AB  - Seedling regeneration is one of the key approaches to achieving ecological restoration and reconstruction, and it is also the foundation for maintaining forest dynamic stability and sustainable development. We collected a three-year monitoring dataset of 12,432 seedlings from the cold-temperate coniferous forests of the northern Qinghai-Tibet Plateau to assess the density constraints of seedlings of different sizes and the effects of abiotic factors with significant spatial heterogeneity on seedling regeneration. This dataset includes the 2022–2023 Qinghai spruce seedling survival and environmental factor dataset from the Qilian Mountain Forest Ecological Station. The data include seedling survival/mortality status (status), elevation (ELEV), slope (Slope), terrain position index (TPI), seedling neighbor density (Scon), tree neighbor density (Tcon), soil quality index (SQI), mean leaf angle (MLA), canopy gap fraction (CGF), and seedling height (Height).
