Native and Endangered Timber Tree Species in Homegardens of Northeast and Northcentral Vietnam

Agro-biodiversity is the result of natural and human selection processes involving animal, plant, and micro-organisms in agricultural systems, and is important for determining the socioeconomic and ecological benefits that can be derived from the systems [1]. The trend of developing monoculture agricultural systems for the sake of high productivity and economic return, however, has led agro-biodiversity into alarming level [2]. Despite the global trend, homegarden can become an avenue for investigating on-farm plant genetic resources since they often serve as refuge for native plant species and act as experimental sites when introducing new species/varieties [3]. While the socioeconomic and ecological benefits of homegardens are relatively well known, nonetheless, more research is needed to understand their contributions to agro-biodiversity and in-situ conservation [4,5].
