Diversity, dominancy and density of Tree Stage Plants of Sriwijaya University Forest Area Indralaya

Abstract

There have been various environmental changes that have occurred within the Unsri campus area. After more than 30 years due to various factors such as the existence of human intervention activities has made swamp area narrow and will have an impact on changing diversity especially swamp edge tree vegetation in the Unsri campus area, it is necessary to conducted research that aimed to know diversity, dominancy and density of tree stage plants at Sriwijaya University campus area forest, Eight plots (10x10 m2) had been made and allthe trees with more than 10 cm diameter were counted. Simpson formula of dominancy and diversity were used and found index of dominancy 0.65 and diversity index is 0.35. Furthermore, density of trees is 31/800 m squares. Low index of diversity is caused by poor of species (two species Acacia mangium dan Melaleuca cajuputi).
