Species Strategy in Early Stage of Secondary Succession Associated with Soil Properties Status in a Lowland Mixed Dipterocarp Forest and Kerangas Forest in East Kalimantan.

Abstract

Studies on the early secondary succession were carried out in a lowland mixed Dipterocarp forest and a kerangas (heath) forest in East Kalimantan, Indonesia. The results show that there is a correlation between the species strategy with the physical and chemical soil status in the early secondary succession. In Mixed Dipterocarp Forest (Red- Yellow Podzolic soils) seedlings of secondary species were important as the initial colonizers. In contrast, vegetative resprouts (trees and shrubs) were the main component of Kerangas Forest (Podzol soils). A model of species strategy in relation to changes in soil property associated with the early secondary succession is presented.
