2022年,百万植树计划和广西邦亮长臂猿国家级自然保护区合作在保护区大笃村弄曼开展,栽植544棵树,造林地总面积为8.25亩。种植树种为小叶榕和南酸枣混交。截止目前,已完成了全部造林工作和第一轮补植。根据7月的林地走访及测量,经过补植后存活率达到100%。后续百万植树计划也将通过加强抚育、浇水、除草等手段增加存活率。
In 2022, MTP collaborated with Guangxi Bangliang Gibbon National Nature Reserve and planted 544 trees in Nongman, Dadu Village. The total area of trees planted is 0.55 hectares. The trees planted were the mix of Ficus concinna and Choerospondias axillaris. To date, the planting work and first round of replanting work were completed. According to the forest survey in July, the survival rate of the trees after the replanting reached 100%. To ensure the survival of the trees, MTP will take the follow-up measures such as nursing the trees, watering and weeding.

由于种植的是截干苗,计算截干高度没有统计意义,因此我们统计了出芽高度以替代树高数据。小叶榕的出芽高度平均值是160.35cm,平均地径是5.88cm,平均胸径是3.35cm。南酸枣的出芽高度平均值是77.53cm,平均地径是5.16cm,平均胸径是4.66cm;只有21%的南酸枣植株有胸径数据。在补植前,南酸枣存活率仅为44%。推测主要原因是发芽点在树根处,无法与快速生长的草本竞争。第一轮补植全部采用了小叶榕苗。
The seedlings were stem cutting ones, so the tree height was not considered a significant indicator. We measured the height where the seedlings sprouted instead. The average budding height of Ficus concinna was 160.35 cm, and the average basal diameter was 5.88 cm, and the average Diameter at Breast Height (DBH) of Ficus concinna was 3.35 cm. For Choerospondias axillaris, the average budding height was 77.53 cm, the average basal diameter was 5.16 cm, and the average DBH was 4.66 cm. Only 21% of the Choerospondias axillaris seedlings were measurable on DBH. Before the replanting, the survival rate of Choerospondias axillaris was found to be 44%. The main reason was the seedlings were mainly sprouting on the bottom, and failed in the competition with the fast-growing plants on the ground. All the seedlings replanted were Ficus concinna.

邦亮保护区所属的黒冠长臂猿栖息地是亚热带原始森林,喀斯特地貌,气候湿润炎热。后期抚育计划是将注重除草松土并且适当施肥; 百万植树计划将继续监测该地块并进行适当的补植施肥。
The habitat of Cao Vit Gibbon at Bangliang Reserve is subtropical primary forest with Karst landscape, and the weather is humid and hot. The follow-up monitoring and nurturing plan was to take several rounds of weeding, loosening soil and fertilizing. MTP will keep visiting the forest site and continue the follow-up nurturing work for the trees.
