Abstract: Aims Dongtou National Marine Park (DNMP) is located on the southeast coast of China, belonging to the subtropical evergreen broad-leaved forest. However, we are still unclear about the vegetation types on most islands in DNMP. Therefore, we aimed to investigate the main vegetation types on islands in DNMP, which is expected to provide data support for vegetation research and vegetation restoration on ocean islands in eastern China. Methods We conducted vegetation survey by setting up sampling plots on the islands in DNMP. A total of 90 plots were set up on 16 islands in DNMP. We recorded the species composition and habitat in-formation in each plot and referred to the "Vegegraphy of China" for vegetation type classification and naming. Important findings A total of 3 Vegetation Formation Groups, 8 Vegetation Formations, 34 Alliances, and 80 Associations were found in DNMP. Pinus thunbergii Evergreen Needleleaf Forest, Casuarina equisetifolia Evergreen Broadleaf Forest, Acacia confuse Evergreen Broadleaf Forest, Eurya emarginata Evergreen Broadleaf Shrubland, and Eurya japonica Evergreen Broadleaf Shrubland were widely dis-tributed on islands.
