Abstract: In order to understand the resource situation of trees, shrubs, and herbaceous plants in the single leaf grass forest of Wolong Nature Reserve, a survey was conducted through preliminary visits and later sample plots to understand the resource situation of trees, shrubs, and herbaceous plants in the single leaf grass forest of Wolong Nature Reserve. This survey found that there were 4 species of trees, 10 species of shrubs, and 33 species of herbaceous plants in the single leaf grass forest. The species and their families were studied, and their dominant subjects were analyzed. The research results would provide basic information and scientific basis for the protection and utilization of endangered single leaf grass resources.
