**Dataset Description: Geographical Distribution and Climate Data of *Cycas taiwaniana* (Taiwanese Cycad)**This dataset contains the geographical distribution and climate data for *Cycas taiwaniana*, focusing on its presence across regions in Fujian, Guangdong, and Hainan provinces of China. The dataset includes geographical coordinates (longitude and latitude), monthly climate data (minimum and maximum temperature, and precipitation) across different months, as well as bioclimatic variables based on the WorldClim dataset.**Temporal and Spatial Information** The data covers long-term climate information, with monthly data for each location recorded over a 12-month period (January to December). The dataset includes spatial data in terms of longitude and latitude, corresponding to various locations where *Cycas taiwaniana* populations are present. The spatial resolution is specific to each point location, and the temporal resolution reflects the monthly climate data for each year.**Data Structure and Units** The dataset consists of 36 records, each representing a unique location with corresponding climate and geographical data. The table includes the following columns: 1. **No.**: Unique identifier for each data record 2. **Longitude**: Geographic longitude in decimal degrees 3. **Latitude**: Geographic latitude in decimal degrees 4. **tmin1 to tmin12**: Minimum temperature (°C) for each month (January to December) 5. **tmax1 to tmax12**: Maximum temperature (°C) for each month (January to December) 6. **prec1 to prec12**: Precipitation (mm) for each month (January to December) 7. **bio1 to bio19**: Bioclimatic variables (e.g., annual mean temperature, temperature seasonality, precipitation, etc.) derived from WorldClim data (unit varies depending on the variable)The units for each measurement are as follows: - Temperature: Degrees Celsius (°C) - Precipitation: Millimeters (mm) - Bioclimatic variables: Varies depending on the specific variable (e.g., °C, mm)**Data Gaps and Missing Values** The dataset contains some missing values, particularly in the "precipitation" columns for certain months and locations. These missing values may result from gaps in climate station data or limitations in data collection for specific regions. Missing values are indicated as "NA" (Not Available) in the dataset. In cases where data gaps exist, estimations were not made, and the absence of the data is acknowledged in the record.**File Format and Software Compatibility** The dataset is provided in CSV format for ease of use and compatibility with various data analysis tools. It can be opened and processed using software such as Microsoft Excel, R, or Python (with Pandas). Users can download the dataset and work with it in software such as R (https://cran.r-project.org/) or Python (https://www.python.org/). The dataset is compatible with any software that supports CSV files.This dataset provides valuable information for research related to the geographical distribution and climate preferences of *Cycas taiwaniana* and can be used to inform conservation strategies, ecological studies, and climate change modeling.
