Supported by 12 forest sponsors, the Million Tree Project continued its desert control efforts in cooperation with Baijitan Tree Farm in 2020. Another 140,000 shrubs have been planted, covering a total area of 46.7hectares in Baijitan Nature Reserve.

According to local climate condition and hydrologic regime, we choose to plant a mix of shrubs and grass on the straw girds constructed to control sand movements. In every forest site, we need to plant four times to make sure at least 180 shrubs survived per Mu.
We have finished the construction of straw grids before the end of November, and sown seeds of Caragana Korshinskii Kom and Hedysarum scoparium in the straw grids during the raining season. The planting density is two meters by one meter, which means 200 to 300 grids per Mu have been sown seeds in. In addition, 1kg Artemisia ordosica seeds have been broadcasted per Mu. One worker can do about 300 squares per day. It took approximately 35 days for 40 works to finish the work.

From August 15th to August 25th, 10 volunteers joined this year’s summer forest survey and tree planting activities. The forest survey includes growth index, vegetation coverage and biodiversity. And the tree planting activities include constructing the straw grids, sowing grass seeds in the sandy land. They also visited the desert and the nature reserve’s museum to learn about the history and achievements of sand control in Lingwu and nationwide.
