Working with Baijitan Tree Farm, we continued our desert control effort in 2017. The reforestation site is located at Daliumaozi sand area, Baijitan Nature Reserve, Lingwu, Ningxia. Over 200,000 shrubs have been planted, covering a total area of 66.7 hectares. The major kind of what we planted in the site is Caragana, and a number of Calligonum were also planted. But this small number of Calligonum were supposed to be pioneer species. We collect data only about Caragana. In year 2018, the total survival rate of Caragana in 2017-NX forest site is 55.25%. The average height is 88.12cm and average radius is 24.23cm. Forest's planting density is 6,240 shrubs per hectare, and the survival density is 3,435 shrubs per hectare. These results have far exceeded our planting goal, which was 2,700 shrubs per hectare.
The ecological investigation shows that the vegetation coverage is 19.21%. In vegetation structure, herbage layer is dominant, and shrub layer is gradually growing. 10 kinds of the herbal plants are founded in the site, which is increasing compared to last year. Agriophyllum squarrosum is still the one that’s mostly found.
