During the war, natural ecosystems of Gio Linh district were seriously impacted by military operations, especially using herbicides of the U.S. military. Consequently, over the decades, the vestiges have been occured in many ecosystems in the area. Thousand hectares of vacant land, grasslands and shrubs created after the war are still existed untill now but no answer. The anthropogenic ecosystems that formed after the impact of herbicides usually have simple structures, has not even reached a stable formation: secondary forest ecosystem, vegetation with unstable stories, many vines
the grassland ecosytem, the grassland and shrub with simple structure, mainly species compostion of hard and big stem grass. As vegetation succession, in current conditions, recover of the forest is entirely possible occurred in the transition zone between forest and grassland, but in very slow speed. The reason for this is because the destroyed ecosystems, are existing critical factors that forest vegetation is not likely to arise and exist. This is the reason why even though the war has finished in nearly 40 years, the vast area of Gio Linh district still exists grassland and shrub ecosystems. To be able to exploit, use and improve the large area of grassland, shrub formed after the war in Gio Linh, it needs appropriate technical measures
the first measure is upgrade the environmental conditions of the area.
