According the  results of the plant species for essential oil in Sop Cop Nature Reserve  Area have identified 228 species, 158 genus of 66 families belong Pinophyta and Magnoliophyta. The diversity of essential oils plants fully expressed in 5 life forms with the spectrum of life forms is: SB = 59,65Ph + 13,59 Th + 11,40Cr + 7,89 Ch + 7,44Hm. In addition to the value for essential oils, the species also give other uses such as medicine with 228 species, edible with 64 species, timber with 62 species, making wine yeast with 27 species, spices with 25 species, making bonsai 9 species, making flavor 5 species, 3 species of oil, and lowest with 2 species having poisonous. We have been identified 16 species of plants (accounting for 7.02%) as being endangered in Vietnam Red Book (2007) and 1 species in red list of IUCN (2017). These are species with a small number of individuals that need to have policies for conservation and development
