Situated in the warm temperate to subtropical forest belt of Nanmu, Ficus and Castanopsis, natural forests and plantations each account for about half of the forest. The plantations include Japanese Cedar, Taiwania, Taiwanese Incense-Cedar, Taiwanese Spruce and a small plot of Taiwanese Yellow Cypress. Of these, Green Japanese Cedar and Taiwania make up a forest of trees as magnificent as the sea. Natural broad-leaf trees dominate the forest. In particular, Stout Camphor and Red Bark Slugwood from the Lauraceae and Fagaceae varieties are common. The tree varieties on the ridge are mostly Taiwanese Azalea, Chinese Guger Tree and Taiwanese Apple, while Cherry Blossom and Green Maple are planted along the trails and in the more spacious areas. Red flowers in spring and red leaves in autumn add more colors to the green forest. Visitors may sight as many as six types of Begonia along the trail during spring and summer. Tengjhih has the most Begonia in all of Taiwan.The “Tengjhih Begonia” named after the area is especially precious!
This area is full of wild animals, such as mammals (Red-bellied Squirrels, White-faced Flying Squirrels and Formosan Rock Monkeys) and more than 56 varieties of bird. Among the many songbirds, the Yellow Tit is the most notable bird and is easy to sight in this area. Every spring and summer, the nocturnal and migratory Large Hawk Cuckoo comes through and the Spotted Scoops Owl sings rhythmic songs, making Tengzhi a place that never sleeps! Birds are not the only species tha sing here. There are also 5 species of cicada including the Formosan Giant Cicada. In addition, there are 206 kinds of butterflies, of which the beautiful Papillion family is the most common. There are also indications and records of the presence of the valuable Broad-tailed Yellowtail Butterflies. Tengzhi and neighboring Shanping are the two locations with the most moths in all of southern Taiwan. The major large moths are Luna Moth and Loepa katinka formosensis. At night, moths rest on the walls of buildings and look like "live specimens"; they appear in a variety of geometric shapes such as skulls, all of which are very dazzling and amazing!
Tengjhih Villa and Visitor Center provide food and accommodation services. Mountain climbing, hiking, sightseeing, bird-watching, butterfly-watching, moth-watching, flower-observing and researching nature are the main recreational activities. Walking along the linked trails such as the Taiwanese Azalea Trail, Sea of Trees trail, Waterfall Cycle trail, and Fitness Trail, visitors will find both the intellectual and emotional experience of this sightseeing area very enjoyable.
