With c. 28,000 species, orchids are one of the largest families of flowering plants, and they are also one of the most threatened, in part due to their complex life history strategies. Threats include habitat destruction and climate change, but many orchids are also threatened by unsustainable (often illegal and/or undocumented) harvest for horticulture, food or medicine. The level of these threats now outstrips our abilities to combat them at a species-by-species basis for all species in such a large group as Orchidaceae; if we are to be successful in conserving orchids for the future, we will need to develop approaches that allow us to address the threats on a broader scale to complement focused approaches for the species that are identified as being at the highest risk.
兰花有大约28000个品种，是开花植物中最大的科之一，也是受威胁最严重的科之一，部分原因在于其复杂的生活史策略。威胁包括栖息地破坏和气候变化，但许多兰花还受到园艺、食品或医药用途的不可持续（通常是非法和/或无记录）采集的威胁。这些威胁的程度现在已经超过了我们针对兰科这样一个大群体中的所有物种逐个进行应对的能力；如果我们要成功地为未来保护兰花，就需要制定能够让我们在更广泛范围内应对威胁的方法，以补充针对被确定为风险最高的物种的重点保护方法。
