碩士 / 國立臺灣師範大學 / 地理研究所 / 91 / The biodiversity in Taiwan is in evidence since it is located on the border of the plates on earth. Besides a great deal of residents, many traveling species make their temporarily halts on the island, such as migratory birds. However, half bird species in Taiwan are travelers and the waterbirds are possessed of great amount that many of them roost along or near the coastal area.
36 families and 123 species of birds were found in four sample areas during April 2001 to March 2002, which included 73 waterbird-species and 50 landbird-species. Due to the high proportion of traveling birds in the sample areas, the amount of bird species varied seasonally that it demonstrates higher in spring/fall and represents sparse in summer. Furthermore, a large number winter visitors, the dominant species, bring about the maximum amount of birds in winter. As the environmental condition is different from each other among sample areas, the dominant species in each area has its uniqueness which is just like the dunlins in the tidal flats, the pacific golden plovers in dry farms, the green-wing teals in rice field A, the sparrows and wood sandpipers in rice field B, and the tufted ducks in pond areas.
The extensive wetlands on the west coast of Taiwan provided habitats for many birds whether visitors or residents during early period. While the government began to strive to pile up some man-made works along the coast two decades ago, both the amount of birds and bird species declines significantly these days. In the mean time, the enhanced conservation issues recently force the government to protect coasts, yet there are still lots of unofficial protected areas under polluted and destroyed now.
The thesis discusses the biodiversity of birds in unprotected habitats which is affected by humans, and devotes to keep our balance between the economic benefits and environmental ecology.
