MANSUR, M & KARTAWINATA, K. 2017. Phytosociology of a Lower Montane Forest on Mt. Batulanteh, Sumbawa, Indonesia. Reinwardtia 16 (2): 77-92. — While Indonesia’s forests are globally known for their high species diversity but many regions remain little known to investigate the tree community in a lower montane forest at Mt. Batulanteh in Sumbawa. We subjectively laid out plots of 1,800 m2 each, two in secondary forests and one in a disturbed primary forest. All stems over 5 cm diameters were measured and identified. In the plot of 0,54 hectare, we recorded 723 individuals, representing 78 species, 60 genera and 33 families. Estimated volume of boles was 183.2 m3/0.54 ha, biomass was 220.1 tons/0.54 ha, carbon stock was 110.0 tons/0.54 ha and CO2 sequestration was 403.1 ton/0.54 ha. The forest at Mt. Batulanteh is classified as Garcinia-Cryptocarya association consisting of Micromelum-Cinnamomum subassociation. Dipterocarpus-Calophyllum subassociation and Garcinia-Syzygium subassociation. Dominant species were Micromelum minutum (IV=27.24), Mallotus philippensis (IV=26.2), Cryptocarya ferrea (IV=24.71) and Cinnamomum burmanni (IV=23.81) in Plot 1, Dipterocarpus retusus (IV=77.4) and Calophyllum soulattri (IV=24.21) in Plot 2, and Garcinia celebica (IV=34.86) and Syzygium sp. 1 (IV=34.76) in Plot 3. Dipterocarpus retusus was unique of having restricted distribution. Fagaceae, typical family in montane forests, was absent. Shannon’s diversity index was low (H '= 1.61). It can be concluded that the plots do not constitute a representative of Mt. Batulanteh and the surrounding forests, but they were sufficient to provide an illustration of the forests locally. The diameter class distribution indicated that the forests were regenerating. They were developing secondary forest and regenerating disturbed primary forest; slow successions were in the process and could be enhancedby ecological restoration. Further botanical explorations in poorly known regions of Sumbawa should be intensified further.

Siregar M, Undaharta NKE. 2018. Tree standing dynamics after 30 years in a secondary forest of Bali, Indonesia. Biodiversitas 19: 22-30. Tree standing dynamics in 0.5 ha plot after 30 years in Bukit Tapak secondary forests, Batukahu Nature Reserve, Province 0f Bali was studied by using plot method. The results showed that the tree species richness is same, 33 species, but there are six species disappear and be replaced by another species as a newcomer. Eight species persist as major species based on the importance value, namely: Homalanthus giganteus, Vernonia arborea, Dendrocnide stimulans, Meliosma angustifolia, Saurauia reinwardtiana, Trema orientalis, Macaranga triloba and Polyosma integrifolia. Tree density decreased 19.7%, but the total basal area increased 12.2% with an average basal area per tree were also increased by 39.7%. Shannon diversity index (H`) and Equitability index (E) was increased in 2016. Forests in the plot categorized as old secondary forest are still in the process of maturation toward the primary forest. Species predicted would disappear with a succession of increasingly advanced process is Trema orientalis, while the predicted to survive for much longer are Homalanthus giganteus, Acronichia trifoliolata, Meliosma angustifolia, Polyosma integrifolia, Saurauia reinwardtiana and Dendrocnide stimulans.

Shade Tolerant Species

Seed mass values are given for 140 species of primary lowland rain forest and associated secondary forests in Singapore. Among shade-tolerant species of primary forest there is a trend for a decrease in mean seed mass with tall trees > woody climbers > small trees > shrubs > herbs; the differences between tall trees and small trees or shrubs or herbs, and between herbs and small trees or woody climbers are significant. There are a few light-demanding herbs or shrubs in the primary forest; among small trees, light demanders have significantly lower seed mass values than shade tolerators. In 9 out of 13 comparisons within taxa including both shade tolerants and light demanders the former had appreciably larger seeds than the latter. Two out of 13 comparisons involved very small seeded shade tolerators, and one a notably large-seed light demander. Many shade-tolerant herbs, shrubs, and trees have seed mass values much smaller than those of trees of secondary forest conventionally regarded as small seeded, and exploit moist, litter-free sites, e.g., steep microslopes. The trees of secondary forests on degraded soils do not differ significantly in seed mass from those on nondegraded soils. Key words: seed mass, light requirement, regeneration, tropical rain forest, phylogenetic analysis.

Microhabitat use and habitat-abundance relationships of four freshwater shrimps, Atyopsis moluccensis, Macrobrachium pilimanus, Macrobrachium trompii and Macrobrachium neglectum, were surveyed in tropical streams running through primary and secondary forests in Borneo, East Malaysia. Underwater observations revealed that A. moluccensis preferred relatively high water velocity and a boulder substrate. Macrobrachium pilimanus also preferred high water velocity and a cobble substrate, whereas M. trompii occupied stream margins with slow current and fine substrates (from POM (particulate organic matter) to pebbles). In contrast, M. neglectum was distributed relatively evenly through the stream channel. The abundance of A. moluccensis, M. pilimanus and M. trompii in the stream reaches was best explained by the abundance of boulders, cobbles and POM, respectively, suggesting that the amount of preferred microhabitat is an important factor affecting shrimp abundances in the tropical rain-forest streams. The primary-forest reaches were dominated by coarse substrates, such as cobbles and boulders, while a great proportion of the streambeds in the secondary-forest reaches were covered with sand. Owing probably to such habitat differences, the abundance of both A. moluccensis and M. pilimanus, which preferred coarse substrates, was less in the secondary- than in the primary-forest reaches. These suggested that loss of preferred habitat, namely decreased coarse substrate availability, by sedimentation resulting from riparian deforestation had altered the shrimp assemblage structures.

ABSTRACTTrapping was conducted in primary and secondary forests to investigate the effects of past logging on small mammal communities. Thirteen I-ha sites were snap-trapped for three consecutive days in tropical monsoon rainforest in Xishuangbanna Nature Reserve, southern China. A total of 3900 trap-days yielded 198 captures, of which 118 were in the primary forest and 80 in the secondary forest. A total of 12 ground-dwelling species (eight Rodentia, Muridae; three Insectivora, Soricidae; one Insectivora, Erinaceidae) were caught, five (all Rodentia, Muridae) occurred in the primary forest and 11 in the secondary forest. The most abundant species was Niviventer confucianus, accounting for 62% and 39% of the total captures in the primary and the secondary forests, respectively. In the secondary forest the mean abundances of the two dominant species, N. confucianus and Maxomys surifer, were reduced, and a non-commensal form of Rattus rattus disappeared, but N. fulvescens showed no change while Mus pahari increased. The seven species which occurred only in secondary forest had very low abundance. Overall, the multivariate Mantel test showed the two communities to be significantly different. After logging, species diversity increased, and the two dominant species had increased body mass and their mean abundance decreased.

Relative Contribution

Succession following deforestation in Neotropical forests has been investigated extensively, yet rarely have studies connected nutrient dynamics with vegetation. This study was conducted in lowland wet forests of Maquenque, Costa Rica. The objectives were (1) to compare carbon (C), nitrogen (N), and phosphorus (P) characteristics and understory vegetation diversity between regenerating forests and primary forests; and (2) to use these variables to evaluate P. macroloba’s successional role. Four 300 m2 plots were established in primary and secondary forests where P. macroloba was the dominant N-fixing tree. Soil and vegetation data were collected from 2008 to 2010. Values of indicators of C, N, and P cycle activity were generally greater in primary than in secondary forest soils. Efficiency of organic C use and the relative contribution of respiration and organic C to soil biomass were also greater in the primary forest. These trends corresponded with greater richness, biomass, and cover of total and leguminous plant species, greater volume of P. macroloba in primary stands, and greater density of P. macroloba in secondary stands. As cleared regions of former primary forest regenerate, P. macroloba is the important dominant N-fixing tree and a critical driver of C, N, and P recuperation and ecosystem recovery.

Abstract. Karmini, Karyati, Widiati KY. 2021. The ecological and economic values of a 50 years old secondary forest in East Kalimantan, Indonesia. Biodiversitas 22: 4597-4607. Secondary forests in the tropics are often ignored since they are assumed to have low ecological functions while on the other hand the economic values have been reduced. This study aimed to analyze the ecological and economic values of a 50-year secondary forest in East Kalimantan that experienced several various land-use changes. The ecological aspects analyzed were stand structure, floristic composition, and species diversity. Economic aspects include log prices, logging costs, profit margins, and stumpage values. A vegetation survey of woody trees with a diameter at breast height of more than 5 cm was carried out on ten plots measuring 20 m × 20 m each. A total of 437 trees belonging to 38 species, 30 genera, and 19 families were recorded with Moraceae and Euphorbiaceae were the most dominant families with Family Important Value (FIV) of 86.79. The three most dominant species were Macaranga motleyana (IVi of 50.95), Artocarpus elasticus (IVi of 34.41), and Symplocos fasciculata (IVi of 31.46). The trees in the study plot have a diversity index of 1.33, dominance index of 0.07, evenness index of 0.37, and species richness of 6.09. The average logging cost, logs price, lumber price, profit margin, and stumpage value at secondary forest were USD69.43 m-3, USD44.63 m-3, USD100.03 m-3, USD10.30 m-3, and USD28.73 ha-1, respectively. The 50 years old secondary forests in East Kalimantan have biodiversity, especially trees that have economic value, therefore their existence needs to be preserved and their use is carried out by maintaining and increasing biodiversity.

Lore Lindu National Park in Central Sulawesi is one of the protected areas. Although it is protected, many of its areas are experiencing pressure and disruption by human activities. The purpose of this research was to know the relationship between farmers’ income and land cover change at Lore Lindu National Park. The research method was a participatory survey. Variables of incomes were sourced from farming and outside farming (forests). Data of land cover change were obtained using imagery in 2012, 2014 and 2016. The result of research is the average of farming income of IDR 1,387,077 (cocoa farming) and non-farm income of IDR 854,819 (forest honey, resin). In the last five years (2012-2016), the primary forest area decreased by 902.37 ha, while the secondary forest has shown an increase of 2,233.61 ha. The trend of land cover change was drastic, with change in the secondary dry land forest area from 6.9 ha (in 2012) to 2,240.5 ha (in 2016). The increased secondary forest area and the secondary forests have been converted into agricultural land and mixed gardens.

Abstract This study aimed to determine changes in litter biomass and the effect of changes in litter biomass on carbon stock changes in Permanent Sample Plots of primary and secondary forest in the Protection Forest of Soya Village, Ambon City, for three years of measurement. This study used a sampling method with harvesting/collection and using laboratory analysis, where the working procedure used the SNI: 7724 guidelines. The data taken includes the water content of litter, total wet weight, dry weight of the sample, and wet weight of the sample to calculate the range of biomass or organic matter and carbon content of litter organic matter. The results showed that the average value of water content in both primary and secondary forests decreased. The depletion degree was higher in the first year than the second and third year. The biomass content of litter in primary forests decreased from year to year for three years of measurement. It causes a decrease in the carbon content in the primary forest. In contrast, the biomass content in secondary forests increased from year to year and increased carbon content from year to year for three years of measurement.

This study aims to determine the diversity of butterflies at the Gunung Raya Wildlife Reserve, South Sumatra. The research was conducted in January-February 2018. The research sites were 4 different habitat types, namely primary forest, secondary forest, riparian area, and bush and plantation. Data collection uses direct observation and capture techniques along the transect line (linear transect counting) along 1000 m in each habitat type using insect nets. The results of the study obtained 55 butterfly species belonging to 5 families (there were 13 species of Papilionidae, 30 species of Nymphalidae, 7 species of Pieridae, 1 species of Riodinidae, and 4 species of Lycaenidae). The highest Shanon diversity index is in primary forest habitat (Manduriang) with H'= 3.5; followed by shrubs and plantations (Pasir Bintang) with H'= 3.45, and riparian areas (Talang Lebong) with H' = 3.23; while the lowest is secondary forest (Mesagih) with H'= 2.94. Distribution of species in all locations  is relative (E> 0.9) and high species richness (R> 4). 2 butterfly species protected by Regulations of the Environtment and Forestry Ministers No 20 of 2018, namely Troides helena and Trogonoptera brookiana has been found in this study.
