According to the Việt Nam vegetation classification system, the Du Già NP has five main forest vegetation types: low mountain tropical moist evergreen close forest in mountains of less than 700m; medium high mountain tropical moist evergreen close forest distributed at latitude of more than 700m; limestone tropical moist evergreen close forest; secondary vegetation types including secondary forests that were rehabilitated after exploitation and farming; some supporting vegetation such as bamboo forests, plantations (pine, acacia) and shrubs, timber trees…
The flora system of the NP has 1,061 vascular plant species, belonging to 629 genus, 202 families and six phyla. In other words, out of seven vegetation phyla identified to be distributed in Việt Nam, the Du Già NP has six phyla, making up 85.71% of the phyla. The most diverse phylum is Magnoliophyta with 950 species (contributing 89.54%), followed by Polypodiophyta with 88 species (accounting for 8.29%), Pinophyta with 12 species (making up 1.13%), Lycopodiophyta with nine species (0.85%), the remaining belongs to Psilotales and Equisetophyta, each phylum has one species. In addition, the diversity is also shown in the number of identified families which is 202, making up 53.44% of the total families of the Việt Nam flora system, of which 29 families have high number of species (accounting for 56.08%) such as Orchidaceae with 65 species (6.13%); followed by Euphorbiaceae with 46 species (4.34%); Rubiaceae with 45 species (4.24%); Moraceae with 39 species (3.68%); Asteraceae with 33 species (3.11%); Lauraceae with 26 species (2.45%); Fabaceae and Verbenaceae with 25 species each (2.36%); Araceae with 22 species (2.07%); Rutaceae with 17 species (1.60%) and followed by the remaining 19 families.

Potential for ecotourism development
With cool climate and magnificent mountain landscape, there are potentials for tourism routes and spots and rest stops for tourists to view rare flora species, ancient trees, and wild fauna species in the NP. The NP has Ba Tiên mountain range with 25 small and large peaks and Đèo Gió area located in the provincial road No.176 located in Yên Minh district, has the potential for ecotourism and adventure tourism.
In addition to magnificent natural landscape and biodiversity, the Mông, Dao, Tày... people communities also maintain traditional cultural beauty such as: Cap sac festival, new rice praying festival, season praying festival, Gau Tao festival, dancing new year, fair, love market… In this area, tourists can see the colours of brocade costumes and the echo of gong and dances.
