The current decline in global biodiversity is most evident in amphibians with 41% percent of all species worldwide classified as threatened with extinction. Hence, a major challenge in amphibian conservation is the high number of threatened species, leading to a common approach of identifying priority species and regions for conservation efforts. As a part of one of 36 globally designated biodiversity hotspots, Vietnam is considered to be of particular importance for conservation action. To improve amphibian conservation in Vietnam, this study provides an updated species list and assesses their threat status by compiling data from a variety of sources. Furthermore, a Zoological Information Management System (ZIMS) analysis was conducted to determine the representation of extant amphibians from Vietnam in zoos worldwide. The batrachofauna of Vietnam is characterized by a high level of species richness and local endemism as well as a high rate of new discoveries, with more than half of the endemic species reported exclusively from their type locality, making them especially vulnerable to extinction. Up to 18% of all amphibians extant in Vietnam and 28% of endemic species are classified as threatened with extinction by the IUCN. In many cases, the IUCN Red List status is either missing or outdated, highlighting the urgent need of action. Around 14% of endemic amphibian species have been recorded exclusively from unprotected areas, suggesting prioritization for further research and conservation measures. The continuing decline in many species remains an unresolved problem. As a guide for future research and conservation measures, a list of the top 57 species was compiled. In addition, according to the ZIMS analysis, only 8% of threatened and 3% of endemic amphibian taxa from Vietnam are currently kept in zoos worldwide, and a richness analysis revealed that the highest density of husbandries is found in Europe and North America. To achieve maximum outcome for the conservation of threatened species, this study recommends a general shift by zoos towards maintaining species in greater need of captive assurance populations and breeding programs to support integrative strategies that combine in situ and ex situ conservation efforts following the IUCN’s One Plan Approach.

评估越南两栖动物的威胁状况 - 单一计划方法的实施

 目前全球生物多样性的下降在两栖动物中最为明显，全球 41% 的物种被列为濒临灭绝的物种。因此，两栖动物保护的一个主要挑战是大量受威胁物种，这导致了一种确定优先物种和区域以进行保护工作的共同方法。作为全球指定的 36 个生物多样性热点之一，越南被认为对保护行动特别重要。为了改善越南的两栖动物保护，本研究提供了更新的物种清单，并通过汇编来自各种来源的数据来评估它们的威胁状况。此外，还进行了动物学信息管理系统 (ZIMS) 分析，以确定来自越南的现存两栖动物在全球动物园中的代表性。越南蝙蝠鱼的特点是物种丰富度高、地方特有性高、新发现率高，超过一半的地方性物种仅来自其类型地点，这使得它们特别容易灭绝。多达 18% 的越南现存两栖动物和 28% 的特有物种被 IUCN 列为濒临灭绝的物种。在许多情况下，IUCN 红色名录状态要么缺失，要么已过时，这凸显了采取行动的紧迫性。大约 14% 的地方性两栖动物物种完全来自未受保护的地区，这表明优先考虑进一步研究和保护措施。许多物种的持续减少仍然是一个未解决的问题。作为未来研究和保护措施的指南，编制了前 57 个物种的清单。此外，根据 ZIMS 分析，目前全球动物园仅饲养了来自越南的 8% 的受威胁和 3% 的地方性两栖动物类群，丰富度分析显示，欧洲和北美的饲养密度最高。为了在保护受威胁物种方面取得最大成果，本研究建议动物园普遍转向维持更需要圈养保证种群和繁殖计划的物种，以支持根据 IUCN 的单一计划将就地和异地保护工作相结合的综合战略方法。丰富度分析显示，欧洲和北美的畜牧业密度最高。为了在保护受威胁物种方面取得最大成果，本研究建议动物园普遍转向维持更需要圈养保证种群和繁殖计划的物种，以支持根据 IUCN 的单一计划将就地和异地保护工作相结合的综合战略方法。丰富度分析显示，欧洲和北美的畜牧业密度最高。为了在保护受威胁物种方面取得最大成果，本研究建议动物园普遍转向维持更需要圈养保证种群和繁殖计划的物种，以支持根据 IUCN 的单一计划将就地和异地保护工作相结合的综合战略方法。
