2019年，MTP项目与内蒙古通辽市科尔沁左翼后旗林业局合作，在1个沙荒地进行了生态修复，林地东侧为高速公路，北侧为高速公路辅路，造林树种包括樟子松、五角枫、小叶锦鸡儿等，其中主体造林以樟子松为主，间种少量五角枫，沙化严重的区域栽植小叶锦鸡儿。
Cooperating with the Forestry Bureau in Keerqinzuoyihou Qi, Tongliao in 2019, MTP contributed to the ecological restoration of one sandy land plot by planting a mix of Pinus sylvestris L. var. mongolica Litv. (scotch pines), Acer mono (maples) and caragana microphylla Lam. The main species is scotch pine, with few maples in-between. And caraganas were mostly planted in severe desertified area.

2019年林地立地条件较差，林地三面沿路，所以相对来说，其栽植和抚育的难度较低。2024年度进行了抽样测量，其整体保存率均值为60%。樟子松平均保活率为60%，五角枫和小叶锦鸡儿占比较低且分布零散，无法直接核算，不纳入调查。林地整体没有发生较大变化，保存率始终在60%左右浮动，林地保存状况相对稳定。而林地保存率偏低，主要源于样点之间数据的差异，如下图：
The site conditions were not good. The forest plot is surrounded by the roads on three sides, which makes it easier to plant and nurture the trees. According to the 2024 forest survey, the overall survival rate in 2024 was 60%. Scotch pines averaged 60% survival. Maples and caraganas accounted for a relatively low percentage and were scattered, so they could not be directly accounted for and were not included in the survey. The forest had not changed significantly, the survival rate had always fluctuated around 60%, and the surivival situation of the forest was relatively stable. The main reason for low survival rate was the differences in data between sample sites, as shown below:

可以看到，林地大部分区域的保存情况较好，个别区域保存情况不佳。由于林地内起伏较大，部分区域受地形限制，致栽植和抚育的难度较高，也就导致其保存率的偏低。
It can be seen that most areas of the forest are well preserved, with a few poorly areas. Due to the undulating nature of the forest, some areas are difficult to plant and nurture because of topographical constraints, which leads to low survival rates.
樟子松生长的情况相对健康，树高、胸径、地径等指标均有一定程度的上升。林地内树高大于1.3米（达到胸径测量指标高度）的比例由上一年度的47%上升至87.5%，其增幅较往年比较显著，说明林地苗木在增粗增高，逐渐进入快速生长期。
The growth of pines was relatively healthy, tree height, diameter at breast height, basal diameter and other indicators had risen to a certain extent. The percentage of trees above 1.3 meters was increasing from 47% to 87.5%. These data were more significant than previous years, indicating that the seedlings were thickening and increasing, and gradually entering the rapid growth period.

由于地势起伏过多，林地密度表现出较明显的差异，部分区域分布集中，部分区域分布零散。也造成不同区域的抚育质量差异，从而导致保存率的差异。从夏季走访看，林地内樟子松生长情况良好，同时林地内的柠条生长也非常迅速。林地内的植被恢复情况也较好，沙土裸露的情况很少，基本受到控制。生态恢复的成果明显。
Due to the rugged terrain, the density of forest varies, with concentrated distribution in some areas and scattered distribution in other areas. It also caused differences in maintenance in different areas, which led to differences in survival rate. From the summer visits, there was good growth of pines within the forest, and the caraganas grew also very rapidly. Vegetation restoration in the forest was also good, with very little exposed sand, which was basically under control. The results of ecological restoration were obvious.

综上所述，林地保存情况变化不大，苗木整体保持生长，树高等指标增幅显著。没有发生大面积的家畜干扰，基本上没有发生明显的人为破坏。
The survival of the forest basically remained the same. The trees were kept growing and the increase of the growth index such as height was significant. There was no large-scale interference of grazing or any interference of human activities observed.
