Summary.<\/b><\/p>\n

In the North of our country there are many fresh water reservoirs tens of thousands in areas such as Hoa Binh hydro-electric lake 21,000 ha, Ke Go lake (Ha Tinh; 2,806 ha), Cam Son Lake (Bac Giang; 2,600 ha), Nui Coc lake (Thai Nguyen; 1,000 ha), Thac Ba lake (Yen Bai; 23,400 ha)\u2026.<\/p>\n

As there are in our country two seasons: rainy season (usually from April to October) and dry season (from November to March the next year), water in the lake fluctuates with season resulting in seasonal water submersion in some areas adjacent to the lake, those are semi-water submersion land.<\/p>\n

The research on forest planting in semi-water submersion areas adjacent to the lakes is just now initially mentioned. The Forest Science and Techniques Application is carrying out the research subject \u2018Establishment of Forest planting models in semi-water submersion areas adjacent to water reservoirs in North Vietnam, 2002 \u2013 2006″.<\/p>\n

Initial results of establishing forest planting models in semi-water submersion areas adjacent to Ke Go, Thac Ba, Cam Son lakes affirm the success of forest planting in semi-water submersion areas.<\/p>\n","protected":false},"excerpt":{"rendered":"
