# Spatial Distribution Dataset of All Constructive Grass Species in Tibetan Grasslands under 2024 and 2060

## TL;DR

This study creates a dataset showing where 44 important grass species will grow in Tibetan grasslands now and in 2060, helping manage ecosystems under climate change.

## Contribution

A novel spatial distribution dataset of 44 constructive grass species in Tibetan grasslands under current and future climate scenarios.

## Key findings

- The dataset includes habitat distribution changes like expansion, contraction, and stability for each species.
- It supports climate impact assessments, grassland-type projections, and ecosystem evaluations.
- The dataset aids in high-altitude grassland management and biodiversity conservation.

## Abstract

The Tibetan grassland is the principal ecosystem in a high-altitude, ecologically fragile region, providing vital services for biodiversity and local livelihoods. Constructive grass species play a pivotal role in maintaining the structure and function of grassland ecosystems. In this study, we constructed a comprehensive dataset of the spatial distribution of all constructive grass species (44) in Tibetan grasslands under current (2024) and four future (2060) climate scenarios by leveraging species distribution models and high-resolution ecological data. Our dataset encompasses each individual constructive grass species habitat distribution, including expansion, contraction, and stability. This dataset will be applied to climate-change impact assessment on individual species, grassland-type shift projection, and multi-stressor ecosystem-dynamics evaluation. It is essential for supporting grassland management, biodiversity conservation, and livestock production in high-altitude grassland ecosystems.
