In a Nutshell:

* Thuja sutchuenensis (Sichuan thuja) is a species of thuja, an evergreen coniferous tree in the cypress family Cupressaceae. It is native to China, where it is a critically endangered local endemic in Chengkou County (Chongqing Municipality, formerly part of Sichuan province), on the southern slope of the Daba Mountains. more...

* It is a small or medium-sized tree, reaching possibly 20 m tall, though no trees of this size are currently known. The foliage forms in flat sprays with scale-like leaves 1.5-4 mm long, green above, and with narrow white stomatal bands below. The cones are oval, green ripening brown, 5-8 mm long and 3-4.2 mm broad (opening to 7 mm broad), with 8-10 overlapping scales. more...

* It was first described in 1899 from specimens collected by the French botanist Paul Guillaume Farges in 1892 and 1900, but was not seen again thereafter, despite many searches, for almost 100 years and was presumed to be extinct due to over-cutting for its valuable scented wood. A small number of specimens were however rediscovered in 1999, growing on very inaccessible steep ridges close to (or at the same site) where Farges had first found it. The area of its occurrence has now been designated a Special Protection Area in order to protect the species. more...

* Grows on limestone, mostly on ridges or steep S-facing slopes, at (800-)1000-1500(-2100) m elevation. Climate is humid warm temperate, with a January mean of 2.4°C, a July mean of 24.8°C, and a mean annual precipitation of 1418 mm. Soils are usually thin, but rich in organic matter and accordingly, slightly acidic (pH 6.2-7). more...

* The surviving population is estimated to include trees 500 to 600 years old (People's Daily, 2001.04.15). more...

* At the time the species was rediscovered, local people used the soft, easily-worked wood for home construction, shingles, and other uses requiring decay resistance (Xiang et al. 2002). more...

* The spelling of the specific epithet derives from Sutchuen (French for Sichuan), plus the ending -ensis (originating from). more...
