We systematically assess the herpetofaunal diversity of the Serra do Pingano Forest Ecosystem (SPFE) and additional localities throughout the northern Angolan province of Uíge during four independent Rapid Assessment (RA) field campaigns held between 2013 and 2019. These assessments represent the first systematic surveys of amphibians and reptiles from the province, and thus we provide the first province-wide species list. We collected data on the status and current threats to amphibians and reptiles in the proposed Serra do Pingano Rainforest National Park and were able to document 33 species of reptiles from Uíge province. Of the 33 species recorded from the province, 10 species are exclusively found in the SPFE. Amphibian surveys yielded 47 amphibian species from the province. These include 14 new country records and additional records that may represent undescribed species. This raises the amphibian count for Angola to at least 133 species, which includes 18 species exclusively found within the SPFE. Species-richness estimators indicate that more species should be detected if survey efforts are intensified. The species composition in the SPFE is unique and consists of a high proportion of forest specialists with restricted ranges and species found nowhere else in the country. This emphasizes today’s paramount importance of the SPFE, which is threatened by increasing agricultural encroachment and uncontrolled timber extraction and charcoal production. These principal factors need to be controlled and/or abandoned in already impacted areas. Conservation strategies should particularly consider the strict protection of remaining intact forests and both lentic and lotic aquatic systems. They are not only crucial for safeguarding a significant number of species that depend on these habitats for reproduction; they also provide key ecosystem services to the local population. Angola, and Uíge province in particular, is at a crossroads concerning decisions and trade-offs among utilization, conservation, and preservation of its forests and, thus, substantial parts of the country’s biodiversity. The establishment of a National Protected Area in the Serra do Pingano Ecosystem is therefore a necessary and urgently needed first step towards protecting Angola’s national biodiversity heritage.

濒临灭绝:对安哥拉北部威热省拟建的 Serra do Pingano 雨林国家公园的首次爬虫学评估

在 2013 年至 2019 年期间举行的四次独立快速评估 (RA) 实地活动期间,我们系统地评估了 Serra do Pingano 森林生态系统 (SPFE) 和整个安哥拉北部威热省其他地区的爬行动物多样性。这些评估代表了首次系统性调查来自全省的两栖动物和爬行动物,因此我们提供了第一个全省物种清单。我们收集了有关拟建的 Serra do Pingano 雨林国家公园中两栖动物和爬行动物的现状和当前威胁的数据,并能够记录威热省的 33 种爬行动物。在该省记录的 33 个物种中,有 10 个物种仅在 SPFE 中发现。两栖动物调查从该省产生了 47 种两栖动物。其中包括 14 个新的国家记录和可能代表未描述物种的其他记录。这使安哥拉的两栖动物数量增加到至少 133 种,其中包括 18 种仅在 SPFE 中发现。物种丰富度估计表明,如果加强调查工作,应该发现更多物种。SPFE 中的物种组成是独一无二的,其中包括高比例的森林专家,范围有限,物种在该国其他任何地方都找不到。这强调了 SPFE 在今天的极端重要性,它受到日益增加的农业侵占和不受控制的木材开采和木炭生产的威胁。在已经受到影响的地区,需要控制和/或放弃这些主要因素。保护策略应特别考虑严格保护剩余的完整森林以及水生系统和水生系统。它们不仅对于保护依赖这些栖息地进行繁殖的大量物种至关重要;它们还为当地居民提供重要的生态系统服务。安哥拉,尤其是威热省,正处于森林利用、保护和保护以及该国大部分生物多样性之间的决策和权衡的十字路口。因此,在 Serra do Pingano 生态系统中建立国家保护区是保护安哥拉国家生物多样性遗产的必要和迫切需要的第一步。它们不仅对于保护依赖这些栖息地进行繁殖的大量物种至关重要;它们还为当地居民提供重要的生态系统服务。安哥拉,尤其是威热省,正处于森林利用、保护和保护以及该国大部分生物多样性之间的决策和权衡的十字路口。因此,在 Serra do Pingano 生态系统中建立国家保护区是保护安哥拉国家生物多样性遗产的必要和迫切需要的第一步。它们不仅对于保护依赖这些栖息地进行繁殖的大量物种至关重要;它们还为当地居民提供重要的生态系统服务。安哥拉,尤其是威热省,正处于森林利用、保护和保护以及该国大部分生物多样性之间的决策和权衡的十字路口。因此,在 Serra do Pingano 生态系统中建立国家保护区是保护安哥拉国家生物多样性遗产的必要和迫切需要的第一步。正处于利用、保护和保护森林以及该国生物多样性的重要部分之间的决策和权衡的十字路口。因此,在 Serra do Pingano 生态系统中建立国家保护区是保护安哥拉国家生物多样性遗产的必要和迫切需要的第一步。正处于利用、保护和保护森林以及该国生物多样性的重要部分之间的决策和权衡的十字路口。因此,在 Serra do Pingano 生态系统中建立国家保护区是保护安哥拉国家生物多样性遗产的必要和迫切需要的第一步。
