Origin

Yilan Shuang-lian-Pi is a barrier lake surrounded by mountains, where there is a rare wild animal and plant habitat. According to reports, Shuang-lian-Pi comprises 80 families and 202 species of plants and of them, there are such rare plants as Salix kusanoi, Philydrum lanuginosum, Trapa bispinosa, Utricularia exoleta, Limnophila, Brasenia schreberi, Eleocharis ochrostachys, Rhynchospora malasica, and so on. The aquatic plants here take one-third species of Taiwan. It is the top wetland of the most abundant aquatic plants. Determined by ratio of species per area, Shuang-lian-pi is one of the rarest wetlands in the world. If can be regarded as “National Wetland,” there are 56 species of aquatic insects over the wildlife habitat. And it is the habitat for some protected animals according to Wildlife Conservation Act such as Emerald green tree frogs, Taipei green tree frogs, and yellow turtles. Dr. Chen Tien-His at National Museum of Marine Science & Technology has investigated that yellow turtles have given a steady amount of breeding in Shuang-lian-pi, which is the yellow turtles’ secondly significant breeding place. It is a rare place in Taiwan: the water region is only of 17 ha but it raises an ecosystem of biodiversity. When the other lakes at the low latitude have been destroyed swiftly, Shuang-lian-pi has become a valuable habitat.

Heavy fogs often cover the wetland. Weeds, reflections in the water, and sounds of nature paint Shuang-lian-pi with hues of isolated beauty. This gorgeous environment naturally breeds an ecosystem of biodiversity. And it attracts plenty of filmmakers to work in such exquisite scenery, for instance, the movie, “Scarecrow.” There is one more special thing in Shuang-lian-pi. There is one more special thing in Shuanglianpi. Above the lake is piled up by submerged aquatic plants, forming a grass carpet having a size of a football field. The green carpet moves around in different seasons. Especially in the typhoon season, it moves so considerably that it is called a wonderful view in the nature. The twisted roots and decayed soil is 3 Tai-chis thick (1 tai-chi equal to 0.30303 meter.) Except for another green carpet in Sun Moon Lake, the other one in Shuanglianpi is a scenic wonder in Taiwan.

To protect the valuable wetland ecosystem in Shuang-lian-pi, the Council of Agriculture, Executive Yuan announced Shuanglianpi as a major wildlife habitat according to Wildlife Conservation Act, on October 23, 2003.

Location

Located in the northeastern part of Taiwan, Shuang-lian-pi is a natural barrier lake surrounded by mountains. In the valleys of Husi Village in Yuanshan Township, Yilan County, Shuanglianpi, at the latitude of 470 meters, is 3 kilometers from the Fushan Botanical Garden. Occupying an area of 18 hectares, Shuanglianpi consists of large and small lakes, called the upper and lower wetlands by the local people. The name “Shuanglianpi” is derived from the fact that these two wetlands are interconnected, “shuang” means both, “lian” means connected and “pi” means wetland). But now the lower wetland has been deposited as a mire land, the upper wetland still remains the primaery water resource.

An Introduction

Shuang-lian-pi literally means two connected lakes. The big, senior lake, 500 meters in length and 300 meters in width, grows grass by its skirts and thrives some rows of bamboo intersected by the lake. The small, junior lake, 200 meters in length and 100 meters in width, is gradually deposited by mountain soils as a mire land with grass. The area in total is 18 ha. Grass is densely clothed around the lake. When autumn and winter meet, white awns thrive. And the beauty is beyond description. Between the two wetlands, there are two floated islets covered by aquatic plants. Whenever the seasons change their positions, both of the islets will float away. It is said that it becomes the unique scenery in Shuanglianpi.

The lake water of Shuanglianpi comes from the underground springs and mountainous streams. Because of its purity, the fish breed is abundant. It makes this place the best habitat for the migratory birds in winter. By the wetland bank are inhabited by several farming families. At the entry to Shuang-lian-pi, a large scale of Japanese cedars planatation is put in order which opens up trails in the woods. Tourists can trace along the wood trails by the lake and can take forest baths while enjoying the lake scenery.

This area is one of the rare wetlands at the low latitude. According to the reports in the academic circle, there are 80 families and 202 species of plants.

The aquatic plants here take the one-third species of Taiwan. It is the top wetland of the most abundant aquatic plants.
