Abstract

Background & Aims: Focused on the predominant vegetation types in North China and the Qinghai-Tibetan Plateau, namely steppe and desert, this study delves into the unique and abundant biodiversity resources within these regions. The Steppe and Desert Plants Diversity Observation Network is one of the ten branches of the China Biodiversity Observation and Research Network. It endeavors to create permanent plots representing specific plant communities in areas with distinct vegetation alliances. Its objective is to conduct long-term monitoring of plant diversity dynamics at regular intervals

Progress: Over the past five years, the Steppe and Desert Plants Diversity Observation Network has achieved significant milestones in monitoring plant diversity within steppe and desert ecosystems. This paper presents an overview of the plan and construction progress, encompassing aspects such as the layout of monitoring sites, plot arrangement, monitoring indicators, and data generation.

Prospects: Looking ahead, the Steppe and Desert Plants Diversity Observation Network envisions advancements in three key areas: refining the spatial layout of monitoring sites, constructing an automated monitoring system and conducting research on the dynamics of plant diversity. These initiatives aim to comprehensively elevate the research standards and scientific service capabilities of steppe and desert biodiversity science in China. Additionally, they will furnish essential data support for biodiversity research and conservation efforts.
