In an effort to offset carbon dioxide, Plot 2012-1,2012-2,2012-3 and 2012-4 were planted in cooperation with Liujiazi Tree Farm back in 2012. The survival rate of poplar is 91% and of pine is 64%, remains the same as last year. The growth of poplar is steady and the growth of the main indexes will continue. The proportion of trees with a height more than 1.3m is relatively high and basically stable. The situation of pines is steady and the growth has accelerated.
Generally speaking, the overall situation is stable. Poplars have too much branches towards bottom, but the growth situation is good. Pines retained uneven, most areas of woodland species quit, reduce the loss of new cases of pines, begin to grow steady.
