Socio-Ecological Effects on the Patterns of Non-native Plant Distributions on Hainan Island

Non-native plants spread to recipient areas via natural or human-mediated modes of dispersal, and, if the non-native species are invasive, introduction potentially causes impacts on native and local ecosystems as well economic losses. Therefore, we studied diversity distributional patterns plant in tropical island province Hainan, China its relationships with environmental socioeconomic factors by generating a checklist subsequently performing an analysis phylogenetic diversity. To generate checklist, began available, relevant literature representing 19 administrative units Hainan determined casual, naturalized, invasive status each conducting field surveys within 14 units. We found that comprise 77 casual species, 42 naturalized 63 species. Moreover, had diverse origins from North South America, Africa, Asia most common across belong families Asteraceae Fabaceae. numbers distributed bording coast arer greater than those interior province. Among coastal areas, Haikou has highest richness simultaneously, values for significantly, positively correlated predictor variables, population GDP (R 2 = 0.60, P < 0.01; R 0.64, 0.01, respectively). In contrast, landlocked Tunchang Ding’an have smallest number while their populations less quarter one tenth. strongest correlation minimum temperature coldest month, which predicts smaller Additionally, primarily urban rural built-up agricultural areas; dominated human activities. Overall, our study provides working theoretical framework reference control
