 Grasslands cover 41.7% of China's total land area and are home to over 20 million people. However, grassland fires occur annually, causing significant damage. To better understand these fires, we examined the spatiotemporal patterns and climate drivers in China from 2008 to 2020. We found that most fires occurred in Inner Mongolia, with the majority occurring in the Hulu and Buye and Zilingor grasslands. Northern China experiences a major fire season in April due to strong winds and drought, while fires in southern China appear to be less influenced by climatic factors. Our findings provide valuable information for fire prevention and management authorities in China. This article was authored by Zhu Wang, Aiyu Wang, Chichao Yao, and others.
