This study evaluated the ecological impact of the alien weed Ambrosia trifida on the vegetation of paddy banks in Korea. A. trifida was found in 28 sites out of 118, and interestingly, these sites were mainly in the country"s northern provinces (Gyeonggi-do and Gangwon-do). Echinochloa crus-galli was the most distributed species at the bank of rice fields in both the absence and presence of giant ragweed. According to our survey, 22 species of annual and four species of perennial weeds were found in the place where the A. trifida was also found, and 47 species of annual and seven species of perennial weeds were found where A. trifida did not exist. The average relative cover of A. trifida was 75.8%. The number of annual weed species per square meter showed a relatively significant difference of 3.36 in the presence of A. trifida and 7.18 in the absence of A. trifida. The number of perennial weed species per square meter also showed a significant difference of 0.43 in place with A. trifida and 1.39 in place without A. trifida . There was a negative correlation between the relative cover, relative density, and importance value of perennial weed species and A. trifida. Perennial plant species had lower relative cover, density, and importance value in the presence of A. trifida compared to its absence. The diversity index was 0.61 in the presence and 0.86 in the absence of A. trifida. From the above results, it was concluded that the growth of A. trifida had a negative ecological impact on the diversity of the surrounding plant species on the bank of the rice field.
