Abstract

Kayu afrika (Maesopsis eminii) is classified as one of the invasive species that exists in Indonesia. The presence of kayu afrika in Gunung Halimun Salak National Park pose a threat to a native species in that area. The aim of this research is to analyze the structure and composition of the forest stand and predict the distribution pattern of kayu afrika as an invasive species. This research use stratified random sampling method by make a 3 strip plots with 100 m x 20 m size in each zone including utilization zone, jungle zone, and core zone. The result shows that the utilization zone is dominated by pinus (Pinus merkusii), meanwhile the jungle zone is dominated by kayu afrika (Maesopsis eminii), and the core zone is dominated by puspa (Schima wallichii). All the three zones have a normal stand structure. The distribution of kayu afrika (M. eminii) has reached the core zone. The density percentage of kayu afrika (M. eminii) compared to other species is 27,19% in the utilization zone, 28,14% in the jungle zone, and 16,59% in the core zone.

Keywords: Distribution pattern, utilization zone, jungle zone, core zone
