“…Based on their habitus, the undergrowth is classified as herbs (15 species), shrubs (14 species), lianas (3 types), ferns (6 species), and palms (1 species). Similar research has been conducted in the other pine forest area (Destaranti et al 2017;Djufri 2003;Kunarso and Azwar 2013;Purnomo et al 2018;Yusra et al 2017). In the pine forest owned by PT.…”

“…Several studies have been reported that undergrowth vegetation has the potency to be used as food, medicine, forage, and botanical insecticides (Abdiyani 2008;Hadi et al 2016). Djufri (2003) suggested that the presence of undergrowth vegetation could be used as an environmental indicator. In addition, undergrowth vegetation has an essential role in the forest ecosystem and microclimate (Hilwan et al 2013).…”

“…Several studies have been conducted on undergrowth vegetation inventories in various plantation forests, such as in pine (Destaranti et al 2017;Djufri 2003;Kunarso and Azwar 2013;Purnomo et al 2018;Yusra et al 2017), Swietenia macrophylla, Peronema canescens, Schima walichii (Kunarso and Azwar 2013), Casuarina equisetifolia (Atmanto et al 2017), Agathis alba (Purnomo et al 2018), Enterolobium cyclocarpum, and Samanea saman (Hilwan et al 2013). The results of the previous research showed that species, numbers, habitus, and distribution of undergrowth were diverse.…”

Data on the biodiversity is essential to support the Forest Area with the Special Purpose (KHDTK) of Gunung Bromo as an educational forest and training center. This study aimed to obtain basic information on undergrowth vegetation composition under pine stands. Furthermore, the important value index (IVI), species diversity index (H’), species richness index (R), and evenness index (E) were determined. The data was systematically obtained by marking 35 plots of 2 m × 2 m. The distance between plots was 100 m. The results showed that the undergrowth vegetation consisted of 39 species from 26 families. The habitus of undergrowth vegetation was herb (15 species), shrub (14 species), liana (3 species), fern (6 species), and palm (1 species). Eragrostis tenerum was the dominant species with an IVI of 58.84%). Centrosema pubescens showed an IVI of 18.38%, while the other species showed less than 10%. Furthermore, H’ was classified as moderate (2.35), R was classified as moderate (4.69), and E was classified as uneven (0.64). This condition indicated that the undergrowth species that grew in KHDTK of Gunung Bromo was limited and uneven. It was considered due to inhibiting factors such as allelopathy in pine leaf litter and low light intensity. Undergrowth species that grow in KHDTK of Gunung Bromo showed several potential utilizations, such as medicinal plants (30 species), ornamental plants (9 species), food sources (5 species), forage (4 species), culture and crafts (4 species), and conservation (3 species).

“…The similarity of species was shown at the various growth stages of seedlings, saplings, and poles with SI values > 50%, while in the case of adult trees SI value was reported 46.75% which showed higher dissimilarity. Djufri (2003) suggests that if the SI value is greate0072 than 75% the similarity criterion is very high, while when it is in the range of 50 -75%, 25 -50%, and < 25% it comes under the categories of high similarity, low similarity, and very low similarity respectively. Many tree species are that are present in the large channel are not found in the small channel and vice versa.…”

Peat swamp forests are playing important role in climate change by carbon storage, biodiversity conservation, and crucial local livelihoods. The construction of drainage channels in Sebangau National Park, Indonesia negatively affects the Peatland ecosystem and degrades the vegetation diversity. This research aims to study the composition and vegetation diversity of secondary peat swamp forests in Sebangau National Park (SNP), especially around large and small drainage channels. For the observation of vegetation composition and diversity, each observation block consisted of 3 transects that were 300 m apart from each other, and perpendicular to the channel. For observations on small drainage channel blocks, transects are made to continue the previous transect at a distance of 500 m from the end of the large drainage channel. On each transect, 5 plots of vegetation were made using the plot line method with a distance of 50 m between each plot. A total of 15 plots of 30mx30m size were prepared for each drainage channel category. Observations were made on the growth rate of seedlings in a 2m x 2m plot, poles in a 5m x 5m plot, saplings in a 10m x 10m plot, and trees in a 20m x 20m plot. The results of the study showed that Shorea spp., Combretocarpus rotundatus, Cratoxylum arborencens, and Calophyllum sp. are the dominant plant species of the study area. Overall 92 species were reported from the Large Drainage Channel block and 86 species from the Small Drainage Channel block. Further, the Species Diversity ranged between 1.43 - 1.57 while Species Richness ranged from 16.80 – 23.03, and the Evenness Index ranged from 0.83 – 0.92 at all levels of vegetation growth. Results of the study can be concluded that the channel dimensions do not have any effect on species number, diversity index, species richness, and species evenness at all levels of vegetation growth. The Similarity Index of species at seedlings, saplings, and poles is more than 50%, while at the tree level it was reported less than 50%.

“…When there were unidentified species, the samples were made into herbarium specimens to be further identified in Herbarium Bogorense in Bogor. To compute the importance value (IV) of each species, formula according to Cox [10] was applied as follows: NP = Relative Frequency (RF) + Relative Density (RD) + Relative Dominance (RD). The value of Species Diversity Index (H') ranged from 0-7 of the Shannon-Wienner were interpreted using the following criteria: If H' ≤ 1, category was very low; if H' ≥ 1-2, the category low; if H' ≥ 2-3, the category was medium; if H' ≥ 3-4, the category was high; and if H' ≥ 4 the category was very high [11,12,13,14].…”

A study entitled “Vegetation Analysis of the Forest Park of Pocut Meurah Intan, Seulawah Subdistrict of Aceh Besar, Aceh Province” has been conducted since April 2019 until November 2019. A transect method and squares were used in this study. The transect method was used to record species composition throughout the observation stations (inventory of species), including stands of pine (Pinus merkusii) with ten stations transect, stands of eucalyptus (Eucalyptus urophylla), stands of cacao (Theobroma cacao), and natural forests within a radius of 2 km around the THRPMI office. The squares method was used to record the species in the same locations to replicate each station by ten squares of samples for vegetation analysis. The parameters measured in the field were frequency, density, and dominance of each species. Analysis of vegetation covered Importance Values (IV), Diversity Index (H ’), and the Similarity Index (SI). Results showed that there were 49 familia found with the composition of species in the entire observation stations comprising of 111 species with 58 species of trees, 12 species of shrubs, and 41 species of herbs. Additionally, the results showed that the species of vegetation with the highest IV were coarse grass (Imperata cylindrica), lawn pait (Axonopus compresus), and selasi (Vernonia cinerea) with IV of 72.01, 65.34, and 57.24, respectively. Results of analysis Species Diversity Index (H ’) showed that the Pinus merkusii had H’ of 2,134, whereas Eucalyptus urophylla had H ’of 1.965, and Theobroma cacao had H’ of 1,067. The results of the analysis of Community Similarity Index showed that all stations had the same relative SI of 75%. It can be concluded that the species composition of the study area dominated by tree species, species diversity index (H ’) in all observation stations varied ranging from 1.067 to 2.134, and the relative Community Similarity Index was 75%.
