The Yushan National Park Headquarters called Wednesday on those who have not done so to vote for Yushan, or Jade Mountain, as one of the world's natural wonders, as the second stage of global online voting entered its final month. The 3,952-meter mountain, the highest in Northeast Asia, has so far maintained the top position in the 'mountain, volcanoes' category in the second round of voting for the world's new seven natural wonders organized by the Swiss-based New7Wonders Foundation, which is scheduled to end July 7. According to the park headquarters, continued support for Yushan from the public is essential if it is to continue the leading position amid intense competition from other nominees. Over the past month, many newcomers have entered the top five in the 'mountain, volcanoes' ranking, squeezing Mount Everest and Mount Fuji off the list, park officials noted. The five recent entries are Greece's Mount Olympus, which climbed from sixth to second; Italy's Mount Vesuvius, which shot up from 13th to third; Azerbaijan's Mud Volcanoes, which soared from 21st to fourth; and South Africa's Table Mountain, which rose from 27th to fifth. To drum up support for Yushan, the park headquarters is holding various events in the coming month to encourage the public to take part in the voting being held at www.new7wonders.com. They include an exhibition and performance scheduled for June 14 at Taipei's Chiang Kai-shek Memorial Hall, and a cycle race set for June 20 in Tataka, the highest point of the New Central Cross-Island Highway. From June 22 to July 6, the seven Yushan publicity ambassadors -- selected in April through an online vote -- will make a cycling tour around Taiwan. Yushan, located on the boundaries of Chiayi, Nantou and Kaohsiung counties, is known for its diverse wildlife and ecology. It is the only natural attraction from Taiwan to make the list of contenders in any category. As of June 9, Africa's Kalahari Desert had taken the top position in the 'landscape, ice formations' category; Ecuador's Galapagos Islands in the 'islands' category; Serbia's Djavolja Varos in the 'caves, rock formations, valleys' category; the Philippines's Puerto Princesa Subterranean River in the 'forest, national parks, nature reserves' category; South America's Lake Titicaca in the 'lakes, rivers, waterfalls' category; and Vietnam's Ha Long Bay in the 'seascape' category. The top 11 sites chosen in each of the seven categories by July 7 will then be reviewed by a panel of experts headed by Federico Mayor Zaragoza, former UNESCO director-general, who will select three nominees in each category. The 21 nominees will be put to a final round of worldwide online voting in 2010 and 2011 to select the top seven natural wonders.
