Species occurrence locations and environmental parameters used for predicting the potential planting regions of Pterocarpus santalinus

This study explores the habitat distribution of Pterocarpus santalinus, a valuable rosewood species, across China, focusing on its response to current and future climate changes. Utilizing the MaxEnt model, we assess its suitable habitat under present conditions and future climate scenarios (SSPs126, SSPs245, and SSPs585). Our findings reveal that the current suitable habitat, spanning approximately 409,600 km², is primarily located in the central and southern parts of Guangdong, Guangxi, Fujian, Yunnan, as well as in the Hainan provinces, along with the coastal regions of Taiwan, and the Sichuan-Chongqing border. The habitat's distribution is significantly influenced by climatic factors such as temperature seasonality (bio4), mean temperature of the wettest quarter (bio8), annual mean temperature (bio1), and annual precipitation (bio12), while terrain and soil factors play a lesser role. Under future climate scenarios, the suitable habitat for P. santalinus is projected to expand, with..., We identified the occurrence locations of P. santalinus using a three-pronged approach: (1) A comprehensive review of relevant literature; (2) Extensive field investigations; and (3) Data acquisition from online databases, specifically the Global Biodiversity Information Facility (GBIF, https://www.gbif.org) and the National Specimen Information Infrastructure (NSII, http://www.nsii.org.cn/2017/home.php). 
We downloaded environmental parameters from WorldClim (https://www.worldclim.org/data/index.html) and Harmonized World Soil Database v 1.2 (HWSD; http://www.fao.org/soils-portal/soil-survey/soil-maps-and-databases/harmonized-world-soil-database-v12/en/), processed them using ArcGIS 10.2, , # Species occurrence locations and environmental parameters used for predicting the potential planting regions of Pterocarpus santalinus

## Overview

The supplementary dataset is an integral component of our research paper, encompassing species occurrence records and associated environmental variables utilized for predicting potential species distributions. All environmental factors are stored in the ASC file format for ease of processing and analysis. To ensure the accuracy and interpretability of the data, we have also provided XML and PRJ files as supplementary materials. These additional files contain essential metadata and spatial reference system information, which are crucial for ecologists and conservation biologists when conducting predictive analyses for the potential distribution of other species.
