2009年共有三块合作林地，合作方均为库伦旗先进苏木的先进林场。造林树种为杨树与文冠果。

In 2009, Poplars were planted on Plot 2009-3 and Yellow horns were planted on Plot 2009-1 and Plot 2009-2 in cooperation with the Forestry Bureau in Xianjin Sumu, Kulun Qi, Tongliao.

2009-3杨树的年度存活率为51%。2013年以后，杨树的地径和胸径两项指标都表现出稳定的增长趋势。

The survival rate of plot 2009-3 is 51%. The basal diameter and diameter at breast are both growing stably since 2013.

林地整体上看，逐渐稳定，但由于林地内区域分布不均衡，苗木间差异化较大，基本可以归入低效林。在未来被更新采伐的可能性较高，尤其是其中苗木分布较少的区域。

The forest has become gradually stable, but due to an uneven distribution of trees, the forest is less effective. In the future, the forest is likely to be felled and regenerated, especially in areas with fewer seedlings.
