The occurrence data of wild apple in the Mountains of Central Asia Biodiversity Hotspot

To obtain high-quality occurrence records for wild apple across its whole distribution range, we compiled data from field surveys, herbariums and the literature. The field surveys were conducted in all of the countries with wild apple distribution in Central Asia. Precisely, we had several exhaustive investigations of wild apple populations in Xinjiang, China from 2008 to 2021, including distribution range and abundance of wild apple across its whole elevational ranges in six counties. For herbarium data, we combined the records from Global Biodiversity Information Facility and Chinese Virtual Herbarium. Finally, we obtained 8344 occurrence records for wild apple.

为获取野生苹果在整个分布区内的高质量物种出现记录（occurrence records），我们整合了野外调查、标本馆及文献三类数据。本次野外调查覆盖了中亚所有分布有野生苹果的国家；具体而言，我们于2008年至2021年间在中国新疆开展了多轮全面的野生苹果种群调查，涵盖6个县域内野生苹果在全部海拔梯度上的分布范围与种群丰度。在标本馆数据方面，我们整合了来自全球生物多样性信息设施（Global Biodiversity Information Facility）与中国数字植物标本馆（Chinese Virtual Herbarium）的记录。最终我们共获取到8344条野生苹果物种出现记录。
