Soil macrofauna has an important role in the ecosystems and soil fertility. Agroforestry patterns have environmental benefits such as providing living space for biodiversity including soil macrofauna. This study aims to measure the influence of teak and kimpul agroforestry on the diversity of soil macrofauna. The study was conducted on teak and kimpul agroforestry demonstration plots in the KPH Yogyakarta in January 2019. The research method used was monolith and hand sorting techniques and the analysis was carried out descriptively using the species diversity index approach. The results showed that teak and kimpul agroforestry patterns did not affect on the diversity of species and density of soil macrofauna. The level of diversity of soil macrofauna in teak and kimpul agroforestry, teak monoculture and kimpul monoculture are low. The value of soil macrofauna diversity in teak and kimpul agroforests is higher than teak monoculture and kimpul monoculture. A total of five types of soil macrofauna were found in 12-year teak agroforestry, six types in 42-year teak agroforestry, five types in 12-year teak monoculture, eight types in 42-year teak monoculture and five types in kimpul monoculture. The dominant soil macrofauna are Microtermes sp. and Anomala sp.

Four sample plots, each of size 20m by 20m were systematically distributed in two strata (i.e. two plots in bat-occupied zone andthe remaining two plots in bat-unoccupied zone, to serve as control units). Using six (20m × 20m) sample plots each, basal area,canopy, and heights of trees with DBH 1m were measured. Fourteen individual trees were recorded in the bat-unoccupied zone,resulting in only seven tree species. On the other hand, 16 tree species, corresponding to a total of 25 trees were recorded in thebat occupied zone. Albizia zygia, Antiaris toxicaria, Azadiractha indicia, Holarrhena floribunda, Morinda lucinda, and Sterculiatragacantha were common to both zones. The Shannon Wiener species diversity index was found to be higher (H1=1.92) in batoccupied zones and lower (H1=1.45) in bat-unoccupied zone. Estimates of tree basal area and tree height were much higherin bat occupied zones compared to bat-unoccupied zones. (Mann-Whitney U test: U = 573.0, p < 0.05), tree basal area (U= 674.0, p < 0.05), tree height (U = 632.0, p < 0.05) and tree canopy cover (U = 329.0, p < 0.05). Holarrhena floribunda(0.34 m2/h) and Ceiba pentandra (0.22m2/ha) contributed the largest basal area (32.94% of the total basal area) whilst Sennasiamea (0.01m2/ha) and Tectona grandis (0.01m2/ha) yielded the smallest basal area (1.17%). In general, bats seem to greatlypatronize areas with higher densities of tall trees than relatively open areas with shorter trees.

<p>Land conversion has caused the function of the greenbelt for reservoir to be less effective. The management of the greenbelt area is needed to maintain the primary function of the reservoir. Therefore, a vegetation analysis in the greenbelt area is necessary to evaluate the condition of the existing vegetation and community attitude to maintain the greenbelt area. This study aims at identifying the current condition of the greenbelt area and the diversity of vegetation as well as the community attitude at the greenbelt area of multipurpose reservoir of Wonogiri. Vegetation sampling was done by purposive sampling using directed line quadrant method, while community attitude sampling was performed using in-depth interviews. This study found 14 species of vegetation in the greenbelt area. The most significant contribution of vegetation species was shown by the Importance Value Index (IVI), with 14 species of tree in which teak (<em>Tectona grandis L</em>.) was the species with the highest IVI value. The species diversity index was 1.15-1.7 and it was included in the medium category. Reforestation efforts can be continued because the vegetation condition has shown moderate stability. Community attitudes towards the greenbelt largely support the existence of management although people still and will use the land without disturbing the existing plants. The reforestation program that has been carried out in the last few years is expected to be able to restore the greenbelt in support of the reservoir function.</p>

Abstract: Butterflies are insects that have a very important role in the ecosystem is as a helper in the pollination in plants. In addition butterfly can also be used as a bio-indicator to changes in environmental quality since butterflies are very sensitive to changes in the ecosystem. The existence of butterflies are under threat at this time step and extinction, this is due to the many forests are converted into other land. Diminishing forests and lands turned into settlement and agriculture. Butterfly existence will depend habitat. Butterfly habitat with the amount of food available is quite the diversity of butterflies is high.The aim of research to determine the diversity of butterflies in Batanghari River Plate in Metro City, the research method used is survey method with purporsive sampling. Butterfly collection done by sweeping follows the line transect technique is applied randomly along the 1000 m. After completion of the identification process we then held classification process. Species diversity index (H) is calculated using the Shannon-Wiener formula. Results of the study found as many as 23 species of butterflies of 5 familia, with the most dominant species is Eurema alitha as much as 136. The diversity of butterflies in the Batanghari River Plate in City Metro categorized bit or lower because it has the value H1 <1.

<p>Anthropogenic impact on the population of ground beetles leads to a change in their numbers, structure of dominance, density, species composition, spectrum of life forms. This makes the beetles Carabidae a convenient and informative bioindicator of the ecological state of biocenoses. The material for this work was the Carabidae collections conducted in June-August 2016-2017 in the park zone of different regions of Barnaul, differing in location, area, hydrological regime, vegetation cover, purpose and anthropogenic load. When processing the material, the quantitative, species and generic composition of the carabidae was determined, calculations were made for such indicators as the Berger-Parker dominance index, the Shannon species diversity index (Hs), and the Jacquard species similarity index. The fauna (Coleoptera, Carabidae) of the park zone of Barnaul is represented by 55 species belonging to 20 genera. The dominant group is represented by species belonging to steppe, forest and polyzonal groups. Forest-steppe species of ground beetles as dominants have not been identified in any of the investigated territories. The greatest variety of ecological groups was noted on the territory of the Yubileyny рark, which is explained by the presence of zones with various microclimatic conditions, the presence of a birch grove that flows through the park with the Pivovarka River, and a wide log in the park. Registered species belong to eight groups of life forms belonging to two classes - zoophagous and myxophytophagous. On the numerical and species abundance, zoophages predominate. The spectrum of life forms corresponds to the zonal spectrum characteristic of the forest-steppe zone.</p><p> </p>

AbstractA total of 176 homestead forests at three altitudes in the Chittagong Hill Tracts, Bangladesh were randomly surveyed to estimate carbon (C) stocks and how stand structure affects the biomass C. All woody vegetations were measured, and litter and soil (0–30 cm depth) were sampled. The tree biomass C stock in the top two altitude forests was up to 37–48% higher than in low altitude, owing to significantly higher tree density and species diversity. An increase in species diversity index by one unit increased the biomass stock by 23 Mg C ha−1. The C stock of litterfall in low altitude forests was 22–28% higher than in the top two altitude due to the deposition of litters downslope and deliberate use of mulch for soil improvement and conservation, resulting in up to 5% higher total soil C. The topsoil C was 10–25% higher than the deeper soil, depending on the altitude. The forest stored 89 Mg C ha−1, indicating a potential for C sequestration in trees outside forest. This study would help policymakers to strengthen the recognition of small-scale forests for mitigation in REDD + (reducing emissions from deforestation and forest degradation, the role of conservation, sustainable management of forests, and enhancement of forest carbon stocks) and support owners through C credits from sustainably managed forests.

It is documented that the amounts of carbon stored and its level of degradation in different forests compositions and different types of forest is mostly unknown, Philippines is no exemption as little was done in some places of this country. This study was conducted to assess carbon stock through above ground biomass of trees at different forest composition in Mt. Malindawag. There were three (3) 20m x 20m sample plots (quadrats) (400m2 equivalent to 0.04 ha) established as replicate plots provided with 50m intervals. Forest composition such as the Agroforestry area, mixed forest area and the Plantation forest were assessed in terms of the number of individuals, number of species, diameter, and height to calculate the biomass, tree biomass density as well as the carbon stock. Based on the results of the study conducted in different forest compositions of Mt. Malindawag, plantation forest has the highest carbon stocking rate. However, these results were not significantly different from the other forest composition. This was associated with a higher accumulated diameter, which resulted in higher biomass and eventually carbon stock. Species found in this forest composition are productive and have lesser number of individuals; therefore, there is lesser competition for resources such as light. Such a mechanism might contribute to the higher biomass and carbon stock. However, the result may not be right to other areas due to uncontrollable factors, anthropogenic and environmental factors. Hence, it is recommended to have further studies on areas where trees have similar age, species diversity index as well as stand development and site productivity for a more accurate and quantifiable carbon stock.
