ek het die ook raakgeloop
dis blykbaar georganiseer deur die regering
dan vra ek verskoning as ek nie die hele verhaal aan die begin geken het niehttp://www.save-a-turtle.org/?p=486
I’m sure many of you have received the e-mail showing pictures of a turtle egg harvest in Costa Rica and calling for criticism of the Costa Rican government. As usual, the truth isn’t quite as black and white as that. Indigenous peoples in many places have been harvesting turtle eggs for years & years, and it’s a cultural and economic way of life for them. These are most likely pictures of the legal harvest allowed at Ostional Wildlife Refuge in Costa Rica. Although the locals harvest about 3 million eggs a year, about 27 million are left in place to hatch. Locals are only allowed to collect during the first 36 hours of a nesting arribada, and most of those nests would have been destroyed anyway by subsequent females digging nests on the same beach. (Because all species of ridley turtles nest in huge groups over a period of just a few days, this destruction by other nesting females is considered to be the biggest threat to olive ridley populations, topping all other human-induced forms of mortality. 70-80% of all ridley nests laid are destroyed by subsequent nesting females.). This nest destruction is a normal part of the ridley life cycle, and predators such as coyotes have co-evolved and will show up in large numbers a day or so before arribadas so they can gorge on the exposed eggs. Initial studies have shown that the legal harvest in Ostional may actually increase overall hatching success by as much as 20% for several reasons:
1) Locals are protecting the remaining nests from poaching (to guarantee future harvests), keep the beaches clean of trash, and usher hatchlings into the water.
2) If dug-up and broken eggs were left on the beach to rot, they can cause bacterial infections that spread to incubating eggs and can destroy whole clutches.
3) Because it’s a government-regulated harvest, the Costa Rican government sets the cost of turtle eggs country-wide (making them comparable to the cost of chicken eggs). This discourages poaching on other beaches because the economic gain is not worth the risk of punishment if caught poaching.
Costa Rica recognizes its incredible biodiversity as an economic boon, and has actually done a very good job of protecting sea turtles and other plant and animal species. Tortuguero National Park, one of their most important nesting grounds has been protected and locals are now earning a living through eco-tourism and by protecting the nesting areas from poachers. Overall, Costa Rica has set aside an astonishing 27.27% of the country as National Parks, forest reserves, buffers zones, wildlife refuges, and Indian reserves. That’s a larger percentage of protected lands than any other country in the world.
The Costa Rican government has hit upon a solution that works for it and actually improves overall hatching success rates for these turtles, and all it takes is a few minutes of research to uncover the truth.
