This dataset contains the plot survey data of terrestrial vascular plants on Lyudao (Green Island). The purpose of the survey is to investigate and compare the diversity and changes in plant communities on the island. In the first year of the project, 158 plots established in the report by Chen and Lu (2008) were surveyed, focusing solely on plant coverage data collection to provide baseline information for selecting long-term monitoring plots. In the second year, 25 of these plots were selected for quarterly re-surveys, and in the third year, monitoring continued for two additional quarters.

Datos del proyecto
Establishing the Lyudao LTSER Core Observation Platform This project aims to enhance long-term socio-ecological research capacity on Lyudao (Green Island), Taiwan’s first offshore Long-Term Socio-Ecological Research (LTSER) station supported by the National Science and Technology Council (NSTC). Compared with stations on Taiwan’s main island, Lyudao requires significantly greater logistical effort for field surveys, stakeholder engagement, and issue assessment. To improve coordination and support on-the-ground operations, the project collaborates with the Marine Science Center of the Biodiversity Research Center, Academia Sinica, to establish the “Lyudao LTSER Core Observation Platform Office” at the Lyudao Marine Research Station. The office conducts routine tasks including: 1.Operation and maintenance of marine and terrestrial environmental monitoring instruments 2.Assistance with data collection, management, and open data dissemination 3.Engagement and communication with local stakeholders 4.Organization of workshops and outreach activities 5.Logistical and research support for field teams The project also compiles socio-ecological research related to Lyudao—including humanistic studies, socio-economic analyses, governance structures, and ecological research—and maps local stakeholder networks across private and public sectors. Workshops will be organized to identify emerging socio-economic conflicts, governance transition issues, and opportunities for collaboration. A communication platform (website and social media) will be established to enhance stakeholder interaction. The project further collects, manages, shares, and visualizes long-term social, environmental, and ecological observations following FAIR data principles. Data will be integrated into a platform for long-term storage, analysis, and open access to support scientific research, policy development, and local governance.

| Descripción del área de estudio | Lyudao (Green Island) is the fourth-largest offshore island of Taiwan, located along the Kuroshio Current. The island hosts well-developed coral reefs that support rich biodiversity and provide essential ecosystem services. Historically a fishery-based society, Lyudao has transformed into a tourism-driven socio-ecological system, receiving nearly 400,000 visitors annually—approximately 100 times its registered population. The coral reef ecosystem is highly sensitive to disturbances such as climate change and intensive human activities. Understanding whether Lyudao can remain sustainable as a small Pacific island requires long-term monitoring of both ecological and social systems. Continuous observation of environmental conditions, marine and terrestrial ecosystems, and socio-economic dynamics is crucial for assessing ecosystem health, identifying vulnerabilities, and informing conservation and governance strategies. |
| Descripción del diseño | The Lyudao LTSER Station serves as Taiwan’s model platform for island sustainability science. Small islands such as Lyudao possess limited environmental and socio-economic buffers, making them more vulnerable to climate change, global disturbances, and extreme events such as the COVID-19 pandemic. The station promotes the conservation of Lyudao’s coral reef ecosystem by highlighting its role as the foundation of the island’s socio-economic structure. Recognizing the interdependence between ecological integrity and human well-being, the project implements long-term, systematic observations across three domains: 1.Socio-ecological observations: socio-economic surveys, land/marine resource-use assessments, and development of indicators for sustainability. 2.Environmental observations: climate and hydrological monitoring, including microclimate towers and water-quality sensors, complemented by data from governmental agencies. 3.Ecological observations: monitoring terrestrial vegetation, passive acoustics, coral reef fish assemblages, coral diversity, recruitment, bleaching events, and marine ecosystem conditions. These integrated observations support future research on governance transitions related to food systems, energy, transportation, and ecological resilience. Through systematic data collection, methodological transparency, and FAIR-compliant data sharing, the Lyudao LTSER Station contributes to national development, conservation planning, and global sustainability science. |

Métodos de muestreo
The plot survey method in the first year of the project: 1. Following the plot coordinate information provided in the report by Chen & Lu (2008), the TWD97 coordinate data were converted to the WGS 84 coordinate system (EPSG:4326) using QGIS v.3.28, and the locations were marked on a topographic map. 2. Based on these coordinates, field teams attempted to reach locations within 5 meters of the original coordinates. The positions were re-located using a handheld GPS navigator (GPSmap 60CSx, Garmin Inc., Olathe, KS) or a mobile phone, and both the point information and GPS accuracy (error range) were recorded. 3. A square plot was established centered on each marked point. The type of plot was determined according to the physiognomy and height of the dominant vegetation at the site and classified into three categories: grassland plots (25 m²), tall herb or shrub plots (90 m²), and forest plots (250 m²). 4. The Braun-Blanquet method was used to record all vascular plant species occurring within each plot, estimating the coverage of each species as a percentage (%). Each species was also assigned to one of seven vegetation strata: herb layer (E1), shrub layer (E2), canopy layer (E3), emergent layer (E4), tree seedlings (J), lianas (L), and epiphytes (EP). The plot re-survey method in the second and third year of the project:
| Área de Estudio | In the first year, 129 plots were surveyed (with adjustments made as necessary according to accessibility and terrain conditions). In the second and third years, 25 of these plots were selected for quarterly re-surveys. |

Descripción de la metodología paso a paso:
- Re-surveys were conducted based on the existing plot locations from the report by Chen & Lu (2008), recording the species composition and coverage of vascular plants within each plot. The data fields and formats were designed to serve as the foundation for subsequent alignment with the Darwin Core / IPT standards.
