The Adult Adansonia digitata L. (baobab tree) distribution map derived from very high resolution satelite imagery for 2010s across the Sahel at 1km resolution

The baobab tree (Adansonia digitata L.) is an integral part of rural livelihoods throughout the African continent. However, the combined effects of climate change and increasing global demand for baobab products are currently exerting pressure on the sustainable utilization of these resources. Here we employ sub-meter resolution satellite imagery to identify nearly 3 million baobab trees in the Sahel, a dryland region of 1.5 million km2. This achievement is considered an essential step towards improving valuable woody species' management and monitoring system. The map's overall underestimate bias is 0.27. To prevent mismanagement of this specific tree species, we aggregated every single adult baobab tree map to 1 × 1 km grids. We also classified the baobab trees using the tree crown diameters( small: 3-9m; medium 9m-13m; large: >13m). The baobab tree count map is also available for these three different size classes.

猴面包树（Adansonia digitata L.）是整个非洲大陆农村生计不可或缺的组成部分。然而，气候变化与全球对猴面包树产品日益增长的需求共同作用，正给这些资源的可持续利用带来压力。本研究借助亚米级分辨率卫星影像，在面积达150万平方千米的干旱地区萨赫勒（Sahel）区域识别出近300万株猴面包树。这一成果被视为完善珍贵木本物种管理与监测体系的关键一步。该图谱的整体低估偏差为0.27。为避免该特定树种的管理失当，我们将所有成年猴面包树的分布图谱聚合为1×1千米的网格单元。本研究同时以树冠直径为依据对猴面包树进行分级：小型（3-9米）、中型（9米-13米）、大型（>13米）。针对这三个尺寸等级，本研究亦提供了对应的猴面包树数量图谱。
