Resource and conservation status of national key protected wild plants in Shaanxi Province,China
Based on the references of natural reserves in Shaanxi Province,field survey,and digitized herbarium specimens provided by China Virtual Herbarium(CVH),and List of National Key Protected wild Peauts(NKPWPs)(2021 Version),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 families,67 genera were distributed in Shaanxi Province,including 3 species in 1 genus of 1 family of lycophytes,6 species and 2 varieties in 6 genera of 2 families of gymnosperms,and 85 species,1 subspecies and 10 varieties in 60 genera of 35 families of angiosperms,representing 2.88%,6.73%and 90.38%of the total NKPWPs,respectively.(2)The number of the NKPWPs represented about 18.18%,5.09%,and 2%of families,genera and species of the total vascular plant in Shaanxi Province,respectively.(3)Among 104 species of NKPWPs,26 species listed in the last version(1999)had been protected,and 78 species were added newly,in which 24 species were ever listed and protected as local protected wild plants,and a total of 54 additional species were not protected at all before,accounting for 52%of the total NKPWPs,e.g.Phalaenopsis zhejiangensis,Dendrobium flexicaule and Paeonia rockii.The endangered status analysis showed that 5 species were critically endangered(CR),representing 4.81%,22 species were endangered(EN)and 22 species were vulnerable(VU),representing 24.04%of the total NKPWPs,respectively.(4)Qinling-Bashan region was a concentrated distribution area of NKPWPs,about 60 species were distributed in Zhenping County,accounting for 57.69%of the total,and 47 species were distributed in both Pingli County and Foping County;contrast to it,few species found in the north area of Shaanxi Province.(5)There were 249 reserves in Shaanxi Province,including the natural reserve(national and provincial),wetland parks and forest parks,and about 70 species representing 67.31%of NKPWPs had been effectively protected in these areas.We suggest:investigate the resources,distribution and status of the additional species of NKPWPs in Shaanxi Province,especially focus on the 54 species which are not protected previously;facilitate the regional botanical gardens in the Loess Plateau area of Shaanxi Province;dynamic monitor and update data of NKPWPs in natural reserves,so as to provide a scientific and valuable reference for in situ and ex situ conservation in the future.
