Abstract

The mixed forest gardening model combining forestry and medicinal plants has been proven to bring dual benefits for forest growers, disaster prevention, contributing to social security and protecting the ecological environment. In this paper, a 3-hectare mixed gardening model including Tram Den and De van combined with medicinal plants Che hoa vang had been implemented in Ban Chan village, Dong Phuc commune, Ba Be district, Bac Kan province with the participation of 10 local households. After 2.5 years of planting, all three plant species grew well: the survival rate of Tram Den reached 95.30%; De van reached 95.15% and Che hoa vang reached 90.52%. The participating households have had initial income from harvesting leaves of Che hoa vang plants after 2.5 years of implementing the model. This mixed forest gardening model also showed the ability to reduce soil erosion comparing to the non-model area (reduced by 11.99% in 2021 and 6.99% in 2022). This is the first mixed forest gardening model including Tram Den + De van + Che hoa vang deployed in Vietnam. With this result, the model can be replicated in the areas around Ba Be Lake, creating multi-purpose forest gardens, which both of providing a livelihoods and reducing erosion, avoiding accretion of Ba Be lake and maintaining a sustainable forest ecosystem.
