Major Habitat Type

Tropical and subtropical coastal rivers

Drainages flowing into

Philippine Sea

Main rivers to other water bodies

Lanyang and Peinan rivers



This ecoregion includes the basins on the island of Taiwan that drain east of the Chungyang Range into the Philippine Sea. It extends from the southernmost extremity of the island (Eluanbi) to Wushibi (the cape about 25 km SSE of Yilan) in the north. The ecoregion also includes the offshore islands of Lü Tao (Green Island) and Lan Yü (Orchid Island).

Terrestrial habitats

The terrestrial ecoregions include the Taiwan subtropical evergreen forests [IM0172] and South Taiwan monsoon rain forests [IM0171] at the southern end of the island (Wikramanayake et al. 2002).

Description of endemic fishes

This ecoregion includes only a handful of endemics, such as the species Rhinogobius delicates.

Justification for delineation

For Southeast Asia, delineations were determined using a bottom-up approach that employed both published and unpublished field data and expert assessment (Abell et al. 2008). The ecoregion corresponds to regions V and VI of Chen and Fang (1999).
