If the species had been discovered later, it might have become extinct before being investigated. The tree faces considerable risks of extinction in its wild range due to deforestation, however it has been planted extensively in arboreta worldwide, where it has proved a popular and fast-growing ornamental plant. It is a particularly well-known example of a living fossil species. In 1941, the genus Metasequoia was reported by paleobotanist Shigeru Miki as a widely distributed extinct genus based on fossils, before attracting considerable attention a few years later when small populations were found alive in central China.
