The expansion of Mount Halimun Salak National Park (TNGHS) from Mount Halimun National Park (TNGH) formed the Halimun Salak Corridor (KHS). This corridor area functions as a habitat and movement path for important and protected animals, especially the javan gibbon. The current condition of KHS is fragmented and degraded by anthropogenic activities. This can disrupt canopy connectivity and the emergence of invasive alien species occupying fragmented areas. This study aims to determine canopy connectivity based on vegetation structure and determine the potential for invasive alien plants based on vegetation composition. The research was conducted in Halimun Salak Corridor zone 3B by dividing it into 3 lanes. The method used is vegetation analysis with a combination of multilevel square plots and using SExI-FS software to describe tree profile diagrams. The results of the analysis showed that the tree stands were divided into 3 strata, namely strata A with 17 individuals and strata B with 62 individuals dominated by Schima walichii, while in strata C there were 35 individuals with the dominant species being Maesopsis eminii. The resulting gap distance is 3-19 meters. There are 7 types of invasive alien plant species from a total of 89 species found in 47 families with 6 species that have an effect on threatening community stability with the largest invasion percentage being 46% of Clidemia hirta.
