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