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屯开展，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。该林地位于东黑冠长臂猿栖息地中心。
In 2022, MTP collaborated with Guangxi Bangliang Gibbon National Nature Reserve and planted 544 trees in Dadu Tun. The tree species are Choerospondias axillaris and Ficus, microcarpa. The total area of trees planted is 0.55 hectares. The forest site is located in a key area of the habitat of Cao Vit Gibbon.
2023年2月，该林地进行除草抚育。2023年6月、10月工作人员两次走访该林地，并开展林地调查。抽样比例为13.8%，树木总存活率达72.72%。相比2022年度的77.46%有明显的下降情况，主要由于区域内南酸枣的死亡比例较高，由原本和小叶榕数量上的1：1，下降为小叶榕数量的1/3。其中南酸枣平均树高1.84米，小叶榕平均树高1.86米，较2022年有较大增长，符合当地生长的普遍情况。虽然南酸枣的存活情况较差，但存活下来的苗木生长速率却优于小叶榕。
In February 2023, the weeding work was carried out on the plot. The team visited the site in June and October again, and conducted the forest survey. The sampling ratio of trees was 13.8%, and the overall survival rate was 72.72%. There was a drop from the survival rate of 77.46% in 2022, which was casued by the death of a few Choerospondias axillaris in the site. The amounts of Choerospondias axillaris and Ficus microcarpa was even initailly, but now the Choerospondias axillaris left was one third of the Ficus microcarpa. The average height of Choerospondias axillaris and Ficus microcarpa was respectively 1.84 m and 1.86 m, which were higher than 2022. The growing speed is common for the trees in these areas. Comparing the two tree species, the survival rate of Choerospondias axillaris was worse than Ficus microcarpa, but the survived Choerospondias axillaris grew better than Ficus microcarpa.

在林地调查中发现林地中禾本科草本植物生长迅速，阻碍到树木生长，需进一步开展抚育工作。苗木的覆膜依旧存在，草丛下有大量动物活动的痕迹。在林地中央位置的榕树遭到严重的破坏。据判断应是竹鼠一类动物啃咬所致。
The grass was growing very fast on the site, blocking the growth of the trees. More weed control work is needed. The multch films on the bottom of the trees remained, but there were a lot traces of animal activities on the grassland. The Fig trees in the middle of the site were badly damaged. The wounds looked like caused by the rodents such as Rhizomys.

该林地进入道路复杂艰难，抚育难度很大。但处于三群长臂猿栖息地交界处，继续抚育工作和保证林地恢复效果十分重要。项目组将在2024年继续走访、调查和进一步开展林地抚育。
The forest site is very difficult to reach and thus making it also very difficult to carry out the maintenance work. But it’s in the overlapping area of the habitat for three gibbon family groups, so very essential to the Cao Vit Gibbon Conservation. The team will continue forest visits, survey and maintenance work in 2024.
