Characteristics of growing sites Anisoptera thurifera in South Manokwari West Papua

Abstract

Anisoptera thurifera is a type of Dipterocarpacea family that dominates lowland tropical forest areas. In line with the growth and development of human needs for timber forest products, the existence of this species is also diminishing in nature. For this reason, information about the characteristics of the type of growing place is very much needed, as initial information for the potential development of this type as a silviculture tree species in the future. The location where A. thurifera grow naturally is observed at the Manokwari Selatan protected forest. Observed data included ecological and demographic aspects of the plant by using Systematic Continuous Strip Sampling (SCSS) for the observation of A. thurifera. While the 17.8 m circle is used for observing the ecological habitat of A. thurifera. The results showed that A. thurifera was found in the study area was in the edaphic conditions in which A. thurifera grew were in slightly acidic to acidic soil conditions, even though the CEC was 45.32. The potential of this type is very worrying, it can be seen from the decline in the IVI value of the tree level to the seedling level. Although this plant is able to associate with several other types in its development, it is necessary to focus on more neutral edafic characteristics.
