The study assessed the relative abundance and vegetation structure of African buffalo (Syncerus caffer) including plant parameters: frequency, diameter at breast height (dbh), tree height, diversity, evenness, richness, Margalef, dominance in Kainji Lake National Park. Point – Centered Quarter method was used for woody species enumeration. A total of twenty-eight (28) randomly sampled plots of 150m by 100m given 112 points per plot were established in the study area. The abundance and distribution, tree frequencies, heights, dbh and plant biodiversity indices were calculated using the Paleontological Statistics Software (PAST) for scientific data analysis. The results revealed that relative abundance of African buffalo in both morning and evening of dry and wet seasons in various habitats of the Park were 13.33 ± 4.41 and 11.33 ± 4.40 respectively. The study showed the highest mean value of 21.75 ± 6.94 representing 87 individuals in dry season compared to wet season with mean value of 15.25 ± 5.11 representing 61 individuals. A total of 91 woody plant species and 29 tree families were recorded in African buffalo habitats representing 80, 77, 68 and 59 tree species respectively. The highest average girth size of tree species was class between >10cm -50cm with 59.14 ± 4.06 and the highest mean tree height was height class of >3 - 10m with 91.43 ± 5.44. There were significant differences at (p<0.05) between the values of dbh, tree height, diversity, richness and evenness of plant species recorded in different habitats studied in the Park.

In the tropical rainforests of Jambi, Sumatera, a particular group of epiphytes, species in the genus Hoya, have significant potential to be developed as commercially valuable ornamental plants, because of the uniqueness and beauty of their flowers. Hoya spp. are epiphytic vines whose survival depends largely on the presence of carrier trees, i.e. phorophyte trees. The study reported here was conducted to identify the level of epiphytic association between phorophyte trees and identified Hoya species. The study found four Hoya species, namely: Hoya rintzii, Hoya revoluta, Hoya coronaria, and Hoya cf. caudata. The four species of Hoya were found growing on eleven different species of phorophyte trees. Based on the results of t-contingency tables it was found that there is no association between particular Hoya species and the particular phorophyte tree species. This conclusion was supported by the calculation of Jaccard association indices demonstrating that the association between Hoya spp. and phorophyte tree species is relatively weak. Crown cover and the diameter of the tree are two habitat variables that affect the presence of Hoya revoluta at the sites. The presence of Hoya caudata was influenced by the variable temperature, while the presence of Hoya coronaria was associated with humidity, but the degree of association was relatively weak. The most significant variables affecting the presence of Hoya rintzii were tree height and elevation.Key word: association, ephyphites, Hoya spp, phorophyte.

Because of that condition, stand structure especially the species composition and vegetation structure need to be researched. The aim of this research was to identify plant species and analyze forest vegetation structure. This research was conducted between March–April 2018 in the 15.500 ha area with 0.02% sampling intensity. Data was collected using grid line method that consisted of 34 sample plots with the 10 m distance between the plots and 20 m between the lines. The numbers of identified plant species at the research location were 43 species, classified by 10 families and 24 genera. Cinnamomum sintoc has a high level of dominance species. The forest vegetation was consisting by the different growth phases. The tree phase has the highest density of 3672 species/ha, while the seedling phase was lowest density of 1060 species/ha. The forest crown stratification were consisting of A, B, C, D and E stratum. The highest number of plants were from C strata for 4651 trees and the least from A strata with 25 trees with the highest tree was 42 m. Could be concluded that the composition of Mount Ciremai National Park forest have so many number of species and complex structure vegetation forest.

Abstract. Susilowati A, Elfiati D, Rachmat HH, Yulita KS, Hadi AN, Kusuma YS, Batu SAL. 2020. Vegetation structure and floristic composition of tree species in the habitat of Scaphium macropodum in Gunung Leuser National Park, Sumatra, Indonesia. Biodiversitas 21: 3025-3033. Scaphium macropodum (Miq.) Beumee Ex K Heyne is a member of Malvaceae tree species and globally recognized as malva nut and locally known as ‘kembang semangkok’, ‘tempayang’, ‘merpayang’ or ‘kepayang’. The nut of S. macropodum has many benefits for medicinal purposes, yet destructive extraction of this tree species has led them to extinction. Among its natural distribution in Indonesia, North Sumatra Province, Indonesia is known as its original range, but there is limited information about the existence of this species. This study aimed to determine the vegetation structure of some tree species in the habitat of S. macropodum in Sikundur, Gunung Leuser National Park, Sumatra, Indonesia. Purposive sampling technique was employed by creating line transect at some forest areas where the population of S. macropodum is known to grow naturally. Four line transects with each transect consisting of five plots with nested plots within were established to record data at four growth stages, resulting in 80 plots in total. The results showed that the Important Value Index (IVI) of S. macropodum within the floristic community at the studied area was 21.98, 13.85, 27.30, and 39.60 for tree, pole, sapling, and seedlings stages, respectively. The Shannon-Wiener Diversity Index (H) were 3.80, 3.70, 3.06 and 2.45, Index of evenness (E) are 0.94, 0.92, 0.86, 0.77 and the Index of Richness (R) are 11.76, 10.73, 6.59, 4.10 for tree, pole, sapling, and seedlings stages. This result suggests that the natural population of S. macropodum in Sikundur forest was still in good condition at all stages from tree to seedling.

Orangutan (Pongo pygmaeus morio) merupakan satwa langka yang harus dikonservasi melalui pelestarian Taman Nasional Kutai (TNK). Studi karakteristik sarang orangutan merupakan bagian dari upaya pelestarian. Metode yang digunakan dalam penelitian ini adalah menggunakan jalur transek dengan menghitung sarang orangutan serta mencatat karakteristik sarang orangutan yang meliputi kelas sarang, posisi sarang, tinggi sarang, tinggi pohon, diameter pohon dan jenis pohon sarang. Pada lokasi penelitian ditemukan sebanyak 173 sarang orangutan yang terdiri dari 84 sarang di resort Sangatta dan 89 sarang di resort Sangkima. Jenis sarang didominasi oleh kelas sarang C dan D dengan posisi sarang sebagian besar terdapat pada ujung dahan (UD) di resort Sangatta, posisi sarang terbanyak ada pada ujung dahan (UD) dan pucuk pohon (PP) di resort Sangkima. Rata-rata tinggi sarang orangutan adalah 12,2 - 40,2 m, diameter pohon 17,4 - 110 cm, dan tinggi pohon 12,2 - 40,2 m di resort Sangatta. Pada resort Sangkima rata-rata tinggi sarang orangutan adalah 10,2 - 24,2 m dengan diameter pohon 20 - 109,4 cm dan rata-rata tinggi pohon 14-28,6 m. Karakteristik sarang orangutan menjadi indikator kondisi habitat orangutan yang ada di TNK. Orangutan (Pongo pygmaeus morio) is a rare animal that must be conserved through the preservation of the Kutai National Park (KNP). Study of orangutan nest characteristics is part of conservation efforts. The method used in this study is to use a transect line by counting orangutan nests and noting orangutan nest characteristics which include nest class, nest position, nest height, tree height, tree diameter and nest tree species. At the study site, 173 orangutan nests were found, consisting of 84 nests at Sangatta resort and 89 nests at Sangkima resort. The nest type is dominated by the nest classes C and D with the nest position mostly found at the tip of the branch (UD) at Sangatta resort, the position of most nests is at the tip of the branch (UD) and tree tops (PP) at the Sangkima resort. The average height of orangutan nests is 12.2 - 40.2 m, tree diameter 17.4 - 110 cm, and tree height 12.2 - 40.2 m at Sangatta resort. At Sangkima resort, the average height of orangutan nests is 10.2 - 24.2 m with a tree diameter of 20 - 109.4 cm and an average tree height of 14-28.6 m. The characteristics of orangutan nests are an indicator of the condition of orangutan habitat in KNP.
