Distribution Pattern and Population Structure of Cananga odorata (Lamk) Hook.f.et Th., in Natural Forest of Palanro and Natural Forest of Karaenta (a) Faculty of Forestry, Hasanuddin University, Indonesia Abstract This research aimed to determine the distribution patterns and population structure of Cananga odorata at Natural Forest of Palanro and Natural Forest of Karaenta of Maros Regency. The research was conducted in 6 transect samples located purposixely in the three forest types: secondary natural forest of Palanro, secondary natural forest of Karaenta and primary natural forest of Karaenta. The size of each transect was 20 m x 200 m which each of them divided into unit of 10 m x 10 m. So that, there are 40 units on each transect and the total number of unit was 720 units. Data was collected by measuring the diameter, and coordinate x and y of each individual in every unit, and counting the number of seedling in each unit. Population structure was obtained by counting the total number of cananga at each every growth level and distribution pattern was analyzed using the Morishita distribution index. The research results showed no Cananga odorata was found in secondary forest of Palanro, but Cananga odorata was found in secondary forest and primary forest of Karaenta. The population structure of the Cananga odorata formed almost J shape which indicates that cananga can grow and regenerate in the natural forest of Karaenta because it has abundant number of seedling, as well as sapling and pole levels. Distribution pattern was indicate that the distribution of Cananga odorata is clumped at each growth level.
