On protection of rare and endangered plants in Changbai mountains

Located in the southeast of Jilin Province, Changbai mountains are an important plant germplasm resources treasury in the Eurasia in the Northern Hemisphere, where many ancient endangered plants are conserved. A three-year research found out that there were 28 species of rare and endangered plants belonging to 19 families and 26 genera in Changbai mountains. There are 1 family of fungi belonging to 1 genus and 1 species, 2 families of fern belonging to 2 genera and 2 species, 3 families of gymnosperm belonging to 3 genera and 4 species, and 13 families of angiosperm belonging to 20 genera and 21 species.
