在过去的50年里，全球植物灭绝率急剧上升。在夏威夷群岛，保护工作尤其具有挑战性，栖息地的丧失和与入侵物种的竞争威胁着本土植物物种的存在。目前，238种夏威夷特有植物在野外的数量不到50种。为了抵消这一令人生畏的统计数据，自然资源保护主义者应用了一套情境技术，以有效地保护许多濒临灭绝的植物物种。这篇文章强调了如何利用共同定位的种子库，微繁殖实验室和温室的综合保护方法，成功拯救和保护了许多受威胁的夏威夷植物物种。我们借鉴夏威夷植物保护的悠久历史的具体例子，详细的成功和持续的挑战与实施ofex situconservation技术。在这样做的过程中，我们讨论了如何植物微繁殖已成为一个criticalexsituconservation工具，以及如何将这种未充分利用的工具适合植物保护作为一个整体。我们还强调与外部组织的伙伴关系在确保有效开展保护工作方面发挥的重要作用。最后，利用从这些例子中吸取的经验教训，我们详细介绍和讨论了一个ex-situplant保护决策树，广泛适用于其他植物多样性保护关注的热点，以帮助确保区域和全球零灭绝的目标得到满足。
Global plant extinction rates have increased dramatically over the past 50 years. Conservation efforts are especially challenging across the Hawaiian archipelago, where habitat loss and competition with invasive species threaten the existence of native plant species. Currently, 238 endemic Hawaiian plant species have fewer than 50 individuals remaining in the wild. To counteract this daunting statistic, conservationists apply a suite ofex situtechniques to effectively safeguard the many threatened plant species from imminent extinction. This perspective piece highlights how an integrated conservation approach that utilizes a co-located seed bank, micropropagation laboratory, and greenhouse, has led to the successful rescue and conservation of many threatened Hawaiian plant species. We draw on specific examples from the long history of Hawaiian plant conservation to detail successes and ongoing challenges associated with the implementation ofex situconservation techniques. In doing so we discuss how plant micropropagation has emerged as a criticalex situconservation tool, and how this underutilized tool fits into plant conservation as a whole. We also emphasize the essential roles that partnerships with external organizations play in ensuring that effective conservation efforts are implemented. Last, using lessons learned from these examples we detail and discuss anex situplant conservation decision tree that is widely applicable to other plant diversity hotspots of conservation concern, in order to help ensure regional and global zero-extinction goals are met.
