2018年，MTP项目与内蒙古通辽市科尔沁左翼后旗林业局合作，在3个沙荒地进行了生态修复，造林树种包括樟子松、五角枫、柳树、黄菠萝、小叶锦鸡儿等，其中主体造林以樟子松为主，道路防风带以五角枫等为主，内部沙化区域栽植了部分小叶锦鸡儿。
In 2018, cooperating with the Forestry Bureau in Keerqinzuoyihou Qi, Tongliao, MTP contributed to the ecological restoration in three plots of sandy land by planting a mix of Pinus sylvestris L. var. mongolica Litv. (scotch pines), Acer mono (maples), willows, phellodendron amurens and caragana microphylla Lam. The main species is scotch pine. Maple trees were planted as the windbreak. While caragana were planted in some part of the desertified areas.

2018年林地立地条件较差，部分区域沿路，所以栽植和抚育难度较低、质量较好。2018年三块林地（2018-1，2018-2，2018-3）在2024年度的总体保存率为81.35%。从上图看，三块林地的保存率变化不大，林地保存情况良好。
The 2018 Forest's terrain conditions are not good. The site is beside the roads on some sides, making it easier to carry out the planting and maintenance work. The overall survival rate of three forest plots(Plot 2018-1, 2018-2 and 2018-3) in 2024 was 81.35%, and we could found from the above graph that the survival rates of the three plots were good and not changed too much.
该林地采用的是大苗木低密度模式栽植，树高、地径、胸径等指标均值都较高。下列图为三块林地以上数据的变化图，可以看到树高均值增幅显著，地径均值和胸径均值的变化和树高类似，在本年度的继续增大，增长幅度也较显著。树高大于1.3米的比例也大幅度上升。
The forest was planted with high-density large seedlings and the average height, basal diameter and diameter at breast height(DBH) were all rather high. The changes of these indicators are shown in the below graph. It shows that the average tree height was increasing significantly. The changes of average basal diameter and DBH were like the tree height, continuing to rise this year and the growth speed was obvious. The percentage of trees above 1.3 meters was also increasing significantly.

总的来看，2018林地逐步进入快速生长期，林地保存率相对往年较稳定，同时树高、地径、胸径等指标的增幅显著，林地生长相对健康。2018-3林地具体生长数据如下：
Overall, the 2018 Forest gradually entered a rapid growth period, with relatively stable survival rates compared to previous years, along with significant increases in tree height, basal diameter, DBH, and other indicators of relatively healthy forest growth. The growth data of Plot 2018-3 is presented below:

林地情况说明 Forest Description
林地内原有杨树生长茂盛，松树的树行相对完整，部分区域的松树生长非常茂盛，内部出现大量灌木丛，地面覆盖的程度较高，直接裸露地表的区域较少。林地整体上生长较健康稳定。
The forest had a high level of poplar growth, relatively intact pine rows, some areas of very lush pine growth, a large amount of internal undergrowth, and a high level of ground cover, with fewer areas of direct surface exposure. The forest was generally healthy and stable.
