Komposisi Jenis Dan Struktur Vegetasi Hutan Dataran Rendah Di Kompleks Gunung Bulusaraung Sulawesi Selatan

Abstract

The Bulusaraung Mountain is a lowland forest and is one of the main ecosystems owned by Bantimurung Bulusaraung National Park. Therefore, this study aims to determine the species composition and vegetation structure of lowland forests in the complex of Bulusaraung Mountain. The research was conducted from April to May 2018. Data collection was carried out using a 20 × 20 meter plot placed on the Balleanging, Tokaddaro and Tompobulu track lines based on altitude (550 m asl, 650 m asl, and 750 m asl). The result of this study show that there are 44 species were found on tree class, 65 species on pole class, 40 species on sapling class and 25 species on seedling class. The species composition in the study area was dominated Palaquium obovatum, Persea rimosa, Arthrophyllum diversifolium, Cryptocarya laevigata, and Engelhardia serrata, while Psychotria leptothyrsa, Antidesma bunius, Maesa ramentacea, Ficus sandpaper, Baccaurea javanica, Symplocos maliliency, Callicarpa pentandra, and Saurauia tristyla is a type of tree that differentiates at each altitude. The structure of the forest canopy layer at an altitude of 550 m above sea level consists of three canopy layers, while at an altitude of 650 and 750 m above sea level consisting only of two canopy layers. The cover of forest canopy in all sampling locations was reached 75-90%.

Composition and diversity of tropical forest vegetation at Sibolangit tourism park, North Sumatra, Indonesia

“…This species was also dominant at the tree stage (22% of IVI). At the tree and pole stage, stem diameter affects the value of the important index along with the density and frequency of a species [18].…”

“…A diversifolium, M maingayi, and S ceylanica were also dominant in the study location. A previous study stated that A diversifolium was also one of the dominant species at Mount Bulusaraung [18]. The Importance Value Index of a species illustrates that the existence of that species is more stable or has the opportunity to be able to maintain the growth and sustainability of the species [19].…”

“…The high IVI of a species at the sapling and seedling stage is caused by the density and frequency that are highly and evenly distributed throughout the area [18]. 34 species were recorded at sapling stage with Mitrephora obtusa as the dominance species (35% of IVI) (Table 3).…”

Vegetation Characteristics of The Maleo Bird (Macrochepalon Maleo) Habitat at Natural Tourism Park of Towuti Lake, South Sulawesi

“…Hal ini juga menunjukkan vegetasi sebagai cover tidak hanya jenisnya yang dibutuhkan burung maleo melainkan juga dari struktur dan komposisinya. Vegetasi sebagai cover memberikan kesejahteraan kepada satwa dengan menyediakan fungsi berkembang biak, makan, bersarang atau istirahat (Bailey, 1984) (Asrianny et al, 2019). Sementara penelitian (Ismaini et al, 2015) menyatakan bahwa INP jenis tumbuhan disuatu komunitas merupakan parameter yang dapat menunjukkan peranan jenis tumbuhan dalam komunitas tersebut.…”

Does Altitude and Forest Density Affect Economic Growth? a Case Study of Kalimantan Barat

“…Based on the morphology of higher areas, it has more significant challenges to be explored and exploited. Meanwhile, the lower sites are mainly used for more comprehensive land needs, such as housing and agriculture (Asrianny, Paweka, Achmad, Oka, & Achmad, 2019). If managed optimally, areas with more comprehensive forest cover should increase economic growth in those areas.…”
