2014年度，MTP项目与内蒙古通辽市巴胡塔苏木的召根嘎查和边界嘎查合作，以杂交杨树为主，辅以封育措施对两个村的3块沙荒地进行了生态修复。
Hybrid poplars were planted on three sandy plots, in cooperation with Zhaogen Gacha (village) and Bianjie Gacha in Bahuta Sumu in 2014. The afforestation and enclosure work took place on the three sandy lands of two villages to restore the degraded land.

经调查核算，项目共造林3860亩，杨树343540棵，围栏约20200米，在2024年度，三块林地地整体存活率为68%。其中，2014-2的保存率为53%，其保存率年际变化及其与另外两块林地的对比如下图。三块林地的保存情况在2024年度出现较明显上升，2014-2和2014-3林地内于2021-2022年开展了高压电工程建设，为此进行了一定程度的补偿性栽植，补足了一部分苗木的损失，使保存率显著提升。
According to the forest survey, the total afforestation area of the project is 257.33 hectares, with 343,540 poplar trees and 20,200 meters of fences. The overall survival rate of three forest plots was 68%. Among them, Plot 2014-2 was 53%. The changes in the annual survival rates and the comparison with two other plots were shown in the below chart. The three plots showed a significant increase in survival rate in 2024. The Plot 2014-2 and 2014-3 had a significant increase in survival rate, because thecompensatory replanting to replenish some of the seedling loss due to the construction of high voltage power projects during the 2021-2022 period.

2014-1的林地状况较好，树高数值在5.5米及以上高度分布较多，林地整体生长情况健康；2014-2的树高集中于3米以下区域，灌木化特征明显；2014-3树高则相对集中于3-6米之间，灌木化不显著，但生长速度偏慢，林地整体生长情况相对健康，但需要继续观测。
The Plot 2014-1 was in good condition, with many trees as high as 5.5 meters or more, indicating that the overall growth was healthy. The tree heights in Plot 2014-2 had a concentration below 3 meters, with obvious shrubbing signs. The tree heights in Plot 2014-3 relatively concentrated between 3-6 meters, no shrubbings, but at a slower growth rate. The overall growth of Plot 2014-3 was healthy. Further monitoring is needed.

地径、胸径变化情况基本相同，随着林木的生长，均值不断增加。胸径的测量的位置在树干1.3米高度处。胸径可测量比例持续增长，表明林地还在持续生长，但比例绝对值偏低，其中2014-2的灌木化情况较明显。
Changes in basal diameter and diameter at breast height (DBH) were essentially the same. They were increasing as the trees grew. The DBH was measured at a height of 1.3 m from the trunk. The percentage of measurable DBH continued to increase, indicating that trees were keeping growing. The absolute value was considered rather low. The shrubbing stuation was striking in Plot 2014-2.

从走访看，林地内杨树的生长情况一般，底部杂枝茂密，灌木化的情况显著。林地内的杨树存在大量缺损，区域间也存在显著差异。林地内放牧情况较多。地势较复杂，积水情况反而较少，地表植被以沙生植物为主，大面积裸露的情况较少。
During the forest visit, the poplar growth was average, with dense overgrown branches on the ground and significant shrubbing signs. There were loss of trees within the forest and significant differences among different locations. A lot of grazing was found in the forest. The terrain was complex, so less ponding. The surface vegetation was dominated by desert plants, and there was not much bare ground.
