Taiwan’s Mountain Paradise for the Nature-minded (Taiwan Business Topics)

Fushan Botanical Garden (福山植物園) is located in New Taipei City’s Wulai District, 10km as the crow flies from the Atayal village of Fushan. There is no road – and no legal access for hikers – from Greater Taipei, so visitors must come through Yilan County’s Yuanshan Township. But inconvenience is not the only reason why far fewer people visit Fushan than Taipei’s lovely but invariably crowded botanical garden. Permission to enter must be sought well in advance, and no more than 500 people are allowed in each day (600 on weekends and holidays).

Because educating the public about ecology is central to the garden’s mission, admission is free. Multimedia presentations are made every half hour inside the garden’s Nature Center, which is on the right about 1km before the main parking lot.

Covering 410 hectares, Fushan Botanical Garden accounts for approximately a third of Fushan Experimental Forest, which straddles the boundary between New Taipei and Yilan at elevations of 600 to 1,400 meters. The annual average temperature is 18.5 degrees Celsius, compared to 22 degrees Celsius in downtown Taipei. Annual average rainfall is 4,125 millimeters, about 40% more than in the capital. At 94.1%, Fushan’s annual average relative humidity is also considerably higher than Taipei’s.

The garden is not a reserve in the sense of aiming to absolutely minimize humanity’s impact on natural ecosystems. That is the goal of another part of Fushan Experimental Forest, the 333-hectare Hapen Nature Reserve to the immediate south of the garden. The northernmost segment of the forest is the 356-hectare Water Source Reserve, most of which is broad-leaf forest. Both reserves are strictly off-limits to the public.

Before the 1895-1945 Japanese colonization period, this area was inhabited by members of the Atayal indigenous tribe. Hapen Creek, a stream which flows through all three parts of the experimental forest, takes its name from a long-abandoned aboriginal settlement called Hbun. These days, the nearest permanent human residents are a handful of Hakka farming households at Shuanglianpi (雙連埤), more than five kilometers away. In good weather, the 17.2-hectare body of water after which the settlement is named is strikingly beautiful.

That is a big if, however. Fushan itself gets rain around 270 days per year, and fog is extremely common. Visitors should bring umbrellas or rainproof jackets, even if Taipei and Yilan City are bone dry.

The actual garden is divided into four zones, and it makes sense to explore them in the following order: Natural Classroom, Tree Exhibition, Forest Discovery, and Plants and Human Life.

The route outlined in the English-language section of the garden’s website is 3.01km long. Good footwear is essential as the pathways are mostly gravel, and the boardwalk beside the Aquatic Plants Pond can get slippery.

The pond is artificial but filled with life. Egrets and grey herons prey upon finger-length Candidia barbatus, an endemic minnow species. There are also turtles and frogs. One of the latter, Babina adenopleura, is found only in Taiwan and the Chinese mainland. During its March-to-August breeding season, the “ji-ji-ji” calls of male Babina adenopleura are especially audible, although the frogs themselves are hard to spot.

In total, 515 plant species belonging to 329 genera and 124 families thrive in the garden. There are some useful information boards around the garden; all are reproduced on the garden’s website. However, the labels in front of individual trees and plants provide the scientific and Chinese names only. Unless you carry a field guide, you may well find yourself googling names on your smartphone to find out more. Cellphone reception is serviceable in most of the garden.

Visitors familiar with Taiwan’s low-elevation mountain areas may well recognize one plant before they see any labels. What Taiwanese call “biting people cat” (咬人貓, Urtica thunbergiana) is a nettle whose sting is rightly feared. Not many city-dwellers know it can be cooked and eaten in soups.

The garden has few notably tall trees, because those that grow above the canopy are often blown over during typhoons. Unlike some other managed woodlands in Taiwan, fallen trees at Fushan are moved only if they block a pathway. The damp climate means the risk of forest fire is minimal, and rotting lumber plays an important role in arboreal ecosystems. Various creatures hide from predators or shelter from the sun inside dead trees. Beetles, spiders, and worms move and feed within the decaying wood. Most of the logs on the ground at Fushan host fungi.

Several of the species here have medicinal functions, including Mahonia japonica, sometimes called Japanese Holly-Grape. Scientific and common names notwithstanding, this perennial woody evergreen is native to Taiwan rather than Japan. It bears fruit that are no more than one centimeter in length and full of seeds, but quite edible raw or cooked. The seeds can be used to decoct a febrifuge – a substance that reduces fevers – while the roots and stems are said to have anti-rheumatic, detoxifying, and expectorant powers.

Standing out like a sore thumb – or in this case a sick tree – is a mature specimen of Prunus zippeliana. Most of its bark has come off, leaving the trunk and main branches a patchwork of ochre and clay brown, which is likely why this evergreen’s Chinese name is 黃土樹, “yellow-soil tree.” This sloughing is in fact proof of good health, an entirely normal mechanism to shed borers and parasites...
