Abstract. Poedjirahajoe E, Sulityorini IS, Komara LL. 2019. Short Communication: Species diversity of mangrove in Kutai National Park, East Kalimantan, Indonesia. Biodiversitas 20: 3641-3646. Kutai National Park (KNP) in East Kalimantan, Indonesia is blessed with natural mangrove forests. However, there is only very little information relating to the species composition and mangrove diversity. Therefore, this study was conducted to assess the mangrove tree species diversity and richness in Kutai National Park, East Kalimantan, Indonesia. The study results showed that the mangrove trees density was 1,214 trees/ha in the line transect vegetation survey with 1.7 ha plot. The number of mangrove species in KNP was 17 from 6 families. The dominant species with large numbers of individuals were Rhizophora mucronata, Rhizophora apiculata, and Bruguiera sexangula. The diversity index was low in mangroves in Pandan Bay Estuary, and Kaba Bay compared to that in Lombok bay’s mangroves.

A study on diversity and abundance of grasshopper and its relatives (Orthoptera) was conducted at two mountainous rainforest ecosystems (Mounts Kendeng and Botol) of Gunung Halimun-Salak National Park. A hundred meters of a line transect was used to sample and set up several insect traps (yellow pan, malaise, pit fall, bait pit fall, sweep net, and light traps), and insect sweepings as well. The light traps were set up at about fifty meters distance from the end of the sampling sites. A total individual collected by traps was combined on every comparable sampling site. Total individuals of the Orthoptera captured were 414; consisted of 25 species of 9 families. Both species diversity and number of families were higher at Mount Kendeng rather than Mount Botol. Number of species of each family usually similar except on family of Grillidae was much higher at Mount Kendeng. Species belong to Phasmidae was not recorded at Mount Kendeng, while species belong to both families of Gryllotalpidae and Tettigonidae were not captured at Mount Botol as well. Overal there was a difference in the species richness at each between. Shannon Diversity Index (H’) and evenness (E) were higher at Mount Kendeng (2.44 and 0.81) rather than Mount Botol (1.80 and 0.66). Similarity Index of Jaccard (Cj) and Sorenson (Cn) of both localities were similar (0.40 and 0.32). Herbivores were most dominant at both localities (Phasmidae, Tetrigidae, Acrididae, Gryllidae, dan Gryllotalpidae), followed by omnivores (Blattidae), scavenger (Gryllacrididae), and predator (Mantidae).

Abstract. Pototan BL, Capin NC, Delima AG, Novero AU. 2021. Assessment of mangrove species diversity in Banaybanay, Davao Oriental, Philippines. Biodiversitas 22: 144-153. This study determined mangrove species diversity and community structure in Banaybanay, Davao Oriental, Philippines. Ten 150m long transects plots were laid out perpendicular through the mangrove forests yielding 30 plots and total sampled area of 3, 000 m2. Individual trees within plots were counted, identified and measured for diameter at breast height (dbh) and tree height. For diversity analysis, Shannon-Weiner Index of Diversity (H’), Pielou’s Index of Evenness (J), Simpson’s Index of Dominance (C), and Effective Number of Species (ENS) were used. Results showed a total of 33 species belonging to 14 families, 31 of which are true mangroves and two associates. Two threatened species, the endangered Camptostemon philippinensis and vulnerable Avicennia rumphiana, and three near-threatened species were recorded. Diversity analysis showed a high diversity index (H’=3.145; ENS=23) and high species evenness (J=0.85) but low dominance (C=0.05). Sonneratia alba attained the greatest importance value (IV=59.79%) due to high relative density, relative frequency, and relative dominance. Also, Rhizophoraceae is the most represented among 14 families. Hence, Banaybanay being highly diverse with the presence of threatened and near-threatened mangrove species calls for immediate protection and conservation measures because of increasing anthropogenic activities and environmental problems observed in the area.

Djamaluddin R. 2018. The mangrove flora and their physical habitat characteristics in Bunaken National Park, NorthSulawesi, Indonesia. Biodiversitas 19: 1303-1312. The mangrove forests of Bunaken National Park are among the most distinctive andunusual in Southeast Asia because of the species that the forests contain. This study investigated the identity and diversity of mangroveplants as well as physiographic factors and major physical processes of every type of sub-habitats. Seven surveys were conducted tocollect and identify mangrove species of the park. Sub-habitats where specimen was found, aspects related to tidal inundation, nature ofsoil, freshwater influence and topography were observed as well as major physical processes influencing the condition of each subhabitat.The results suggested that the park was floristically rich with at least 27 plant species and they were distributed over tenrecognized sub-habitat types in different composition and diversity. Ceriops zippeliana Blume, Lumnitzera racemosa Willd, Lumnitzeralittorea (Jack) Voigt., Sonneratia ovata Backer, and Camptostemon philippinense (Vidal) Becc. were found in Bunaken National Parkand their presence confirmed the broader distribution limit of these species within Indo-Malesia region. A special notice was for C.philippinense as the distribution limit of this is rarely reported.

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.

This study aims to identify the species of mangrove constituents and determine the zonation of the growing community of mangrove plants from the seaward to the landward zone, of the Nature Conservation Forum (NCF) Putri Menjangan coastal Pejarakan village Buleleng from July to October 2017. Identification of mangrove plant species based on the following characteristics: habitus, root type, fruit shape, inflorescence, leaf shape and leaf arangement. Zoning of mangrove grown is determined from vegetation analysis conducted in 3 zones (front zone, middle zone and back zone) with quadrat method, the area of each square is 20 m x 20 m. Parameters specified in each kwadrat are the density, dominance and frequency of presence of each species. Zoning of mangrove community is determined based on the important value of mangrove plant species. The diversity of the mangrove community is calculated by the Shanon-Wiener Diversity Index. The results of the study identified 13 species of true mangrove plants (mangrove) and 14 mangrove mangrove associates. The dominant species are Sonneratia alba (important value / iv is 98.19), Lumnitzera racemosa (iv. is 40.75), Rhizophora apiculata (iv.is 35.53), Rhizophora mucronata (iv. 33.02), Ceriops decandra (iv.23.61) and Avicennia marina (iv. 22.22). The diversity index of mangrove species (H) is 2.07, then it is considered good. The pattern of growing mangrove plants in coastal Pejarakan Buleleng, in general follow the natural pattern of mangrove zonation. Typical characteristics and patterns of growing mangrove zonation become interesting attractions and reference for mangrove area managers in ecotourism development and efforts to conserve mangrove forests.

Abstract. Izzati U, Hasibuan HS. 2019. Riparian tree and bird diversity in Cisadane River, South Tangerang City, Indonesia. Biodiversitas 20: 595-603. Riparian is a riverbank area that has unique characteristics. It is a combination of terrestrial with aquatic habitats so that riparian ecosystems have high biodiversity values. Riparian is included in a protected area that is naturally designated for vegetation, but in reality, riparian areas, especially in urban areas, have a lot of conversion of land functions by humans so that it can disrupt diversity of tree and bird species. This study aims to identify the diversity of tree and bird species and the correlation between the two. Riparian length of Cisadane River, South Tangerang City is 20.15 km. The method used was plot line with size of 20 m x 20 m for tree data and line transect for bird data by systematic sampling with a random start then analyzed using Shannon Wiener index. The results obtained were found 22 tree species included in 11 families with species diversity index (H') of 2.707 and 40 bird species belonging to 25 families with species diversity index (H') of 2.794. The diversity of tree and bird species is classified as medium. The results of the analysis using the Pearson correlation between the diversity of tree with bird species obtained that there was no relationship between the two. Based on these results, riparian zones in urban areas need to be maintained and improved in quality so that the diversity of tree and bird species increases so as to create a stable ecosystem.

Diversity and characteristics of mangrove vegetation in Pulau Rimau Protection Forest, Banyuasin District, South Sumatra, Indonesia. Biodiversitas 20: 1215-1221. The purpose of the study was to analyze the flora diversity and characteristics of mangrove vegetation in Pulau Rimau Protection Forest, Banyuasin District, South Sumatra. Data collected were the number and girth diameter of mangrove tree species, and aquatic ecology parameters using transect method. The sample plots size were 2m×2 m; 5m×5 m; 10m×10 m; for seedling, sapling, and tree, respectively. The observation plots were arranged in a row of 120 m length on two sides of the forest edge, namely Calik Riverbank and Banyuasin Riverbank. Data were analyzed using importance value index (IVI), Simpson’s diversity index and Sørensen’s community similarity. The study revealed that there were differences in mangrove characteristics in two study sites. There were 57 plant species identified inside and outside sample plots, but only 15 species (26.32%) among them were categorized as true mangrove species. Inside the sample plots, there were 11 and 10 mangrove tree species recorded on the Calik Riverbank and Banyuasin Riverbank, respectively, but only 7 species among them were found in both sites. The mangroves on Calik Riverbank were dominated by Nypa (IVI 53.59%) and Bruguiera (51.12%), while those on Banyuasin Riverbank were dominated by Sonneratia (66.91%) and Avicennia (51.73%). The Simpson’s diversity index for Calik Riverbank and Banyuasin Riverbank was 0.82 and 0.78, respectively, whereas the Sørensen’s coefficient of community between the two sites was 0.67.

Merapi volcano as one of national park is an ecotourism site which is very potential to visit. Information about species diversity for a national park is very important especially if its area fluctuated susceptibly. Two years after 2010 Merapi eruption, there are no research about species diversity and evenness of Anuran in that place. The research is carried out during June-November 2012 which is dry season. The objective of this research is to study the species diversity and evenness of Anuran in southern slope of Mount Merapi. The research is carried out in 6 locations; those are Kali Kuning, Telogo Muncar, Telogo Nirmolo, Petak Pitu, Bukit Turgo, and Bukit Plawangan. We used Visual Encounter Survey (VES) method combined with transect in Kali Kuning, Telogo Muncar, and Petak Pitu. VES method combined with time search in Telogo Nirmolo and Bukit Turgo. VES method combined with track exploration in Bukit Plawangan. Species diversity is analyzed with Shanon-Wiener diversity index. Species evenness is analyzed with Pielou evenness index. Total individuals each species is counted to know species abundance. Species diversity of anuran in southern slope of Mount Merapi is consisted of 12 species’ which is distributed in 6 locations. The highest diversity and evenness of anuran is at Bukit Turgo (H’=1.31; E=0.94). The lowest diversity and evenness of anuran is at Petak Pitu (H’=0.49; E=0.3). Species diversity of anuran in southern slope of Mount Merapi is low (Bukit Turgo and Kali Kuning) and very low (Bukit Plawangan, Telogo Muncar, Telogo Nirmolo, and Petak Pitu). Species evenness of anuran in southern slope of Mount Merapi is stable (Telogo Nirmolo and Bukit Turgo), still labil (Bukit Plawangan, Kali Kuning, and Telogo Muncar), and oppressed (Petak Pitu).
