Biomass information and location of large old trees in Hainan Island (China)

This dataset contains detailed information on large old trees from Hainan Island, China, collected for the study "Diversity and abundance of large old trees in Hainan Island: Spatial analysis and environmental correlations." The dataset includes tree location, family, species, estimated age, height (in meters), diameter at breast height (DBH in centimeters), and average crown diameter (in meters). These data were gathered to analyze the spatial distribution and abundance of large old trees and explore their correlations with various environmental factors. The dataset provides a valuable resource for ecological studies focused on tree conservation, biodiversity, and the role of large old trees in tropical ecosystems.

Methods
This study combined field surveys with government data to analyze LOTs in Hainan. We consulted the "Announcement on the List of Old and Valuable Trees in Hainan Province" issued by The People's Government of Hainan Province. Hereinafter referred to as "the LOT-list", the document provides essential tree data of trees over 300 years old, such as serial number, geographical location, elevation, age, height, diameter at breast height (DBH), and crown size.
