Green tree planting project

Before the establishment of Shizong Huahai, Shizong's local planting forest area was less than 100,000 mu, and the forest area continued to decrease. Since year 2007 Shizong Huahai was established, the company has actively encouraged local forest farmers' enthusiasm of planting, which actively promoted the development of plantation forests and related industries, and boosted 80,000 forest farmers. By the end of 2016, the scale of local planting forests reached 1 million mu, showing a rapid growth trend.

While planting forests bring economic benefits, ecological benefits are also significantly improved. The 1 million mu plantation forest absorbs about 24 million tons of carbon dioxide every year, and the environmental protection effect is remarkable.
