Plant community composition data during the early restoration stage of severely degraded alpine meadows

It serves as the core dataset for the paper titled "Plant community exhibits stochastic assembly pattern at early stage of vegetation restoration in heavily degraded alpine meadows on the Qinghai–Tibetan Plateau", published in the Journal of Plant Ecology.Sampling location: Maqin County, Guoluo Tibetan Autonomous Prefecture, Qinghai Province, China.Sampling period: Mid‑to‑late August, 2021–2023.In the dataset, row names denote treatment names, column names are the Latin names of plant species, and the data values represent the relative importance values of the plants.The dataset consists of three CSV files named as follows: 2021_Plant community.csv，2022_Plant community.csv，2023_Plant community.csv
