Thung Rech vegetation covers on limestone and caster valley in high area at commune Tu Son, Kim Boi district, Hoa Binh province. To apply research traditional methods, such as principle structured forms - Ecology of UNESCO - 1973, Wittaker’s principle of component structure of the plant species (in 1962) and review ecosystems (Tansley, 1935) have been rated the resource of rich flora with 656 species belonging to 406 genus and 138 families of 5 phylum vascular of plant are Psilotophyta, Lycopodiophyta, Polypodiophyta, Pinophyta and Magnoliophyta.

Also, the ecosystem of the plant contains the vegetation communities’ specific to limestone northern Vietnam, it plays an important role in environmental protection, disaster reduction, balance, regulation of the flow and climate as well as the biodiversity conservation of the area. To need to build up the legal system and scientific measures to conserve the plant resources of this kind.
