Mapping Potential Planting Areas for Golden Camellias in North Vietnam
Keywords:Active ingredient, Camellia L., Ethnic communities, Natural condition, Poverty reduction
This study mapped potential areas for planting golden camellias in Cao Bang province, North Vietnam. Natural conditions (elevation above sea level, annual precipitation, and annual air temperature), where 6 golden camellia species (Camellia impressinervis, C. kirinoi, C. megasepala, C. tuyenquangensis, C. hamyenensis, and C. tienii) naturally distribute, were used for mapping. Three map layers (topography, precipitation, and air temperature) were used. Each main condition was classified into 3 levels for planting, “not suitable”, “suitable”, and “very suitable”. The results indicated that 1,970 ha, accounting for 0.3 % of the total land area of Cao Bang province, was classified as “very suitable” for planting golden camellias. “Suitable” areas counted for 62.7 %, and “not suitable” areas accounted for 37 % of the total land area, respectively. Mapping suitable planting areas is the 1st step for the successful planting of any species. It is recommended that golden camellias should be first planted in very suitable areas, after which planting may be extended to some suitable areas.
