Key words：Chiroptera, echolocation, latitude distribution, species components Bats play a vital role in ecology, including, pests control, seeds spreading and pollen. Meanwhile, more studies suggest that bats supply highly economic ecology services. Also, bats are nature reservoirs for virus and disease. To realizing bats population and distribution is necessary for basic ecologic research, bats conservation, monitoring biological indicators and epidemiology and conservation medicine for wildlife. There are 6 families and 36 species in Taiwan. Taroko national park cover wide range area from the highest Na-Hu mountain 3,742m to the lowest to near the sea surface. In this varity ecology typies and completcate geology and climate conditions. We expected that there are high diversity of bat species. In previous studies, 10 species were roughly recorded, on the other hand, this study focus on bats species detail invergetion. Aims of this study include: List of bat in Taroko national park, Contribution of database for each bat detail and its echolocation and Distribution of bats in Taroko national park. This study is in Taroko national park. It was divided into three areas and four seasons- low latitudes (60-1,100m), middle latitudes (1,100-2,200m), and high latitudes (2,200m above). We used harp tarps, echolocation dectiors, caves investgations and field interview to collecting the data. There are 5 families, 15 genus, 24 speceis and 105 indiviuals recorded in this study. Addionlly, with previous studies there are 5 families, 15 genus, and 25 speceis in the national park. For the highest recaptured rate, in high latitude, Submyotodon latirostris (n=2) takes the first place and Murina puta accounts high amount in the low latitude. Overall, the highest bats diversity in season three (July-Semtember) and in middle and low lititudes. Thousands of Rhinolophus monoceros were found in season two in east side of Ni-An bridge in cave one for reproduction and fed babies. In season three only sub-adult of Rhinolophus monocero left in the cave. However, a little numbers of them in the season four.
