Abstract

The javan green peafowl (Pavo muticus muticus) is a endangered bird species. They have big pressure to the population and the habitat. The fact that the birds are still exist on their local distribution. Behavior ecology of javan green peafowl is dealing with activities, mechanism and strategies of the birds in relation to their environment. The aimed of the study is to obtain data and information of ecological adaptation strategies through the behavior activities, mechanism and strategies of javan green peafowl in-relation to their habitat types. Ad libitum sampling method was used on continuous recording every peafowl activities in relation with duration, frequencies mechanism and strategy were influenced by habitat type’s condition. Chi-squre test was used for statistical analysis to know different behavior has influenced by habitat types. The result shown that the javan green peafowl habitat typse has significant influenced on duration of the activities but not at the activities pattern. The walking during the feeding, select shading places or luxuriant trees close to feeding site, choosing tall trees or emergent trees close to open area as roost site, open area also road as display or dancing area, open area which grow shrubs as nesting site are javan green peafowl ecological behavior strategies. The mechanism and strategies of javan green peafowl behavior ecology are related to avoid from disturbance and to adapt their habitat type’s conditions.

Abstract

The concept of hydrological tank model was well described into four compartments (tanks). The first tank (tank A) comprised of one vertical (qA0) and two lateral (qA1 and qA2) water flow components and tank B comprised of one vertical (qB0) and one lateral (qB1) water flow components. Tank C comprised of one vertical (qC0) and one lateral (qC1) water flow components, whereas tank D comprised of one lateral water flow component (qD1).  These vertical water flows would also contribute to the depletion of water flow in the related tanks but would replenish tanks in the deeper layers. It was assumed that at all lateral water flow components would finally accumulate in one stream, summing-up of the lateral water flow, much or less, should be equal to the water discharge (Qo) at specified time concerns. Tank A received precipitation (R) and evapo-transpiration (ET) which was its gradientof (R-ET) over time would become the driving force for the changes of water stored in the soil profiles and thosewater flows leaving the soil layer.  Thus tank model could describe th vertical and horizontal water flow withinthe watershed. The research site was Cisadane Upper Catchment, located at Pasir Buncir Village of CaringinSub-District within the Regency of Bogor in West Java Province.  The elevations ranged 512 –2,235 m above sealevel, with a total drainage area of 1,811.5 ha and total length of main stream of 14,340.7 m.  The land cover wasdominated by  forest  with a total of 1,044.6 ha (57.67%),  upland agriculture with a total of 477.96 ha (26.38%),mixed garden with a total of 92.85 ha(5.13%) and semitechnical irigated rice field with a total of 196.09 ha (10,8%).  The soil was classified as hydraquent (96.6%) and distropept (3.4%).  Based on the calibration of tank model application in the study area, the resulting coefficient of determination (R2) was 0.72 with model efficiency (NSE)of= 0.75, thus tank model could well illustrate the water flow distribution of Cisadane Upper Catchment. The total water yield was 2.789 mm year-1 from 3,624 mm year-1 of total annual precipitation.  The total water yield comprised of a total runoff of 47.39% and  49.23%  of sub surface flow and base flow.Keywords: tank model, Cisadane upper catchment, base flow, watershed

Abstract

Up to now, montane rain forest of Gunung Gede-Pangrango National Park, faces problem in the form of invasion of exotic plant species into the area.  Location of the area that borders with various land uses, such as Botanical Garden and agricultural land, make it very susceptible toward invasion of plant species from outside the area.  The collapse of large trees which normally constitute a mechanism of natural regeneration, was in fact stimulating the development of exotic species, particularly those which were invasive, inside the area. The objective of this research was to test the competitive ability of endemic species, which in this case was represented by Cleystocalyx operculata and Mischocarpus pentapetalus, toward exotic plant species, represented by Austroeupatoriun inulaefolium and Passiflora ligularis, during 5 months of study.  Growth rate of exotic plant species, as well as the dry weight biomass, were larger than those of endemic species.  Indirect estimation of competitive ability showed that competitive ability (β) of endemic species were 4-5 times less, namely 0.0274 (for C. operculata) and 0.0251 (for M. pentapetalus); as compared with those of exotic species, namely 0.125 (for P. ligularis) and 0.1104 (for A. inulaefolium).  Direct test also proved that competitive ability (β) of endemic species was lower than that of exotic species, as shown by relative crowding value < 1.  Estimation of future competitive ability, using diagram of input/ output ratio, showed also the disability of endemic species to compete with exotic species, where position of input/output ratio points were parallel with equilibrium line y=x. Considering those facts, there is urgent need for controlling these invasive exotic species inside the National Park area to maintain the sustainability of biodiversity and regeneration of endemic species in montane rain forest of Gunung Gede–Pangrango National Park.    Keywords: endemic, exotic, invasion, competitive ability, regeneration

Abstract

The species composition and forest structure of Taman Hutan Raya Bukit Soeharto - East Kalimantan were investigated using transect method through systematic sampling with random start design. During data collection,5 transects of 20 m width and  1 km length of each in Wanariset Semboja forest complex and 10 transects in Pusrehut UNMUL and Protection Forest areas were established. The study shows that species richness of trees in those three forest complexes are relatively similar, however, the regeneration stage in Pusrehut UNMUL forest complex is relatively higher than those in another two areas.  Medang (Litsea firma),  Acacia (Acacia sp.), and Mahang (Macaranga gigantea) are dominant tree species in Wanariset Semboja, Pusrehut UNMUL and Protection Forest areas, respectively.  Mahang (M. gigantea) as pioneer species is also commonly dominated forest regeneration in Taman Hutan Raya Bukit Soeharto.   Based on tree’s  diameter distribution, those forests show balanced uneven-aged forests in which the large amount of trees are concentrated in the height class of 10 to 29 m.  Species diversity of those forests are relatively high (H > 2.5) either for seedling, sapling, pole or tree growth stages, however, those forests show different plant communities (IS < 70 %).

Abstract

This filed research was conducted from Apr 2006 to .Juni 2007 at natural tropical rainforest of the Lore Lindu National Park, Central Sulawesi. The objectives were to study the effect of rainfall properties and vegetation characters on interception losses through mathematical model approach, to estimate the rainfall interception losses and to determine the dominant factors influencing them. Observation of vegetation characters in the study area indicated that the vertical and horizontal structure were in good conditions with high leaf area index (LAI 4.8-6.43 m2.m-2 ), ground cover (68.5-92.59%) and wide canopy at average 5.59 (12.05-9.83 m2 Total rainfall (P) on the first measuring phase (Apr 2006-March 2007) was 1502,6mm for 172 events. Dominant rainfall depth was 0.5-5mm for 78 events with cumulative rainfall at 182.2mm or 12.3%, of P. Dominant rainfall intensity was 1--10 mm per hour for 121 events with cumulative rainfall 140.2 mm or 9.3 % of P. The mathematical relationship between rainfall properties and vegetation characters with throughfall, stemflow and interception loss show that rainfall depth and LAI are two factors that strongly influences as expressed: interception loss: Ic= 0. 786+0.343* P+0.051 *LA I (R2=73,77) Application of this equation and Gash model to the second measurement phase (Apr 2007-Juni 2007) gave good agreement on interception estimate and sensitivity, and considering data requirement and calculation procedure this equation is applicable for interception estimation. The critical point of this result is the rainfall properties on Lore Lindu National Park that is very important to forest management, especially in controlling of flooding.

Abstract

Total income in Sumberjaya sub-district, West Lampung District, Lampung Province is affected by land usesystem composition. Amount of 150 respondents in three villages Tribudi Sukur, Sukajaya and Simpangsari hadbeen interviewed to get the information of household income. Simulation based on land use change scenarios(scenario 1: 13°/o monoculture coffee; scenario 2: 61°/o multistrata coffee; scenario 3: 23°/o forest; scenario4: 30% forest and scenario 5: 84% forest) were done to predict total community income in different typecomposition. Highest total community income occurred when 61 °/o of total area covered by agroforestry base oncoffee, but the lowest income occurred when 84°/o of area covered by forest. Converting 4°/o of existing shruband 9°/o of monoculture coffee to agroforestry base on coffee will increase 12.1°/o total income. In opposite,reforestation all Sumberjaya sub-district areas, except paddy field, horticulture land and settlement willdecrease 92°/o of total income.Keywords: Coffee, community income, scenario.
