Betel nut agroforestry had quickly grown to occupy more than 1% of the land in Taiwan, often taking the place of secondary forests. While agroforestry systems can help mitigate biodiversity loss by preserving habitat structure and providing essential ecological services, the ecological role of betel nut plantations - particularly their impact on avian communities - remains largely understudied. Birds, as sensitive indicators of environmental change, offer valuable insights into habitat quality and biodiversity health. To address this knowledge gap, we conducted standardised point count surveys to collect data on bird species composition and abundance.
This was the first avian dataset focused on betel nut agroforestry, providing detailed bird occurrence data for betel nut plantations and secondary forests. The dataset is particularly useful for understanding how agriculture alters ecological services in human-modified landscapes. Data were collected during the breeding seasons (March to May) of 2015 and 2016 across 80 sites in four counties of central Taiwan. Each site included five sampling points, with avian community data recorded twice per season at each point. This publicly available dataset on GBIF offers valuable insights into avian biodiversity and habitat use in agricultural ecosystems.
槟榔农林复合经营迅速发展，在台湾占据了超过1%的土地，常常取代次生林。虽然农林复合经营系统可以通过保护栖息地结构和提供重要的生态服务来帮助减轻生物多样性丧失，但槟榔种植园的生态作用——尤其是它们对鸟类群落的影响——在很大程度上仍未得到充分研究。鸟类作为环境变化的敏感指标，能为栖息地质量和生物多样性健康提供有价值的见解。为填补这一知识空白，我们进行了标准化的点计数调查，以收集鸟类物种组成和数量的数据。
这是首个专注于槟榔农林复合经营的鸟类数据集，提供了槟榔种植园和次生林详细的鸟类出现数据。该数据集对于理解农业如何改变人类改造景观中的生态服务特别有用。数据于2015年和2016年繁殖季节（3月至5月）在台湾中部四个县的80个地点收集。每个地点包括五个采样点，每个季节在每个点记录两次鸟类群落数据。这个在全球生物多样性信息机构（GBIF）上公开可用的数据集为农业生态系统中的鸟类生物多样性和栖息地利用提供了有价值的见解。
