A Study of the potential collections of Javanese native tree species in the Bogor Botanical Garden for aesthetic functions in the landscape

Abstract

The selection of tree species planted for aesthetic functions may vary based on their physical appearance and it is very important to use the species of the native trees for ecological purposes. The objectives of this research were to assess the ecological distribution and the aesthetical performance of the collections of the Javanese native trees at the Bogor Botanical Garden. The data were processed and analysed based on habitat distribution and morphological characteristics. Furthermore, the Key Performance Index Assessment Technique was used to give value to each criterion. The stages of tree aesthetic quality assessment were done by simulation using the method of Scenic Beauty Estimation (SBE). Total 469 species of the Javanese native trees were discovered. Based on the habitat distribution, the highest number describes the species of tree scattered throughout the Island of Java (237 species), Western Java (131 species), West and Central Java (53 species), Central Java (17 species), central and eastern Java (12 species), eastern Java (9 species), and western and eastern Java (7 species). Furthermore, the species of native trees also had a range of habitat altitude ranging from coastal (0 masl) to mountain (3100 masl). Then, based on the criteria of aesthetic assessment, they were categorized as good (43 species), medium (172 species) and bad (14 species).
