Chamaecyparis formosensis (Formosan cypress, Taiwan cypress, Taiwan red cypress;

habitat loss and over-cutting for its valuable timber.[1][2][3]

Growth

It is a slow-growing, but long-lived and ultimately large to very large

coniferous tree growing to 55–60 m tall with a trunk up to 7 m in diameter. The bark is red-brown, vertically fissured and with a stringy texture. The foliage is arranged in flat sprays; adult leaves are scale-like, 1–3 mm long, with pointed tips, green both above and below with only an inconspicuous stomatal band at the base of each scale-leaf; they are arranged in opposite decussate pairs on the shoots. The juvenile leaves, found on young seedlings, are needle-like, 4–8 mm long, soft and glaucous bluish-green. The cones are ovoid-oblong, 6–12 mm long and 4–8 mm diameter, with 8–16 scales arranged in opposite pairs, maturing in autumn about 7–8 months after pollination.[2]

Related species

It is most closely related to the Japanese Chamaecyparis pisifera (sawara cypress), which differs in smaller globose cones 4–8 mm long with 6–10 scales.[2]

Characteristics

The wood is soft, very resistant to decay, and strongly scented; it is highly valued in traditional Taiwanese building, particularly for temples and shrines. This has led to excessive harvesting, resulting in the species now being endangered. A small number of the oldest and largest specimens are protected as national monuments, but much of the general population of the species still remains unprotected.[2]

Essential oil distilled from its wood is uniquely scented and highly valued.[4]

Notable examples

Sacred Tree of Alishan

The Sacred Tree of Alishan was a 3,000-year-old Taiwan red cypress which died from a lightning strike in 1956. The trunk remained standing until 1998. Due to its sacred status it was left alone by the Japanese when they deforested the surrounding area.[5]
