Assisted natural regeneration approach was experimented in the Sahel region in the aim of restoring land and vegetation in accordance with the global objectives of the Great Green Wall for the Sahara and the Sahel Initiative. Two sites (Endé and Soula Kanda) located in the district of Bankass in the centre of Mali were concerned by this study. Assisted shoots and non-assisted shoots of Guiera senegalensis J. F. Gmel. were compared at Soula Kanda, while at Endé, only assisted shoots were monitored so that to assess the impact of this approach on the survival and the growth of the shoots of this species. The height, the diameter at the basis and the diameter at 1.30 m above the ground were measured from 2015 to 2017 at Endé and from 2016 to 2017 at Soula Kanda in November/December each year. For each treatment, thirty shoots were monitored and data were analysed using the software SYSTAT9 FOR WINDOWS. At Endé, the survival rate was 93%. At Soula Kanda, the survival rate of assisted shoots was 97% against 73% for the control. At Endé as well as at Soula Kanda, dead shoots were cut by farmers. The current annual increments at Endé were 44 cm year−1 for height and 1.27 cm year−1 for the diameter at 1.30 m above the ground. At Soula Kanda, the current annual increment for height was the same for the two treatments (20 cm year−1).

使用辅助自然更新方法 (ANRA) 恢复植被和退化土地：西非马里市中心 Bankass 的案例研究

在萨赫勒地区试验了辅助自然更新方法，目的是根据撒哈拉绿色长城和萨赫勒倡议的全球目标恢复土地和植被。本研究关注位于马里中心 Bankass 区的两个地点（Endé 和 Soula Kanda）。Guiera senegalensis JF Gmel 的辅助芽和非辅助芽。在 Soula Kanda 进行了比较，而在 Endé，只监测辅助芽，以便评估这种方法对这个物种的芽的存活和生长的影响。2015 年至 2017 年在 Endé 和 2016 年至 2017 年在每年 11 月/12 月在 Soula Kanda 测量高度、基础直径和距地面 1.30 m 处的直径。对于每次治疗，监测 30 个芽并使用软件 SYSTAT9 FOR WINDOWS 分析数据。在 Endé，存活率为 93%。在 Soula Kanda，辅助芽的存活率为 97%，而对照为 73%。在 Endé 和 Soula Kanda，农民们将枯枝剪掉。Endé 目前的年增量为 44 cm year−1 高度和 1.27 cm year−1 距离地面 1.30 m 处的直径。在 Soula Kanda，两种处理的当前年身高增长相同（20 cm 年-1）。距离地面 1.30 m 处的直径为 27 cm year−1。在 Soula Kanda，两种处理的当前年身高增长相同（20 cm 年-1）。距离地面 1.30 m 处的直径为 27 cm year−1。在 Soula Kanda，两种处理的当前年身高增长相同（20 cm 年-1）。
