| Abstract | Plant species with small habitat ranges and specific edaphic requirements are highly vulnerable to extinction and thus require enhanced attention in biodiversity conservation. This study was designed to explore the challenges of protecting such plant species by evaluating the in situ and ex situ conservation capacities available for Thailand's species of the mega‐diverse plant genus Begonia L. A comprehensive assessment of occurrence records across the country was conducted to evaluate the spatial distribution of Begonia diversity in Thailand, identify biodiversity hotspots, assess the extinction threats faced by the 60 Begonia species known in the country, and identify existing conservation capacities and potential gaps. The results show that 78% of Begonia species in Thailand are vulnerable to extinction, with the Northern floristic region identified as both a Begonia species hotspot and a region with major conservation gaps. While in situ conservation efforts have been successful in covering over 88% of the species, they have failed to provide the protection required to achieve zero extinction. Ex situ conservation capacities are poorly developed, with only 13% of species present in botanical gardens, and no seed banking or other related activities have been initiated. This evaluation presents a sharply contrasting message: on one hand, Thailand has assembled substantial capacities to protect these plants through established national parks and other protected areas, but on the other hand, essential capacities are still lacking to render the zero extinction target achievable. We advocate for the implementation of a multi‐component conservation strategy to enable Thailand to move towards zero species extinction, even for plant species with narrow habitat ranges and high edaphic specialisation. 栖息地范围小且环境特异性高的植物物种面临极高的灭绝风险,因此需要在生物多样性保护方面给予更多关注。本研究的目的是通过评估就地和异地保护的能力,明确保护此类植物物种所面临的挑战,以保护泰国多样性极高的秋海棠属物种。为此,研究人员对泰国全国范围内的秋海棠物种出现记录进行了综合评估,以了解泰国秋海棠多样性的空间分布,确定生物多样性热点地区以及60个面临灭绝威胁的物种,并最终确定现有保护能力和保护的不足。结果表明,泰国78%的秋海棠物种濒临灭绝,而北部花卉区不仅是秋海棠物种的热点地区,也是主要的保护空白区。就地保护工作成功覆盖了88%以上的物种,但未能提供实现零灭绝所需的保护。异地保护能力很差,只有13%的秋海棠物种在植物园中展示,种子库及相关行动都尚未开展。本评估报告提供了一种“表里不一”的信息。一方面,泰国已经建立了国家公园和其他保护区,具备了保护这些植物的强大能力。另一方面,泰国仍然缺乏实现物种零灭绝目标的能力。在此,我们提倡实施多重保护的策略,进一步促使泰国实现物种零灭绝,即使是栖息地范围窄、环境特异性高的植物物种也不例外。【审阅:周聪】 Assess species vulnerability by utilising occurrence data from fieldwork and online historical records to reliably evaluate key criteria such as area of occupancy, endemism, number of recorded locations, and the proportion of these locations within protected areas.

Most species within the mega‐diverse plant genus Begonia are particularly vulnerable due to their rarity, which is a result of their high ecological specialisation. While existing natural parks and other protection areas offer refuge for many species—covering nearly 90% of the Begonia species diversity in Thailand—additional conservation measures are required to achieve the goal of zero extinction. These measures may include the establishment of new micro‐protection sites or the development of ex situ conservation protocols. As a consequence, effective biodiversity conservation aimed at zero extinction cannot rely solely on the design of large‐scale protected areas but must also include highly targeted actions focused on rare species facing significant extinction threats. In short, the conservation of rare plant species is best approached by implementing a multi‐component conservation strategy, which is key to ensuring the long‐term viability of these species and moving closer to the goal of zero species extinction. 评估稀有植物物种因人类活动而面临的灭绝风险,是提高我们实现“零灭绝”目标的一个紧迫问题。秋海棠属植物种类繁多,由于其高度生态特异性造成的稀有性,大多数物种都特别脆弱。现有的自然公园和其他保护区为许多物种提供了庇护,例如在泰国,近 90% 的海棠物种多样性都得到了保护。然而,要实现“零灭绝”目标,还需要采取更多的保护措施,无论是以新的微型保护区的形式,还是以异地保护协议的形式。因此,要有效保护生物多样性,实现零灭绝,不能仅仅依靠设计大规模Title的保护区,还要采取高度针对性的行动,重点保护面临高度灭绝威胁的稀有物种。简而言之,保护珍稀植物物种的最佳途径是实施多重保护战略,以此实现物种零灭绝的目标,确保这些植物物种的长期生存能力。 The study evaluates the conservation capacities for Begonia L. genus in Thailand, which is a vulnerable plant species. Results show that 78% of Begonia species in Thailand are classified as threatened, and the Northern floristic region is a hotspot for the genus. The study highlights the importance of evaluating current conservation capacities and implementing a multi‐strategy approach to ensure their long‐term viability and achieve the goal of zero species extinction. |
