China contributes case studies from more than 19 major conservation areas, covering forests, mountains, coastal zones, and tropical regions. These sites span a wide range of ecological and climatic gradients and provide an excellent testbed for integrated biodiversity and climate monitoring approaches. The Chinese case studies include protected areas, ecological restoration zones, mountainous forest systems, coastal and wetland environments, as well as subtropical and tropical ecosystems. They enable the application of Essential Biodiversity Variables (EBVs) and Essential Climate Variables (ECVs) across diverse landscapes and support the development of harmonised monitoring methodologies between the EU and China. Through the integration of satellite Earth observation, in-situ environmental data, and AI-driven analytical models, these case studies help assess habitat change, ecological connectivity, species distribution patterns, and the impacts of climate change on vulnerable ecosystems. At the same time, they provide real-world environments to test nature-based solutions, ecological restoration practices, and policy-relevant monitoring frameworks that can be scaled from local conservation areas to national and international biodiversity and climate strategies.
