Yilan Branch

Branch Office Overview

The jurisdiction of the Yilan Branch extends from coastal mangrove forests to alpine areas at 3,600 meters above sea level, covering climatic zones from subtropical to temperate and subalpine. This diversity has fostered abundant forest resources. According to the Fourth National Forest Resource Survey, 75% of the forest area under its management is natural forest, while 25% is plantation. Timber stock includes 10,294,886 cubic meters of conifers and 28,252,398 cubic meters of broadleaf trees. Plantation forests account for 12,317,402 cubic meters and represent substantial economic value. Coniferous species such as Taiwan red cypress, Taiwan cypress, and Japanese cedar make up approximately 52% of the total timber volume, followed by other economically valuable broadleaf species.

Among the various forest types, the cypress forests of Qilan and Taipingshan are particularly renowned. These ancient giants, many over one thousand years old, are regarded as a shared national treasure. The beech forests in the Tongshan area represent the southernmost known distribution of the genus worldwide and are the largest pure beech forest discovered in Taiwan. Taiwan Cow-tail Fir has highly restricted populations at the northern and southern ends of the island. Consequently, habitats of Taiwan Cow-tail Fir along the Gupoliao and Jingualiao streams in Pinglin have long been designated as nature reserves under the Cultural Heritage Preservation Act. Additionally, the mangroves at the Tamsui River estuary form the northernmost and largest pure stand of Kandelia candel in Taiwan. Beyond timber and plant resources, the forests support over 30 species of mammals, more than 200 species of birds, and over 70 species of amphibians and reptiles. Among these are rare and endangered species listed under the Act on Wildlife Conservation. These forests provide critical habitats that sustain the survival of such species while maintaining the region's rich and diverse ecological environment.
