                 Abstract: Based on the references of natural reserves in Shaanxi Provinceꎬ field surveyꎬ and digitized herbarium
                 specimens provided by China Virtual Herbarium (CVH)ꎬ and List of National Key Protected wild Peauts (NKPWPs)
                 (2021 Version)ꎬ and List of National Key Protected Wild Plants distributed in Shaanxi Province. The resource and
                 conservation status of species NKPWPs distributed in Shaanxi Province was investigated and analyzed in present
                 study. The results were as follows: (1) A total of 104 species ( including subspecies and variety) belonged to 38
                 familiesꎬ 67 genera were distributed in Shaanxi Provinceꎬ including 3 species in 1 genus of 1 family of lycophytesꎬ 6
                 species and 2 varieties in 6 genera of 2 families of gymnospermsꎬ and 85 speciesꎬ 1 subspecies and 10 varieties in 60
                 genera of 35 families of angiospermsꎬ representing 2.88%ꎬ 6.73% and 90.38% of the total NKPWPsꎬ respectively. (2)
                 The number of the NKPWPs represented about 18.18%ꎬ 5.09%ꎬ and 2% of familiesꎬ genera and species of the total
                 vascular plant in Shaanxi Provinceꎬ respectively. (3) Among 104 species of NKPWPsꎬ 26 species listed in the last
                 version (1999) had been protectedꎬ and 78 species were added newlyꎬ in which 24 species were ever listed and
                 protected as local protected wild plantsꎬ and a total of 54 additional species were not protected at all beforeꎬ accounting
                 for 52% of the total NKPWPsꎬ e. g. Phalaenopsis zhejiangensisꎬ Dendrobium flexicaule and Paeonia rockii. The
                 endangered status analysis showed that 5 species were critically endangered (CR)ꎬ representing 4.81%ꎬ 22 species were
                 endangered (EN) and 22 species were vulnerable (VU)ꎬ representing 24.04% of the total NKPWPsꎬ respectively. (4)
                 Qinling ̄Bashan region was a concentrated distribution area of NKPWPsꎬ about 60 species were distributed in Zhenping
                 Countyꎬ accounting for 57.69% of the totalꎬ and 47 species were distributed in both Pingli County and Foping Countyꎻ
                 contrast to itꎬ few species found in the north area of Shaanxi Province. (5) There were 249 reserves in Shaanxi
                 Provinceꎬ including the natural reserve (national and provincial)ꎬ wetland parks and forest parksꎬ and about 70 species
                 representing 67.31% of NKPWPs had been effectively protected in these areas. We suggest: investigate the resourcesꎬ
                 distribution and status of the additional species of NKPWPs in Shaanxi Provinceꎬ especially focus on the 54 species
                 which are not protected previouslyꎻ facilitate the regional botanical gardens in the Loess Plateau area of Shaanxi
                 Provinceꎻ dynamic monitor and update data of NKPWPs in natural reservesꎬ so as to provide a scientific and valuable
                 reference for in situ and ex situ conservation in the future.
