Density Effects and Stand Density Management Diagram for Merkus Pine in the Humid Tropics of Java, Indonesia

Abstract

planting density and the practice of thinning. Density effects on stand growth and Pinus merkusii Jungh. et D HtMortality and D growth were positively density related, but H growth was not affected by density. During the measurement period, tree density decreased from 7779 to 679Results suggested that optimal harvesting was at about 30 years of age if no thinning occurs. The SDMD was established to predict the course of stand development in merkus pine. The simulation of stand growth under 2m x 3 m spacing and thinning

Land Use Systems, Soil Texture, Control Carbon and Nitrogen Storages in the Forest Soil of UB Forest, Indonesia

“…This is due to the existence of big trees (DBH 30 cm) which are still pronounce in the protected area (29-38%). The protected area (PA) is dominated by shrubs and not being used for agriculture due to the area is very steep slope (> 40%), while in PC there is plant weeding conducted by farmer resulted a lower standing leaf litter mass as compared to PA. Beside, the pine density in UB Forest East Java (277 -322 trees/ha) was lower than pine density in production forest West Java -Indonesia that had 50% thinning (400 trees/ha) as studied by Heriansyah, Bustomi, & Kanazawa (2008).…”

A Decision-Support Model for Regulating Black Spruce Site Occupancy Through Density Management

“…in Bulgaria (Stankova & Shibuya, 2007), Merkus pine (Pinus merkusii Jungh. et de Vriese) plantations in Indonesia (Heriansyah et al, 2009), and Eucalyptus globulus and Eucalyptus nitens short rotation plantations in Southwestern Europe (Pérez-Cruzado et al, 2011). Analytically, the development of SDMDs has been characterized by a sequence of continuous incremental advancements in which increasingly complex and innovative model variants have been proposed.…”
