울산시 태화강 > PROJECT

Originating from the western forest region of Ulsan and flowing into the East Sea, this river includes a 644㎢ area designated as a National Garden in 2019, making it one of South Korea’s official national gardens—a region of high timeliness and ecological significance. While naturally growing reeds and silvergrass are used as landscape elements, the area struggles with the proliferation of invasive alien species such as Aster pilosus and Humulus japonicus within the habitat. In 2023, Ulsan City allocated approximately 61 million KRW and relied on volunteer activities to address the removal of these invasive species. A company like ours can achieve the same result at a reduced cost of 45.5 million KRW by utilizing adaptable native species, offering a 30% cost reduction.
