Penetration of Sunlight in the Multilevel Crown: A Case Study in Tropical Rain Forest

Published: 04 January 2016 Publication History

Abstract

Light has been recognized as being one of the major factors influencing the tree growth. This study highlighted on the formulation of mathematical equations for the percentage of sunlight absorb by the trees. The tree status (such as dominant, intermediate or suppress) were determined based on crown expose to sunlight index. Tree variables data were collected from twenty long term permanent sample plots in five clusters. The trees were aggregated into five species groups based on the commercialized of the species. T-test confirmed that two of the species groups were significantly different in annual diameter increment between dominant and suppress. Analysis of variance test showed the absorption of sunlight was not equal among the species groups. The results will contribute to the improvement of the decision making process of the sustainable management of tropical forest and also improve its information database system.
