Here today, gone tomorrow
Taiwan boasts 4,100 indigenous plant species, at least 1,069 of which are endemic-unique to Taiwan-but many are nearing extinction in the wild. For instance, there are less than 100 individual Gentiana tentyoensis plants in the mountains of Hualien, and fewer than 50 of the Taipei-area fern Pteris wulaiensis are left. "When there are less than 1,000 individuals remaining of a species, it's obvious that they're facing the danger of extinction," says Li, stressing that there are many species out there that have been seen but not yet documented, and whether they still exist remains a mystery.
Taiwan has a Wildlife Conservation Act, but this act ignores the most basic and important part of the ecosystem: plants. Besides the impracticality of preventing people from going out and picking plants, there is the more disquieting problem of natural disasters permanently destroying habitat.
In August 2008, collection manager Wang Yifu was walking through the slopes of Beidawushan at an elevation of 700-800 meters, and accidentally stumbled over a never-before-seen orchid that reflected sunlight with fiery-red colors. After examination by experts from Taiwan and abroad, it was determined that he had discovered a new species. It was dubbed Cheirostylis rubrifolius.
But prior to its publication in November 2009, the habitat of Cheirostylis rubrifolius was destroyed in a serious landslide caused by August's Typhoon Morakot. Besides the two specimens gathered for preservation, all known remaining individuals, numbering less than 20, disappeared, and it is feared that they may be completely extinct.
"Sometimes when a newly discovered species is awaiting publication, a natural disaster can completely wipe it out," says Li. But Cheirostylis rubrifolius wasn't the only victim of Typhoon Morakot's blow against Taiwan's ecosystem: the fate of another species, the fern Adiantum meishanianum, hangs in the balance.
Amateur fern aficionado Wang Bizhao discovered Adiantum meishanianum in Meishan Village in Kaohsiung County's Taoyuan Township in 1983, but it was not until March 2008 that it was confirmed to be a new species in a paper by Taiwan Forestry Research Institute researcher Chiou Wen-liang.
Ferns have spores, which float everywhere with the winds and are thus able to propagate widely. But since the discovery of Adiantum meishanianum over 20 years ago, it has never been recorded in any other location, living in a tiny habitat range of 200 square meters. Conservation center collection manager Chen Chun-ming postulates that this may be related to its tendency not to reproduce until the ends of its leaves touch the ground.
Adiantum meishanianum grows only near a suspension bridge in Meishan Village near the South Cross-Island Highway. Though the bridge survived the flooding caused by the typhoon, the state of the adjacent river habitat remains unclear because the road was completely cut off and nobody has been able to reach the area since. This is distressing, and it makes the nine individual plants kept at the conservation center that much more precious.
Wang Yifu mentions that no scholar had laid eyes on Taiwan's endemic orchid Liparis amabilis since it was described by the Japanese botanist Noriaki Fukuyama in 1938. But in 2008, 70 years after its "disappearance," a man surnamed Lin discovered a plant in the mountains of northern Taiwan and sent it to the conservation center. When it bloomed in the greenhouse that March, it turned out to be the legendary Liparis amabilis. The center's personnel excitedly recorded everything they could about it, making it one of Taiwan's most precious documents on an orchid.
