Long-term community baseline dataset from alpine grassland monitoring sites across different climatic zones in Xizang, China

Establishing a long-term baseline dataset based on permanent monitoring is therefore of great significance for revealing regional vegetation patterns, assessing ecological change, and supporting long-term monitoring. In this study, we integrated the 2025 community survey data from long-term alpine grassland monitoring stations across different climatic zones in Xizang, China, to construct a baseline dataset of alpine grassland communities.

The dataset consists of four worksheets: site information, community survey data, diversity indices, and species list and distribution. It includes records from 15 sites, 140 species observation records, and 52 species in total. The community survey data include species names, cover, height, species richness, as well as community diversity indices calculated from the survey data, including the Shannon-Wiener index, Simpson index, and Pielou’s evenness index.
