                 Abstract: To systematically understand thebasic status of national key protected wild plants in Liaoning Province and to
                 support local biodiversity conservation decision ̄makingꎬ based on the List of National Key Protected Wild Plants (2021
                 edition)ꎬ integrating specimen records and field survey data from Liaoning Provinceꎬ a comprehensive analysis covering
                 species compositionꎬ geographical distributionꎬ endangerment levelsꎬ threat factorsꎬ and protection status were
                 conducted. County ̄level spatial autocorrelation and hotspot analysis methods were used to explore distribution clustering
                 patterns. Threat types were classified by combining internal and external factorsꎬ and classification conservation strategies
                 were put forward. The results were as follows: (1) There were a total of 32 types of nationally protected wild plants
                 distributed in Liaoning Provinceꎬ belonging to 21 families and 26 generaꎬ with Orchidaceae and Liliaceae as the
                 dominant families. (2) The distribution exhibited a distinct spatial patternꎬ with high species richness and aggregation in
                 the southeastern region (notably Fengcheng and Kuandian)ꎬ and sparse distribution in the northwest. (3) 90.63% of
                 these species had been effectively protected in situ within nature reserves. (4) These protected plants faced complex
                 threatsꎬ including habitat degradationꎬ overharvestingꎬ climate changeꎬ ecological competitionꎬ and population
                 ecological vulnerability. The conclusions are as follows: (1) National key protected wild plants in Liaoning exhibit
                 typical boundary distribution characteristicsꎬ and greater attention should be paid to edge populations in conservation
                 area planning. (2) Threats arise from interactions between internal and external factorsꎬ and conservation measures
                 should be stratified and classified accordingly based on threat types and protection conditions. (3) It is recommended to
                 establish an integrated conservation framework that includes intelligent monitoringꎬ ex situ conservationꎬ legal and policy
                 supportꎬ and public engagement. These findings provide a scientific basis for biodiversity management and policy ̄making
                 in Liaoning Province.
