeding grounds in Oman are both rich and extensive. Productive environments supporting favoured foods of the green turtle, including beds of seagrass, shallow lawns of algal turf and copious forests of seasonal kelp, have yielded as many as 100 feeding turtles per kilometre of coast. Whether or not these turtles are part of the same population as those that nest in Oman, is not known. Are they perhaps an exclusive Oman population of feeding and breeding turtles? Are they part of migrant populations passing through the Sultanate, stopping to feed wherever food is abundant? Or are they a mixture of resident and migrant turtles? Tagging studies are underway in an attempt to answer such questions. Already, turtles tagged on Masirah Island and at Ra's al Hadd have reached the shores of the United Arab Emirates, Saudi Arabia, Yemen, Ethiopia, Somalia and Pakistan. Conservation of turtles, that know no international boundaries, is a complicated task and is compounded further by sensitive local issues.
A Healthy Harvest?
Turtle Torque The meaning of that final glance from turtle to human, is perhaps captured by the fisherman, who simply remarked that, a turtle which has swum the oceans since a time before the time of his ancestors, but has no voice of her own, knows that action speaks louder than words. |
