Species Composition, and Diversity of Mataram University Green Open Space, West Nusa Tenggara

Abstract

Abstract Mataram university green open space (GOS) is one of the partial green open spaces (GOS) approaches that can be used to conserve endemic germplasm as well to fulfil the proportion and distribution of urban forests. This research aims to describe the species composition, and diversity including the authenticity of Flora Malesiana in this area. We used a census method (100% measurement) to identify the species and measured the diameter and height of all tree species with the diameter of more than 2 cm. The results showed that the 99 species belonged to 85 Genera, 39 families with a composition of 61 species (61.62%) including the flora Malesiana and 38 species (38.38%) including exotic species. Based on IVI analysis showed that Ptychosperma macarthurii dominated at the sapling level while Swietenia mahagoni dominated at the pole and tree levels. The H’ of diversity is in the medium category with the sapling level has the highest value (3.42).
