Soba Village, West Amarasi Subdistrict, Kupang Regency is located in East Nusa Tenggara Province with abundant natural resources. One of the natural resources  is  a natural spring with  abundant diversity of riparian vegetation. The diversity of riparian vegetation around water sources plays an important role in water quality. This study aimed to identify the diversity of riparian vegetation around springs and to determine water quality. The method used was plot installation, identification of riparian vegetation types, measurement of environmental factors and water quality testing. The results showed that there were 12 species of tree vegetation with a total of 74 individuals, the most common tree species found was Canangan odorata with a relative abundance of 24.32%, followed by Cocos nucifera 18.92%, and Areca sp. 16.22%. Meanwhile, the least species found were Tectona grandis, Mangifera indica, Artocarpus altilis, and Syzygium aqueum with relative species abundance of 1.35%. The results of quantitative analysis of the relative frequency found tree species Areca sp. and Cocos nucifera had the highest value, namely 19.05%. Meanwhile, the highest relative dominance value was found in thespecies Artocarpus altilis. The results of water quality testing with 3 parameters namely physical, chemical and bacteriological showed a COD value of 85.03 mg / L, a total colifrorm of 45 and a total fecal colliform  of 230

AbstractBat is animal that occupies aerosphere, especially fruit bats that forage on the space around the trees. The fruit bats use whether narrow space below tree canopy or in edge space on the edge of canopy. Whereas the aerosphere occupancy of fruits bats related to the specific tree species is poorly understood. Here, this paper aims to assess and model the association of fruit bat Cynopterus brachyotis aerosphere occupancy (Ψ) with tree species planted in mountainous paddy fields in West Java. The studied tree species including Alianthus altissima, Acacia sp., Cocos nucifera, Mangifera indica, Pinus sp., and Swietenia macrophylla. The result shows that the tree species diversity has significantly (x2= 27.67, P < 0.05) affected the C. brachyotis aerosphere occupancy. According to values of Ψ and occupancy percentage, high occupancy of narrow space by C. brachyotis was observed in Swietenia macrophylla (Ψ = 0.934, 78%), followed by Alianthus altissima (Ψ = 0.803, 57%), and Mangifera indica (Ψ = 913, 55%). While high occupancy of edge space was observed in Mangifera indica (Ψ = 0.685, 41%), followed by Pinus sp. (Ψ = 0.674, 38%), and Alianthus altissima sp. (Ψ = 0.627, 36%). The best model for explaining C. brachyotis occupation in narrow space is the tree height with preferences on high tree (Ψ~tree height, AIC = 1.574, R2= 0.5535, Adj. R = 0.4047). While for edge space occupant, the best model is also the tree height (Ψ~tree height, AIC = −26.1510, R2= 0.7944, Adj. R = 0.7258).

Physical and flame characteristics of fifteen tree species in South-East Nigeria were investigated. The tree species Daniellia oliveri, Anacadium occidentale, Vitex doniana, Lonchocarpus griffonianus, Gmelina arborea, Nauclea latifolia, Tectona grandis, Mangifera indica, Delonix regia, Newbouldia laevis, Azadirachta indica, Dialium guineense, Terminalia superba, Manilkara obovata and Irvingia gabonensis were identified and named by taxonomists. The aim was to investigate the effects of oven and sun dried densities of timbers on major flame characteristics (ignition time, flame propagation rate, after glow time, flame duration and ash formation) and to establish timber density relationship with the flame properties. Physical properties (density and moisture content) and flame characteristics of all the timbers were carried out using their respective standard methods. Oven and sun dried densities of timbers ranged from 0.39 to 0.97 and 0.45 to 1.16 g/cm3 respectively. Moisture content of oven and sun dried timbers ranged from 8.02 to 11.56% and 8.15 to 11.65 % respectively. The range of values for ignition time were (3.00-10.00) seconds for oven dried timbers and (5.00-10.00) seconds for sun dried timbers. Flame propagation rate ranged between 0.15 and 0.27 cm/s and from 0.09 to 0.25 cm/s for oven and sun dried timbers respectively. The values for flame duration ranged from 12.00 to 56.00 seconds for oven dried timbers and 7.00 to 45.00 seconds for sun dried timbers. Afterglow times of oven and sun dried timbers ranged from 70.00 to 267.00 and 19.00 to 188.00 seconds respectively. Ash formation values ranged from 0.19 to 2.38 and 0.25 to 2.46 % for oven and sun dried timbers respectively. Combustion/pyrolysis pattern of oven and sun dried timbers on exposure to fire was similar. Density related to flame propagation rate, although, for the denser hard woods above 0.60g/cm3 and 0.70g/cm3 for oven and sun dried timbers respectively, this dependence was less straight forward. The flame characteristics of the oven dried timbers compared favourably with sun dried timbers and showed that ignition time, flame duration, afterglow time and ash formation have no clear relationship with timber density.

A study on the implementation of eco-campus in terms of vegetation suitability in green open spaces at Universitas Pendidikan Indonesia (UPI) had been conducted. The purposes of the study were to analyze the actual condition the vegetation in green open spaces at UPI and to analyze the suitable vegetation to be implemented in green open spaces at UPI to support eco-campus. The study employed a descriptive design using cross section approach which studies a certain object in a certain period of time. To distribute the plants, this study used block unit mapping with the help GPA and a program namely ArcGIS. The results of the study show that most (43.51%) of the existing plants at UPI were herbs; 32.82% of them were trees, 18.32% were shrubs, and 2.29% were bushes. In the meantime, in terms of the plants’ function, most of the vegetation at UPI were decorative plants (34.35%), followed by medicinal plants (15.27%) and crops (14.5%). In addition to the aforementioned categories, there were 131 species of vegetation around UPI which mostly lied in the east side of the campus particularly around Isola building. Some of them were Filicium decipiens, Pinus merkusii, Barringtonia asiatica, Artocarpus altilis, Terminalia catappa, Agathis dammara, Lagerstoemia flos-reginae, Tabebuia capitata, Cassuarina equisettifolia,  Mangifera indica, Delonix regi), Bougainvillea spectabillis, Muntingia callabura, and so on. Some were also plants that could only found in certain places such as Elaeocarpus grandiflorus, Mimusops elengi, Altingia exelsa, Elaeocarpus sphaericus, Pterocarpus indicus, Samanea saman, Claoxylon polot, Tectona grandis, Flacourtia inermis, Garcinia mangostana, Ponentia pinnata, Sandoricum koetjape, Brunfelsia uniflora, and Alstonia sholaris. Based on the results of the study, it was also proven that the distribution of the vegetation at UPI was uneven; it focused on certain areas such as gardens and main roads.

This study identified the diversity and distribution of tree species and which vegetable crops are grown beneath them, uses of different plants, to identify the problem faced by the farmer, and to recommend a suitable small scale mixed production system. The study was conducted in three sub districts of the Gazipur district in Bangladesh. Respondents for the survey were selected based on five different farm categories, i.e., tenant, marginal, small, medium, and large farm. The most common species in the study area was jackfruit (Artocarpus heterophyllus, 26.3) and mango (Mangifera indica, 22.5) followed by mahogany (Swietenia mahagoni, 10.3), coconut (Cocos nucifera, 10.0), while low prevalence species was gora neem (Melia azadirch, 0.18) and tamarind (Tamarindus indica, 0.19). A total number of 43 plant species were identified in the homestead of the study area of which 28 were horticultural, and 15 were timber and fuelwood producing species. Total income was found to increase with increase of farm size. A large number of vegetables (32 species) are cultivated in the study area, largely for local consumption. The study showed that stem amaranthus, indian spinach, aroids, sweet gourd, chili, turmeric, eggplant, and radish were grown under shade of jackfruit, mango, date palm, litchi, mahogany, and drumstick trees. Country bean, bitter gourd, sponge gourd, and cowpea were found to grow as creeper on jackfruit, mango, litchi, mahogany, and drumstick trees. Farmers earned cash income by selling trees and vegetables produced in the homestead. Among different tree species, jackfruit was identified as an important cash generating crop in the study area. Scopes for improvement of tree management practices were prevalent in the study area.

AbstractThis study was undertaken to examine changes in the content of pigments and accumulation of metals from vehicular pollution in selected species of roadside trees under vehicular pollution. A major arterial road with heavy vehicle emissions in the Kumasi Metropolis was designated as the polluted site, while Kwame Nkrumah University of Science and Technology Campus was designated as the control site. Four tree species (Terminalia catappa, Mangifera indica, Ficus platyphylla and Polyalthia longifolia) selected for the study were well distributed and abundant in the polluted and control sites. Photosynthetic pigments and levels of heavy metals (Pb, Cu, Cd and zinc) were assessed in their leaves. Chlorophyll and carotenoid contents were determined by absorption spectrometry, while the metal accumulation index (MAI) was used to determine the total metal accumulation capacity of the tree species. We observed a reduction in photosynthetic pigments in the leaf samples from the polluted site. Ficus platyphylla had the maximum reduction in total chlorophyll (49.34%), whereas Terminalia catappa recorded the lowest reduction (33.88%). Similarly, the largest decrease (31.58%) of carotenoid content was found in Terminalia catappa trees and the lowest in Polyalthia longifolia (16.67%). The Polyalthia longifolia, Ficus platyphylla and Terminalia catappa leaf samples collected at the polluted site recorded a higher ratio of chlorophyll a/b. Heavy metal (Cu, Pb, Zn and Cd) accumulation in leaf samples was higher in the polluted site than in the control, as expected. The highest metal MAI value was recorded in Mangifera indica (5.35) followed by Polyalthia longifolia with 4.30. The findings from this study specifically demonstrate that air contamination induced by vehicles decreases the level of photosynthetic pigments in trees subjected to roadside emissions. It is clear that both chlorophyll a/b and chlorophyll/carotenoid ratios will act as very useful stress-level markers. Elevated heavy metal levels in the tree species along arterial roadsides indicate that they serve as heavy metals sink. The change in MAI resulting from different pollution burden is an indication that the removal capabilities of the tree species differ from each other. We therefore suggest M. indica and P. longifolia as potential species to be used in air pollution reduction plans in the city.
