Descrição
Terrestrial Soundscape Monitoring – bird sound identification This dataset contains terrestrial soundscape monitoring data collected within the forest ecosystem of Lyudao (Green Island) by the Lyudao Long-Term Socio-Ecological Research (LTSER) Core Observation Platform. The project is supported by the National Science and Technology Council (NSTC). Acoustic data collection and analysis were conducted by the Eco-Acoustics and Spatial Ecology Lab at the Biodiversity Research Center, Academia Sinica.
Survey Locations Four acoustic monitoring stations were established in the broadleaf forest ecosystem of Lyudao (Green Island): 1. Lighthouse (N22.675°, E121.469°) 2. Youzi Lake (N22.666°, E121.508°) 3. Guoshan Trail (N22.649°, E121.488°) 4. Baisha (N22.640°, E121.495°)
Survey Frequency and Period Continuous acoustic monitoring began in February 2023. The program includes both audible and ultrasonic recordings: Audible recordings: Scheduled 24 hours a day, recording 1-minute audio every 15 minutes. Ultrasonic recordings: Conducted mainly at night, from 16:30 to 07:30 the next morning, also recording 1-minute ultrasonic audio every 15 minutes. Project assistants at the Lyudao Field Station of Academia Sinica's Biodiversity Research Center performed the monitoring tasks. Battery and memory card replacements were carried out every 45 days, after which the recording data were transported back to the Eco-Acoustics and Spatial Ecology Lab for analysis.
Equipment and Installation The project utilized Song Meter SM4 and SM4BAT FS recorders manufactured by Wildlife Acoustics (USA), equipped with built-in audible microphones and U2 ultrasonic microphones. Sampling rates were 44.1 kHz for audible recordings and 384 kHz for ultrasonic recordings.

Dados Sobre o Projeto
1. Establishing the “Lyudao LTSER Core Observation Platform Office” at the Academia Sinica Lyudao Marine Research Station The Lyudao Long-Term Socio-Ecological Research (LTSER) Core Observation Platform (hereafter referred to as the Lyudao Station) is the first offshore island platform among the LTSER stations supported by the National Science and Technology Council (NSTC). Compared with stations located on Taiwan’s main island, the Lyudao Station requires significantly more transportation time for field surveys, issue assessment, and engagement with local stakeholders. To improve communication with local stakeholders on Lyudao and to increase the efficiency of researchers’ field observations and data collection, this project collaborates with the Marine Science Center of the Biodiversity Research Center, Academia Sinica, based in Gongguan Village on Lyudao. Together, we established the “Lyudao LTSER Core Observation Platform Office” within the Lyudao Marine Research Station. The office will regularly carry out the following tasks: Operation and maintenance of marine and terrestrial environmental monitoring instruments Assistance with data collection, storage, and open data dissemination Communication and issue collection with local stakeholders Organization of workshops and engagement activities Logistical support for researchers conducting fieldwork on the island 2. Compilation of Research Reports and Stakeholder Mapping Over the next three years, the primary objectives of the Lyudao Station include: Compiling past research reports related to Lyudao’s humanities, socioeconomics, social–ecological systems, governance structures, and natural ecology—such as published journal articles (Chinese and English), dissertations, government-commissioned project reports, and conference proceedings. Mapping current stakeholders under the island’s socio-economic framework. Private sector stakeholders: indigenous residents, new immigrants, fishers and fishermen’s associations, tourism operators, diving industry, guesthouse owners, restaurants, shop owners, local opinion leaders, and NGOs. Public sector stakeholders: Taitung County Government, Lyudao Township Office, Township Representatives Council, East Coast National Scenic Area Headquarters of the Tourism Administration, and the Coast Guard Administration’s Lyudao Squadron. Organizing workshops to identify, discuss, and expand key socio-economic conflicts and future governance transition issues. Establishing communication platforms—such as a website, Facebook, Instagram, and Twitter—to strengthen engagement and dialogue among local stakeholders. 3. Collection, Storage, Open Sharing, and Visualization of Social, Environmental, and Ecological Observation Data The observation program at the Lyudao Station is divided into three major categories: socio-ecological, environmental, and ecological data. Socio-ecological data Collected through in-depth socio-economic surveys and interviews to understand Lyudao’s economic activities, land use, and marine resource use. These data will form the basis for developing indicator systems and constructing an information platform. Environmental data In addition to collecting existing monitoring datasets from the Central Weather Administration, Ocean Affairs Council, and the Lyudao Airport, the project will install two microclimate observation towers and conduct water-quality measurements using water-quality sensors, supplementing gaps in existing monitoring programs. Ecological data Observation items include: Terrestrial vegetation Passive acoustic monitoring Spatiotemporal changes in coral reef fish assemblages Coral diversity and reef community structure Recruitment and coral bleaching Marine ecosystem conditions and coral health indicators After data collection, the project will implement data management following FAIR principles (Findable, Accessible, Interoperable, Reusable). A data platform will be developed for long-term storage, management, integration of external datasets, and open sharing to support scientific research, policy development, and local governance applications.

| Descrição da Área de Estudo | The coral reef ecosystem is one of the most important marine ecosystems in Taiwan. It not only conserves rich biodiversity, but also provides key resources to support various social and economic activities. Lyudao (Green Island) is the fourth largest island among Taiwan's outlying islands. Coral reefs are developed along the coast of the Lyudao due to the influence of the mainstream of the Kuroshio Current. The coral reef ecosystem of Lyudao has supported Lyudao from being fishery in its early years, but it has now transformed into a tourism-based social-ecological system. Nearly 400,000 tourists visit each year, which is 100 times the registered population of Lyudao. However, under the interference of human activities and climate change, whether Lyudao can be sustainable as a small island in the Pacific Ocean can only be known through long-term social and ecological data collection and observation, and follow-up research and analysis. |
| Descrição do Design | The Long-Term Socio-Ecological Research (LTSER) Core Observation Platform in Taiwan dedicated to island sustainability science, the Lyudao LTSER Station is expected to serve as a model for future island-based platforms across Taiwan. Small islands like Lyudao are inherently more vulnerable than Taiwan’s main island, which possesses greater social and natural resources. Combined with the unpredictable challenges of climate change and the severe impacts of events such as the COVID-19 pandemic, achieving sustainability on small islands has become even more difficult. By promoting the conservation of coral reef ecosystems and highlighting the ecosystem services they provide, the station aims to help stakeholders recognize that a healthy “ridge-to-reef” ecological system forms the foundation of Lyudao’s existing socio-economic structure. At the same time, this ecological system is itself vulnerable to climate change. Therefore, the long-term and systematic collection of environmental, ecological, and social data is essential for understanding ecosystem health and supporting future research related to sustainable governance transitions—such as food systems, energy, transportation, and ecosystem resilience. Through these efforts, the Lyudao LTSER Station will make important contributions to academic research and national development |

| Controle de Qualidade | 辨識流程採用中華民國野鳥學會 2023 年臺灣鳥類清單，去除迷鳥後作為 BirdNET 分析輸入名錄，並設定 min_conf = 0.1。後續將綠島過去無調查紀錄或 eBird 無目擊紀錄的鳥種剔除，僅保留信心分數 ≥ 0.5 的偵測結果，以確保物種出現紀錄的可信度。 The identification process used the 2023 Taiwan Bird Checklist from the Taiwan Wild Bird Federation. Vagrant species were removed to create the input list for BirdNET analysis, with the minimum confidence threshold set to 0.1. Subsequently, bird species with no previous records on Lyudao or no sightings in eBird were excluded, and only detections with a confidence score ≥ 0.5 were retained to ensure the reliability of species occurrence records. |
Descrição dos passos do método:
- 鳥音辨識流程：首先使用 BirdNET 2.4 (Kahl, et al., 2021) 與自建生物聲音辨識工具進行初步辨識；再依據臺灣鳥類名錄及 eBird 資料進行物種過濾；最後輸出物種出現紀錄，並於結果中對應至臺灣物種名錄 (TaiCOL) 的 taxonID、scientificNameID 等標準欄位。 Bird sound identification workflow: First, preliminary identification was performed using BirdNET 2.4 (Kahl, et al., 2021) and a custom bioacoustic recognition tool. Species were then filtered based on the Taiwan Bird Checklist and eBird records. Finally, species occurrence records were generated, with results mapped to standard fields such as taxonID and scientificNameID according to the TaiCOL taxonomy.
