摘要

摘要 湿地是生态景观中生物多样性较高的岛屿,为社会提供重要的生态系统服务。人类活动导致湿地退化,没有生物多样性丧失或改变迹象的湿地已变得越来越罕见。湿地生物多样性丧失的加剧对当地经济和这些系统提供的生态系统服务产生了负面影响。我们响应南非国家生物多样性评估(NBA)的号召,在南部非洲湿地持续退化的背景下记录湿地生物多样性。从 2019 年 6 月到 2020 年 12 月,我们采用滚动网格布局对金门高地国家公园(GGHNP)24 个地点的高海拔湿地的声景进行了监测。我们发现了 35.9% 以前在金门高地国家公园临时目击记录的鸟类物种,其中 68.1% 是湿地必生物种。此外,我们还为保护区的鸟类多样性贡献了10.2%的新物种记录,其中包括24种被世界自然保护联盟(IUCN)视为濒危物种的鸟类。我们的远程监测技术首次使用远程声学设备对南非的高海拔湿地进行了连续监测,从而为全国鸟类理事会(NBA)的呼吁做出了宝贵贡献。

Passive acoustic monitoring detects new records of globally threatened birds in a high-elevation wetland (Free State, South Africa)
Summary Wetlands act as islands of high biodiversity within the ecological landscape and provide crucial ecosystem services to society. Anthropogenic activities are driving wetland degradation and it has become increasingly rare to find wetlands that do not show signs of biodiversity loss or alteration. The exacerbated loss of biodiversity in wetlands has a negative impact on the local economy and ecosystem services provided by these systems. We responded to the South African National Biodiversity Assessment (NBA) call to document wetland biodiversity against the backdrop of sustained wetland degradation in southern Africa. We monitored the soundscape of a high-elevation wetland in the Golden Gate Highlands National Park (GGHNP) from June 2019 to December 2020 across 24 localities using a rolling grid layout. We detected 35.9% of the avian species previously recorded from ad hoc sightings in the GGHNP of which 68.1% are wetland obligate species. We contributed an additional 10.2% new species records to the avian diversity of the GGHNP, including 24 species that are considered threatened by the International Union for Conservation of Nature (IUCN). Our remote monitoring technique enabled the first ever continuous monitoring using remote acoustic equipment for a high-elevation wetland in South Africa, thus providing a valuable contribution to the NBA call.

期刊介绍: Bird Conservation International is a quarterly peer-reviewed journal that seeks to promote worldwide research and action for the conservation of birds and the habitats upon which they depend. The official journal of BirdLife International, it provides stimulating, international and up-to-date coverage of a broad range of conservation topics, using birds to illuminate wider issues of biodiversity, conservation and sustainable resource use. It publishes original papers and reviews, including targeted articles and recommendations by leading experts.
