In Vietnam, shrub vegetation accounts for a very high proportion of forest land in the whole country. However, the study of biomass and carbon storage capacity of shrub vegetation type has not been properly considered. In Ha Giang province, there exist many types of shrub vegetation, which originated from slash and burn cultivation. However, these types of shrubs are not only different in terms of fallow periods, but also differ in their distribution over different height. Therefore, the baseline carbon pricing should be calculated for each subregion of the locality. This article presents results of research on carbon storage and carbon baseline building for shrub vegetation in Tung Ba commune, Vi Xuyen district, Ha Giang province (in valley and lowland subregion). This is the scientific data for a rational and sustainable use of shrubs.
